(57) Abstract: The invention relates to a method for simultaneous obtaining (I) a fertilizer selected from the group comprising ammonium nitrate, ammonium phosphates, and a combination thereof, and (II) sulfur compounds selected from the group comprising elemental sulfur, SO2, sulfuric acid and sulfate salts, including: (a) introduction containing sulfur oxide and carbon dioxide at a concentration exceeding the concentration of sulfur dioxide in this gas, gas into contact with ammonia and water liquid, resulting in the formation containing sulfur oxide product, and the final gas is characterized by a low content of SO2(b) interaction containing sulfur oxide product formed in stage (a) with a reagent selected from the group comprising nitric acid, phosphoric acid, their mixtures and salts formed due to reactions with the participation of the abovementioned acids, in obtaining fertilizer and sulfur compounds, and (C) allocating at least part of the sulfur compounds from fertilizers. The method allows to combine obtaining fertilizer and sulfur compounds, while fertilizers can be obtained in large quantities and simultaneously reduce air pollution by sulphur dioxide. 2 C. and 10 C.p. f-crystals. In the setup portion of the ammonium nitrate, the ammonium phosphate and a combination thereof, through an indirect neutralization of ammonia with acid selected from the group comprising nitric acid, phosphoric acid and a combination thereof, and (II) sulfur compounds selected from the group comprising elemental sulfur, SO2, sulfuric acid and sulfate salts. Fertilizers are used in large volumes in million tonnes per year. They are used all over the world during most of the year. Some fertilizers are salts obtained by direct neutralization of acids and bases. Main examples are ammonium nitrate, which is usually obtained from a direct interaction of ammonia with nitric acid, and ammonium phosphates, which are usually derived in the interaction between phosphoric acid and ammonia. As a result of this direct reaction of neutralization of energy is released. Applications energy neutralization is limited. Sulfur is used in large quantities, primarily for sulfuric acid, which is used mainly as an acidifying funds in a variety of processes. In most cases, as a result of implementation of such processes receive plaster sent as waste to landfill. Typical with the technical application and gypsum as a by-product, which is sent to waste. Consequently, the consumption of sulfur in such a process leads to the emergence of environmental problems associated with the formation of gypsum. However, H2SO4is cheap and concentrated strong acid, which is thus attractive for use. The severity of this problem could be reduced if there was found a cost-effective way of extracting sulfur compounds from flue gases that would reduce the need for fossil sulfur for use in obtaining phosphoric acid. When fossil fuels are allocated each year many millions of tons of SO2. We developed several methods of absorption of SO2and its conversion into sulfur or sulfuric acid. In comparison with other methods of desulphurization of flue gases of industrial application of such technologies is limited. An important reason for this is the lack of driving force for the allocation of SO2from flue gases and concentration. The absorption of SO2and his selection as such requires energy, usually heat, which in turn are associated with the consumption of additional fuel and the aggravation of the problem. Broblem, which today have to face and which is aimed at solving the main effort. In Annex IV to the Protocol on further reduction of sulphur emissions, signed, in Oslo in 1994, lists the common ways of reducing sulphur emissions when burned: (I) measures to regulate energy consumption, including energy savings and the energy mix, (II) technological means, including the supply of fuel, clean fuel advanced technology combustion modification process and combustion and flue gas desulphurisation (DTG). This last includes wet gas cleaning lime/limestone (MY), the absorption in the spray dryer (ADR), a way of Wellman Lord (STR), purification of gases ammonia (OA) and a combined method of removing NOx/SOx [remove NOx/SOx activated carbon (AC) and the combined catalytic destruction]. Were referred to two new methods that are in the preparatory phase (in 1994) were not considered, namely dry cleaned in the scrubber electron beam (SOAP) and the way Mark 13A. In accordance with the signed, Oslo Protocol on the proportion of plants of wet gas cleaning lime/limestone (MY) account for 85% of all installations DTG. In 1995 sector DTG accounted for 15% of all shaped SO2component of the combustion gases adsorb recycle sludge water-based plaster + pre-treated limestone, followed by neutralization reaction with caso3. The products of this interaction in the future enter into interaction with the air getting mostly dihydrate calcium sulphate. The ability to remove SO2depends on the content SO2in the incoming gas relative flow rate of the slurry and the pH of the slurry. With the aim to minimize the harmful effect of soluble compounds falling within the process together with the flue gas and limestone stream from the absorber is removed by blowing. Before sending in this waste removed by blowing a stream, as a rule, the process for the deposition and removal of soluble compounds in solid form. MY inherent in many of the disadvantages caused by working with solid materials and their return in the process, a relatively low rate of interaction with not miscible with water base (caso3and the fact that from the recycle system remove the solid product, which leads to accumulation of soluble impurities. According to the national Directorate of energy UK, the commissioning of the installation for MY Energomera 2% of the electricity produced for this setup and MY annual technology costs in the amount of approximately $ 50 million. The absorption of ammonia, not a suspension of gypsum/lime, eliminates many of the problems associated with the implementation of MY method, but poses the need to solve other problems associated primarily with the cost of ammonia. Ammonium sulfate resulting from the reaction is a low-grade fertilizer produced as a by-product of many other processes. Thus, in most cases it does not cover the cost of ammonia. The present invention is to combine the receive (I) a fertilizer selected from the group comprising ammonium nitrate and ammonium phosphates, and (II) sulfur compounds selected from the group comprising elemental sulfur, SO2, sulfuric acid and sulfate salts. Another objective is to obtain fertilizer through an indirect neutralization of ammonia with acid selected from the group comprising nitric acid, phosphoric acid and a combination thereof. In addition, the object of the invention is the use of the driving force, subject to obtaining the fertilizer, which is available in large quantities, in many places, and for most of the year, to obtain compounds of sulfur from gases containing oxides of sulphur. One C is for the purposes of the tasks in accordance with the present invention are solved by providing a method for simultaneous obtaining (I) fertilizer selected from the group including ammonium nitrate, ammonium phosphates, and a combination thereof, and (II) sulfur compounds selected from the group comprising elemental sulfur, SO2, sulfuric acid and sulfate salts, including:(a) introducing into contact containing sulfur oxide gas generated due to combustion of serosoderjaschei hydrocarbons and containing carbon dioxide at a concentration exceeding the concentration of sulfur dioxide in gas, anhydrous ammonia and aqueous liquid, resulting in selectively formed containing sulfur oxide product, and the final gas is characterized by a low content of SO2, (b) interaction containing sulfur oxide product formed in stage (a) with a reagent selected from the group comprising nitric acid, phosphoric acid, their mixtures and salts formed due to reactions with the participation of the abovementioned acids, in obtaining fertilizer and sulfur compounds, (C) allocating at least part of the sulfur compounds from fertilizers. The above problems are also solved by the creation of fertilizers produced by the method according to the present invention. In most cases, the sulfur oxide in the gas used in stage (a), represents the SO2, SOAmigo sulfur oxide gas could be used-product of industrial production, providing the combustion of serosoderjaschei hydrocarbons, but most interesting are the combustion gases generated by the combustion of oil and coal. Of particular interest are the cases when using high sulfur fuels. In the preferred embodiment containing sulfur oxide gas is the product of the DTG process, more preferably by DTG MINE. In the most preferred embodiment, the flue gas is treated by MY method or another method DTG to remove at least 90% of SO2component, more preferably less than 80%, and the resulting gas is treated in accordance with the method of the present invention. In the patent US 3421848 described method of disposal of residual gaseous components of processes of production of sulfuric acid and receiving ammonium phosphate, held in the plant for nitrogen and phosphate fertilizers, by means of absorption, SO2from the residual gases ammonia solution and desorption of SO2of sulphite-bisulphite ammonium, which is obtained using an excess of phosphoric acid. However, in this patent focuses on the processing of residual gases containing 0.2% SO2and 0.3% SO3and removed from a plant producing sulfuric acid (see column 2 line 17 and 18), which in this patent is not mentioned and not expected to open for the creation of the present invention an unexpected opportunity that contains SO2gases produced by various industrial processes, including the burning of serosoderjaschei hydrocarbons, which are characterized by the presence of CO2in concentrations exceeding the concentration of sulfur dioxide in these gases may selectively interact with ammonia even in the presence of other impurities such as carbon dioxide, in concentrations exceeding the concentration of sulfur oxide, and from which one would expect the fullness of the interaction between the SO2and ammonia. Moreover, as stated in column 2, lines 45-49, as a result of implementation of this method produces a solution which still has its acidic characteristics and which then must be translated into the setting of the preparation of phosphate fertilizer, which is a mandatory factor for the implementation of the method, because in this patent is also not mentioned and are not offered the method according to the present invention, as evidenced by the following examples, the implementation of which the final solution is either free acid or contains only a small excess of acid. The removal efficiency of SO2with negesti absorbent medium and the rate of solubilization of lime. Thus, on the last or last two stages of this method, technological costs per unit removed SO2be high (especially those associated with recirculation of the sludge). Cost-effective technical solution would be to remove, for example, 70-80% SO2the absorbance of the limestone-gypsum slurry and the rest of the processing in accordance with the method of the present invention. The main advantages of the proposed method are the following: - significant reduction of process costs in an existing installation, MY - significant decrease in capital expenditures in future installations DTG, - removal is generally more significant quantities of SO2per unit of consumable reagent and per unit of produced fertilizers (conversion of all sulfur oxides contained in flue gases, in accordance with the present invention would provide fertilizer in quantities in excess of current needs), - simplified regulation in accordance with the variable's content in flue gases, education in accordance with the present invention, oxides of nitrogen, which in the implementation of MY method are absorbed together with the SO2and widely the plants MY acceptable for fertilizer application, - ability in the implementation of the method according to the present invention processing removed during the cleaning process lime DTG material, - high flexibility in the regulation characteristics of the mixture of reactants and products for the local and periodic needs by varying the ratio between the absorption of lime sludge and absorption of ammonia. Thus, in many cases the method according to the present invention not only is more preferable than MY method, but in accordance with it is possible to improve existing and future installations of the MINE. The achieved improvement is superior improvement, which reach a combination of lime and ammonia or ammonium salts in the absorption medium, as proposed in publications such as WO 96/04979, US 5017349 and US 5510094. In a preferred embodiment, after removal of fly ash and temperature control containing sulfur oxide gas is introduced into contact with ammonia and water liquid, resulting in the formation containing sulfur oxide product, and content of SO2in the gas decreases. The ammonia can be introduced in the form of a solution or in gaseous speaker ammonium sulfate, the ammonium sulfite, the flow generated in the next stage, such as the mother liquor from the stage of allocation (as) or stream from another process, such as the waste stream from the installation are MINE. As a result of absorption of the resulting product contains sulfur oxides. Flue gas includes sulfur, mainly in the form of S(IV), but some spontaneously oxidized to S(VI), so that the liquid from step (a) contains sulphites and sulphates. If necessary, in particular in cases where the formed sulfur compound is a sulfate salt, the solution can oxidize preferably air or oxygen-enriched air to convert most or all of sulfite to sulfate. Methods such oxidation is widely represented in the literature on DTG. Containing sulfur oxide product, which can be in solid or liquid state, enter into an interaction with a reagent selected from the group comprising nitric acid, phosphoric acid, their mixtures and salts formed as a result of reactions with participation of these acids. Due to the interaction produces fertilizer and sulfur. When used as reagents, acids or acid salesnotes solution decreases. If the sulfur oxide in the liquid for simplicity present in the form of ammonium sulfite, some of the reactions to this stage can be displayed as follows: (I) (NH4)2SO3+H3RHO4-->(NH4)2HPO4+ +SO2+H2ABOUT (II) (NH4)2SO3+2N3-->2NH4NO3+ +SO2+H2ABOUT (III) (NH4)2SO3+2NH4H2PO4-->2(NH4)2HPO4+ +SO2+H2O During the course of these reactions, as well as subsequent chemical mechanism could be much more complex than presented above equations. When carrying out the known methods of absorption-desorption processes DTG (see , for example, US 5458861, US 5547648, US 5591417, US 5294409, US 5202101, US 5213779, US 5120517 and US 5223237) for desorption of the absorbed SO2you must inform thermal energy. According to another method described in Ont. Hydro Res. Q.(1975), 27(2), 19-28, SO2absorb ammonia. To highlight the SO2the resulting solution is injected into the interaction with NH4HSO4. Formed (NH4)2SO4are subjected to thermal decomposition to ammonia and NH4HSO4returned to the process. Although SO2is viewshow force. Spent on the allocation of SO2energy is heat, it is reported indirectly by decomposition of ammonium sulfate to ammonium bisulfate. In contrast, in the implementation of the proposed method the main part of SO2produced during the reaction is separated in the vapor phase without any needs in the supply of energy. Energy is released in the indirect neutralization. If necessary, the destruction of SO2can be supplemented by heating, for example during concentration/crystallization solution fertilizers. Contained in the vapor phase SO2you can oxidize to SO2according to well known methods, and then to sulfuric acid or to restore to sulfur in the interaction with the reducing agent. Using suitable reagents and, in addition, an optional catalyst in the liquid phase can be oxidation and in particular the restoration. In the case of units located near the units for production of phosphoric acid, particularly suitable for reactions in equations (I) and (III). In these cases, SO2highlighted in the process, can be used to obtain sulfuric acid for fosforescente installation. Acceptable REAG is Tania (even when these salts are not in the acid form). In the case of oxidation of sulfites in the liquid, resulting in the implementation of the present invention at the stage (a), to sulfates such salt is selected from the group comprising calcium nitrate and acidified calcium phosphate. In such cases, the sulfur oxides are mainly in the form of S(VI). Introducing the fluid that enters into interaction, as including (NH4)2SO4as some of the reactions that may take place that can result in equations of the following reactions: (IV) (NH4)2SO4+Sanro4-->(NH4)2HPO4+ +CaSO4< / BR> (V) (NH4)2SO4+Sa(N2RHO4)2-->NH4H2PO4+ +CaSO4< / BR> (VI) (NH4)2SO4CA +(NR3)2-->2N4NO3+ +CaSO4< / BR> Sanro4and Sa(N2RHO4)2are regular interaction products of phosphoric acid with calcium phosphate or phosphate rock, but, if needed, can be obtained by reaction of phosphoric acid with calcium bases. CA(NO3)2can be obtained by reaction of nitric acid with the oxide, hydroxide or calcium carbonate. In a preferred embodiment, the quality is acidifying means. Although phosphoric acid is obtained, as a rule, the influence of phosphate rock with sulfuric acid, in some places it is produced by impact on phosphate rock with nitric acid. This method is called nitrophenyl method. A byproduct is calcium nitrate, in which agriculture is a source of nitrogen. Its use as such is associated with some difficulties, mainly due to its high hygroscopicity. Typically, it is introduced in the interaction with the formation of double salts of General formula CA(NO3)21H4NO3. The content of nitrogen in the fertilizer of both forms is relatively low. If we take into account the objectives of the present invention, it is acceptable any form of calcium nitrate, including all possible products NITROPHENOL process. The use of nitrate of calcium in the implementation of the proposed method are formed substantially large number of target fertilizer with about double the content of nitrogen, a combination of ammonium and nitrate nitrogen and the lack of ballast. In the case of calcium nitrate as a result of NITROPHENOL process manufacturer of calcium nitrate also saves on technologies at the stage of absorption, and acid (nitrogen, phosphate or a combination thereof) is administered at a different stage. Thus formed ammonium salt of the acid. Thus, in General, the process related to equation (I), in a simplified form can be represented as follows (see equation IX-XII). In General, the interaction related to equation (IV), in a simplified form can be represented as follows (see equation X-XIV). Used in the present description, the formula CA3(RHO4)2could be calcium phosphate as such, but in most cases it refers to the calcium phosphate in the phosphate rock, which in fact corresponds to a more complex formula. In General, the interaction related to equation (VI), in a simplified form can be represented as follows (see equation XV-XIX). SO2resulting from any of the processes in which the reagent is an acid or acidic salt, can be used to obtain the phosphoric acid used in stage (VIII) and (XII) (see equation XX-XXII). It is also possible other combinations, such as using on stage (VIII) or (XII) H3RHO4obtained in stage (XVII). the ol in the quality of the product or, at least part of it is produced from the base, ammonia and acids, which are injected at separate stages of the method. Thus, their interaction is indirect, and the energy of neutralization in the form of thermal energy not allocated either entirely or partially. Instead, during the process such energy, in some cases jointly with other energy types, in particular with the energy of crystallization, provides the driving force allocation SO2from its containing gas and the concentration of sulfur compounds intended for use as such or transformation into other compounds of sulfur. According to patent US 5624649 (in the name of General Electric Co.) provided by the absorption of SO2ammonia, oxidation of the resulting ammonium sulfite to ammonium sulfate and the interaction of the latter with potassium chloride to form ammonium chloride and potassium sulfate. This last reaction is performed in an ammonia environment, and its flow is simplified by the low solubility of K2SO4in this environment. Ammonium complex environment in circulation, which results in losses and a strong ammonia smell. In this method according to the above patent get ammonium sulfate and conduct its reaction with Solovieva method in several important aspects. Salt reagent represents KCl, which get rather in the form of a mineral and not as a product of interaction involving phosphoric or nitric acid could be obtained by the reaction of potassium base with Hcl, but this is uneconomical). As the ammonium salt in the above-mentioned U.S. patent get ammonium chloride, but not nitrate or ammonium phosphate, as in the proposed method. While ammonium fertilizers according to the present invention has a better quality ammonium sulfate, the implementation of the method according to the aforementioned U.S. patent ammonium fertilizer is deteriorating from the sulfate to chloride. However, the main difference is that in the implementation of the method according to this U.S. patent, the acid is not consumed (except for SO2) and therefore not allocated any energy neutralization, which can be used as the driving force. In the patent US 4168150 described a method of producing fertilizer, which, among other things, involves the removal of sulfur oxide due to the interaction with calcium maintenanced phosphate rock. Thus, unlike the proposed method for conducting the reaction of SO2with phosphate rock (which is optionally pre-treated) and not with Ah conditions, required for the activation of phosphate rock. Upon absorption of SO2this acidity is counterproductive. The separation of sulfur compounds produced by this method involve technical difficulties, and therefore it is contained in the received fertilizer. As according to US 5624649, there is no appreciable flow of nitric or phosphoric acid, so that there is no appreciable indirect neutralization and due to its driving force. The fertilizer produced during the implementation of the method according to the present invention can be used in solution or in crystalline form. As the energy for the evaporation of water it is possible to apply thermal energy of the combustion gases. The presence of SO2in solutions of fertilizers is undesirable because most likely it would lead to the volatilization of SO2in atmosphere. Also, the SO2so it can be used in such applications as processes of soaking, getting sulfites and bisulfites and for transformation into other sulfur compounds, primarily into elemental sulfur and sulfuric acid, it is necessary to separate. Due to its volatility SO2stands out is relatively easy, especially in acidic solutions. some of them are even necessary. However, obtaining fertilizer with a high content of sulfur compounds may be undesirable because of the relatively low solubility of some sulfate salts when used in many purposes could be considered a drawback. As a result of reactions in the stages (XIII) and (XIX), as well as other reactions involving calcium salts of nitric acid, are formed having a high solubility in water ammonium nitrate, phosphates or combinations thereof and is not miscible with water gypsum. The solubility of gypsum is particularly low in neutral solutions, such as solutions of ammonium nitrate and secondary acidic ammonium phosphate. In the course of the reaction conditions can be adjusted so that it formed a large gypsum crystals, which are easily separated by filtering and washing. The formation of such crystals contributes to elevated temperatures and careful mixing. In the application EP 0670750, filed in the name of the present applicant, describes a method of reducing air pollution caused SO2by becoming SO2in the calcium sulfite. Containing SO2gas is injected into the interaction with ammonia and aqueous liquid with a receipt containing the SO2the product of the formation as a by-product of technically useful ammonium salt. In some circumstances, the calcium sulfite is less desirable by-product than gypsum, in particular when there is the possibility of recycling of gypsum, for example, in the manufacture of wallboard, dry plaster. Furthermore, in acidic conditions at a technological stages, and when storing a number of SO2able to escape. The method according to the above-mentioned application could be implemented with subsequent oxidation of calcium sulfite to calcium sulfate, as, for example, has a place in MY process. It might even give some of the benefits associated with lower solubility of calcium sulfite than gypsum. However, in many other cases before the interaction with the calcium salt as a reagent containing a sulfite liquid from the first stage it is preferable to oxidize. At the time of filing the aforementioned European application when creating the present invention was not obvious higher economic benefit from the implementation of the method, based on the possibility of oxidation of sulfite to sulfate, which is a feature that is currently used for the first time in the proposed method. Gypsum crystals obtained in accordance with the present from the nose due to repeated circulation due to the use of centrifugal pumps high pressure. Another advantage in comparison with MY method are more pure gypsum crystals that are free from lime/limestone, inevitable impurities when carrying out MY method, in which the lime/limestone as the reagent is mainly in the solid state. Another advantage in the case of using calcium nitrate NITROPHENOL process or acidified calcium phosphate is the lack of consumption of lime or limestone. In those cases, when the present invention is a calcium salt as a reagent obtained by reaction of the acid with lime or limestone, the latter usually spends almost stoichiometric amount and, thus, much less than MY method. This is because its on the reaction stage (b) impose, in contrast to what takes place in MY method, in the form of soluble compounds. Although in the following the invention is described in more detail on the example of some preferred variants of its implementation, however, they do not limit the scope of the invention. Moreover, it should be noted that the scope of the invention defined by the attached claims may be included all alternatives, modifications and equivalents of the tion, serve to illustrate the possibilities of practical implementation of the present invention, and it should be noted that the examples of items presented only as an example to illustrate the preferred embodiments of the present invention to explain the processes of preparing the compositions, as well as of the principles and conceptual approaches proposed in the invention.
