Proposed automated method of controlling and managing the process of preparing sugar syrup mixture for crystallisation by cooling makes provisions for regulating the volumetric discharge of water entering the mixer and the level of sugar syrup in it. Regulating the level of the sugar syrup in the vertical mould is achieved by acting on the adjustable-frequency electric drive of the sugar syrup pump. Periodically using the lab the density of the ready sugar syrup is controlled at the exit from the mixer. The active electrical power which is used in the electric motor of the sugar syrup pump, the temperature and pressure differential of the sugar syrup mixture, coming from the mixer and water at the entrance of the mixer are all measured. The water-mass density is calculated by its temperature and the density of the sugar syrup mixture by its pressure differential. Afterwards the volume flow rate is worked out by the measured volume flow rate of water, by the estimated value of the density of water and sugar syrup mixture and by the density of ready sugar syrup measured in the laboratory. The dependency ratio of the active electric power from the volume rate of flow of the sugar syrup mixture and the differential in its pressure N=α1Q3 УΔPy+α2QyΔPy , where N - active electric power; QY - volume rate of flow of sugar syrup mixture entering the mixer; ΔPY - pressure differential of the sugar syrup mixture; α1, α2 - coefficients. The obtained plot is used for future calculations of volume rate of flow of sugar syrup mixture only with measured values of active electric power and pressure differential of the sugar syrup mixture. The current task of the regulator of the volumetric water discharge is determined on the basis of measured values of this output, estimated values of the density of sugar syrup mixture, water and volume rate of flow of the sugar syrup mixture, the determined value of density of ready sugar syrup mixture and the task of the regulator calculated in the previous control step. The solid content of the original sugar syrup mixture is controlled - by its temperature and density in the ready sugar syrup mixture. This invention makes it possible to reduce the loss of sugar from molasses due to a more qualitative stabilisation of the density of molasses on its exit from the mixer.

Group of inventions relates to the oil industry, in particular to methods and devices for dispensing reagents demulsifiers and corrosion inhibitors - the collection and preparation of oil and water emulsions, and can be used on the oil treatment plants and preliminary water discharge, i.e. when the joint transport the produced oil and gas. There is a method of dosing of chemicals (emulsion) in the collection and preparation of oil, namely, that the production from the wells flows into the container located inside the tank with a demulsifier, washes the tank. Then the dosing pump demulsifier served in the dispenser, through the holes which he uniformly across the cross-section of the vessel is introduced into the volume of the pumped boreholes. Mixed with demulsifier production wells re-enters the pipeline from production wells [RF Patent №2049519, CL 01D 17/04, publ. 1995.12.10]. The disadvantage of this method is the complexity of its implementation. Known device for dosing of chemicals (emulsion) in the collection and preparation of oil, including the pipeline gathering system production wells, the reservoir for the chemical with the sockets for input and output of chemical and air release, dosing pump connected to the tank, while the plant is equipped with the capacity with the introduction and in the water pipes, connected to the pipeline gathering system production wells, and an annular perforated distributor connected to a dosing pump, and a reservoir for the chemical and the distributor is installed inside the tank [RF Patent №2049519, CL 01D 17/04, publ. 1995.12.10]. The disadvantage is the complexity of the layout of the installation, and the impossibility of accurate dosing of the chemical. There is also known a method of dispensing reagents, namely, that in technological capacity, designed for the preparation and storage of reagent injected reagent. The level of the reagent is measured by the sensors. Further from the technological capacity of the reagent is supplied to the reception of a dosing pump. Alternate dosing of the reagent in the pipeline with the pumped medium or technological capacity is tripped [RF Patent №2171790, CL 02F 11/14, publ. 2001.08.10]. The disadvantage of this method is the complexity of the regulation of the SOS periodic dosing of the reagent, and that not by intensive mixing of the reagent with the pumped medium because after breaker flow becomes laminar character. A device for dispensing reagents - block cooking chemicals block installations, including technological capacity chemical, pipeline re achiveve environment, the dosing pump, the output of which is connected through the circuit breaker, providing alternate connection of the output of the pump through the pipe strapping to the technological capacity of the reagent. Breaker periodic dosing of chemical reagent in the pipeline with the pumped liquid [RF Patent №2171790, CL 02F 11/14, publ. 2001.08.10]. The disadvantage of the block of preparation of chemical reagents is the presence of a dosing pump, which provides no flow control, the complexity of the regulation of the SOS periodic dosing of chemical reagent in the pipeline with the pumped liquid, because the breaker is made in the form of a valve device or a rotating rotor with slots and holes, does not provide a clear uninterrupted operation of the unit. The closest way to the same destination to the claimed method in a group of inventions on the totality of symptoms is the way the dosage of the reagents, namely, that the reagent by gravity through the filter goes to the reception of a dosing pump, which regulates the flow rate of the reagent, and then fed into the pipeline with the pumped liquid. [Brochure "OZNA DISPENSER" joint stock company "OZNA", "Modification MDD performed with two dosing pumps, without spending capacity, without mixer", p.12-13 - Bashkort Republic of the mill, gontarski, street North, 60, see Appendix]. The disadvantage of this method is the complexity of the dosing of the reagent by regulating its flow by the dosing pump, which provides no change in dispensing of the reagent when the change in the flow rate of the pumped fluid. In addition, pump-dispenser reagent is served in the pumped flow in pulse mode, which leads to the interaction of the reagent with a certain portion of the reagent. In this part of the reagent is beyond the field of interaction with the reagent, i.e., not intense mixing of the reagent with the pumped medium. The closest device to the same destination to the claimed device in the group of inventions on the totality of symptoms is the device - unit dosing of reagents, including technological capacity, intended for storage of the reagent. The unit contains a level sensor, temperature sensor and gauge, as well as the filter and the pump, carry out continuous volumetric dosing of reagents - liquid demulsifiers and corrosion inhibitors in the pipeline with the pumped liquid. This unit dosing of the reagent is performed in a block design. The equipment unit is mounted on a welded frame and is insulated room [brochure "OZNA DISPENSER" joint stock company "OZ IS A", "Modification of MDD performed with two dosing pumps, without spending capacity, without mixer", p.12-13 - the Republic of Bashkortostan, gontarski, oseira, 60, see Appendix]. Lack of unit dosing of reagents is the complexity of the structural design, the use of several expensive pumps, various devices, in particular the level sensor, temperature sensor and so on, which creates the complexity of regulation by dosing the reagent, as well as significant energy consumption. In addition, the dosing unit has a bulky design, placed on a welded frame, and must be insulated room. The technical result is to facilitate the dispensing of the reagent in the pipeline with the pumped liquid due to the automatic regulation of the flow rate, simplifying the design, reducing the metal and energy consumption due to elimination of dosing pumps, hull and equipment unit mounted on a welded frame, as well as providing intensive mixing of the reagent with the entire volume of the medium pumped through the creation of turbulent flow during the passage of the fluid through the site of the narrowing. Specified single technical result in the exercise of invention the object of the method is achieved by the reinforcement of the coherent method of dispensing reagents into the pipeline with the pumped liquid by regulating its flow, the peculiarity lies in the fact that pre-equalize the pressure in the vessel with reagent and gas associated gas, and then regulate the flow rate of the reagent, by comparing the measured flow of the reagent is the reagent consumption in the regulator with a set value of the flow rate of the reagent, and the difference between these two values is generated control signal to the regulating valve mounted on the pipe connection of the nozzle with the container.

The presence is Truboprovod with the pumped liquid pipeline of smaller diameter provides a greater rate of passage of the pumped fluid and turbulent hydrodynamic flow regime environment. The placement of the nozzle pipe section of smaller diameter creates a vacuum, through which the reagent is sucked into the pipe with the pumped liquid and then intensively mixed with it. Automated system for dispensing reagent provides an instant assessment of consumption and accurate dosing of reagent consumption. The claimed group of inventions to meet the requirement of unity of invention, since the group of inventions forming a single General inventive concept, both group object of the invention is aimed at solving the same problem for a single technical result.

When this is included in the work of the nozzle 4. When the movement of the pumped fluid by a slim section of the pipeline in the position of the nozzle 4, a vacuum, which increases the pressure difference between the nozzle 4 and the tank 1, as a result of the supplied reagent is sucked into the pipe 2 with the switch is cinemoi environment and intensively mixed with it.
