FIELD: physics, measurements.
SUBSTANCE: invention is related to facilities for odorisation of natural gases and may be used in gas, oil and other industries. The result is provided due to the fact that working, consumption tanks are used, as well as reservoir for storage of odorant, which are connected between other by pipelines, odorant is supplied into working reservoir from reservoir for its storage by means of creation of pressure difference between reservoir for its storage and working reservoir, afterwards, odorant is pumped from working reservoir into consumption reservoir, from which odorant is dosed into gas line, proportionally to gas consumption. Besides odorant is pumped from working reservoir into consumption reservoir by excess pressure from high pressure gas line, and in consumption reservoir pressure is created, which is equal to pressure in low pressure gas line, level of odorant in consumption reservoir is maintained as permanent with the help of float valve, and in working reservoir odorant level is controlled by detectors of upper and lower levels, process of working reservoir filling with odorant and its pumping into consumption reservoir is done by signals from level detectors with the help of electric valves, and batching is done from system of commercial accounting of gas consumption.
EFFECT: higher accuracy of batching.
The invention relates to methods for proportional dosing, particularly for odorizing natural gas, and can be used in gas, oil and other industries.
The closest to the technical nature of the claimed method is a method of automatic odorizing natural gas, which is implemented in the device (see Adevarul and other Automatic dispenser of natural gas, "Gas industry", 10, 1995, pp. 28-30, Fig.1, in which use the working container, filled with liquid odorant. The lowest point of the working tank is connected by highway with feed tank through the level regulator, consisting of a movable locking element rigidly connected with the float. The gas cushion of the working tank is connected by highway with a gas cushion the supply tank. Odorization contains a regulatory body made in the form of a vertical tank, the cavity of which has a variable height of the cross-sectional area. The highway connects the lower end of the feed tank with bottom vertical capacity through the normally closed valve with the drive magnet. Narrowing device torestore made in the form of dimensional washers installed in the output pipeline GDS (gas station) between two annular what ameres. When the gas movement in the pipelines for measuring the washer there is a pressure drop. Therefore, in the first direction of motion of the gas cavity pressure is higher than in the second direction of gas flow. The highway connects the gas cushion the supply tank with the first annular chamber. The second camera one line is connected with a gas cushion in a vertical tank, the other highway - with bottom feed tank through the normally open valve with the drive magnet. Odorization controlled from the generator, producing electric pulses supplied to the solenoids of the valves through the same periods of time.
The above method is selected as a prototype. The disadvantages of the above method are the low accuracy of dosing and large dimensions odorizing system, because the entire stock of odour is in working capacity. To create excess pressure in the working capacity is used, the pressure in the output pipe of the GDS, so that the production capacity becomes regulated as a vessel operating under pressure, and this is due to significant cost of operation of the installation. Change this pressure reduction is impossible, because it violates the algorithm odorizing system. The odorizing system, which has low precision dosing, as dosing goes black is C equal intervals and instantaneous gas flow rate (dose measured by the actual pressure drop on the gauge washer in the opening of the valve on the highway, connecting the supply tank with vertical capacity and high flow gas odorizing system will not have time to measure out the dose and gravity to give it in the pipeline).
Solved technical problem is to provide a method of automatic odorizing natural gas, high precision batching, which can be used for maintenance of the GDS in a wide range of gas flow.
Achievable technical result of the proposed method is fully automatic process odorizing natural gas.
To achieve a technical result in the claimed method automatic odorizing natural gas, which consists in the fact that the use is in operation, the feed tank and the storage capacity of odour, interconnected pipelines, serves the odorant in the working capacity of the tank for storage by creating a pressure differential between the capacity for storing and working capacity, followed by pumping of odour from the working capacity in the account from which you make the dosing of the odorant into the pipeline, in proportion to the gas flow, it is new that the transfer of odour from the working capacity in the expenditure carried out by the excess pressure of the high-pressure gas, and in the supply tank creates a pressure equal to the pressure in the pipeline with low the m pressure the level of odorant in the supply tank support constant by a float valve, and the working capacity of the control of odour sensors of the upper and lower levels, the processes of filling of the working capacity of the odorant, the transfer of odour in the supply tank is manufactured using ejector operating in two modes: create a vacuum in the working tank when filling and pressurization of the working capacity high input pressure, the transition from pressurization of reservoir filling it is controlled by signals from sensors levels using solenoid valves and dosing carry out from the system of commercial metering of gas.
The inventive method is implemented by the device represented in the drawing. The device has the capacity to store the odorant 1, working tank 2, the supply tank 3 connected by pipes 4. High pressure in the working tank 2 is fed through the ejector 5, which has three connections: high pressure 6, low pressure 7 and rarefaction 8. Fitting high pressure 6 is connected to the input pipe 9 GDS, fitting low pressure 7 is connected to the output pipeline 10 GDS, and the fitting depression 8 to the working vessel 2. The supply tank 3 is a chamber with a float valve which, when the maximum permissible level of odour in the least shuts off the supply of odour from the working vessel 2. The gas cushion above the odorant in the supply tank 3 is connected with the outlet line 10 GDS. The bottom part of the supply tank 3 is connected to the pipeline through which the odorant through the dispenser 11 is supplied to the output pipeline 10. On the pipeline connecting the working 2 and the supply tank 3 has a check valve 12, excluding the message of tanks during refueling of the working tank 2. On the piping that connects the working tank 2 and the storage capacity of odour 1, a check valve 13, precluding the flow of odorant from the working capacity in a storage tank in the process of spending the odorant from the working vessel 2. There pressurization system storage tank 1 of odour. For pressurization is used, an inert gas from a cylinder or gas from the inlet pipe 9 GDS. The boost pressure is maintained balloon gas valve 14, configured for pressure not more than 0.06 MPa. Control of gas flow is normally closed solenoid valves 15, 16. Their on and off simultaneously by signals from sensors levels 17, 18 located on a working vessel 2.
The method is as follows.
In the initial state, all manual valves in the system are closed.
The odorant is delivered at GDS car-torontobased in the tank. The tank is connected by a hose 20 with the filling of the hand is the leader in storage tank 1 of odour. In the odorizing system open manual valves K1, K10. By adjusting the manual valve C7 achieve manovacuummeter MB the required degree of vacuum and open the hand-operated valve K5. When this occurs, the vacuum storage capacity of odour. In the tank tarantulas creates the necessary overpressure of inert gas from a cylinder of tarantulas) and opens the valve on the tank. The odorant under the action of the generated differential pressure fills the storage tank to a certain level controlled by the level sensor 19 from the ACS of GDS. After receiving the signal from the level sensor 19 on the lling of the filling process is terminated. The valve on the tank, valves K5, K10 and K12 are closed.
The process starts with filling the working capacity of the odorant. For this purpose it is necessary to apply power to the control system of odorization. When the level sensor 17 in the working tank will show the absence of odour, and the control system will issue the command to open the solenoid valves 15 and 16. After this regulation crane C achieve the required degree of vacuum at manovacuummeter MB. Then open the hand-operated valve K6 and ejector vacuum working capacity. Then open the hand-operated valve K9. Thus there is an equalization of pressure in the supply tank with pressure in the output pipe. Under esteem output pressure and vacuum created in the working tank check valve 13 closes off the flow of gas from the supply tank into the work. Next, with the help of a balloon valve 14 is set to a pressure of 0.06 MPa in storage capacity of odour. Under the action of the charge pressure in the vessel, the odorant storage and rarefaction in a production capacity created by the ejector odorant through the check valve 12 fills the working capacity of up to trigger the level detector 18.
The sensor 18, the control system issues a command for closing the solenoid valves 15 and 16, this cuts the charge storage capacity of odour, as this is blocking the road connecting the ejector with the outlet line (with the area of low pressure), and in the working tank through the ejector 5 and the fitting 8 enters the high pressure (inlet pressure GDS). Under the action of this pressure, the odorant closes the check valve 12 and, overcoming the output pressure of the gas in the supply tank (low pressure), opens the check valve 13. The odorant fill the supply tank to a level at which the float valve closes and stops the flow of odorant from the working capacity.
The gas cushion above the odorant in the supply tank connected to the outlet line of the GDS. The bottom part of the supply tank is connected to the pipeline through which the odorant through the dispenser 11 is supplied to the output pipeline 10. Thus, the pressure at the inlet to the dispenser and at the outlet of the dispenser is output is the pressure GDS, that allows you to use the dispensers of various designs, up to a drip, and in our case we used the dispenser plunger type CLII. .........controlled from the system of commercial metering of gas that is present on all GDS.
While using the level of odorant in the supply tank drops, the float valve opens and the replenishment of the supply tank by the odorant from the working tank. This process will be repeated until such time as the level of odorant in a production capacity reaches a level of the sensor 17. From the sensor 17 at the command of the control system and simultaneously the solenoid valves 15 and 16, it triggers the ejector (settings ejector has not changed, the valves do not overlap) and a vacuum is created in the working capacity and charge capacity of the odorant storage (settings balloon gearbox also has not changed). Under the action of the created pressure differential odorant fills the working capacity to a level that triggered the sensor 18. When the charge storage capacity of odour stops working capacity is inflated high (inlet) pressure in the supply tank through the check valve 13 begins to receive the odorant.
The described process will be repeated until when the level sensor 19 of the odorant in the tank for the storage of 1 will indicate the need dataprev and capacity of the odorant. This process is performed manually without stopping the process tarirovanija gas in the previously described sequence. A necessary condition of continuing to tonirovaniy gas is that the stock of odour in the supply tank was missing at the time of charging of the storage capacity of odour. Because the storage capacity of odour is calculated at 2 months of GDS operation at the maximum gas flow, the process of refueling capacity will theoretically be no more than 6 times per year, but in practice much less.
The dimensions of the working capacity for its withdrawal from supervision are selected from the condition
where P is the pressure in the vessel, in kg/cm2,
V - volume, liter.
The inventive method odorizing natural gas is fully automated through the use of free for GDS energy source - differential gas pressure at the inlet and outlet pipelines GDS created a closed process without emission of harmful vapours of odour in the atmosphere. Due to the fact that the system tarirovanija gas to displace the odorant from the working tank is a high pressure gas and to output this capacity under the supervision necessary to meet the condition P×V<200, the dimensions of this capacity is minimal, but that does not prevent its use due to the automatic refuelling process (described previously). Dose the Finance of odour electromagnetically dispenser plunger, outstanding strictly off-trade volume for each stroke of the plunger receiving control pulses from the system of commercial metering of gas flow, which can significantly improve the accuracy of dosing of odour. Compliance with the design of the containers allows you to take them under supervision and significantly reduce the cost and simplify the operation of the system.
The method of automatic odorizing natural gas, which consists in the fact that the use is in operation, the feed tank and the storage capacity of odour, interconnected pipelines, serves the odorant in the working capacity of the tank for storage by creating a pressure differential between the capacity for storing and working capacity, followed by pumping of odour from the working capacity in the account from which you make the dosing of the odorant into the pipeline, in proportion to the gas flow, characterized in that the pumping of odour from the working capacity in the expenditure carried out by the excess pressure of the high pressure gas pipeline and storage tanks create a pressure equal to the pressure in the gas pipeline of low pressure, the level of odorant in the supply tank support constant by a float valve, and the working capacity of the control of odour sensors of the upper and lower levels, the process of filling in RA the eyes of the odorant tank and pumping it into the supply tank is produced by signals from sensors levels using solenoids, and dosing carry out from the system of commercial metering of gas consumption.
