Description

one

The invention relates to the analysis of dispersion media, in particular to the analysis of oil-water emulsions, and can be used in automated control systems for technological processes of preparation: oil on oil fields.

A device is known for. determination of dispersion using Figurovsky to.

The disadvantage of this device is that it is a laboratory-type device, and therefore its application in the ACS is almost impossible.

It is also known to use a laboratory-type device for determining the water content in t23 oil products, which has the same drawbacks as a device for determining the dispersion.

Closest to the proposed technical entity is a device for automatically measuring the parameters of oil-water emulsions, which contains a moisture meter sensor mounted on the sampling pipe and connected to the secondary instrument СЗ 1.

The disadvantage of this device is low efficiency due to the absence of the possibility of determining simultaneously with humidity and dispersion without introducing additional dates. chi ko in,

The purpose of the invention is to increase the efficiency of the device by increasing the range of parameters to be determined.

This goal is achieved by the fact that the device is equipped with a sample accumulator with inlet and outlet nozzles located at different levels of the accumulator, shut-off elements yQ installed on all communication lines, and a control unit connected to the control inputs of all the locking elements, while the input the moisture sensor sensor is connected through the corresponding locking elements to the upper and lower levels of the storage device, and the output is from the middle level. The drawing shows a block diagram of a device for automatically measuring the parameters of the oil and water Pulse. The device consists of a sampling device 1, a sampling filter emulsion from the process pipe 2, a moisture meter sensor 3, a secondary device, a control unit 5, a pump 6, a sample accumulator (settling tank) 7 and locking elements (valves) 8-1i. As a moisture meter sensor 3, a digital moisture meter CVN-2 for crude oil, based on the dielectric method, is used. The device works as follows. Vodoneft on the emulsion flowing through the process pipeline 2 is sampled by the sampling tank 1 and the open shut-off elements 9 12 and closed 8, 10, 11 and 13 flow through the sensor 3 of the moisture meter and return to the pipeline 2 "Electric signal containing information on the current humidity value the emulsion enters the secondary device, where it is converted into the display of an indicator or a recording device. To measure the dispersion of the emulsion, the control unit 5 at a certain moment gives commands to close the valves 9, 12 and open the valve 8, through which the emulsion will send 7 samples to the drive. By filling it to a certain level, the valve 8 closes (a signal to close can come, for example, from a level sensor that is not shown). After that, the control unit 5 periodically at certain time intervals At sends signals for opening the valves 10, 13 and switching on the emulsion supply device (for example, the piston pump 6) FROM the settling tank 7 to the sensor 3 is home. Upon completion of the emulsion circulation cycles through the sensor 3 of the moisture meter and registration of discrete values of humidity, the control unit 5 sends commands to open the shut-off elements 11–12 and turn on the emulsion supply pumps 6. When this emulsion from the tank 7 10 54 ends in the process pipe; Bypass, the locking element is designed for manual discharge of the emulsion if necessary. Upon completion of the injection of the emulsion from the settling tank 7 into the process pipeline 2, the control unit 5 commands the closing of the locking element 11, stops the emulsion supply pump 6 and opens the valve 9 The measurement of the humidity of the samples taken from the accumulator 7 is completed and the emulsion begins to enter the moisture meter 3. from conduit 2, and the secondary device k is switched on to measure the current value of its humidity. According to the registered moisture values taken from storage 7, probS, i),. G. and; „the dependence is determined, (t) and f (r), i.e., the dispersion of the emulsion is determined by the relative size distribution of water particles. Depending on the properties of the emulsion, its durability, you can change the program of the control unit 5, change the time intervals for switching on the pump 6 and the locking elements 10, 13 after closing the element 8 and the total number of measurement cycles. I Application of the invention allows for intensification (dehydration processes). oil due to the alternate determination of moisture and dispersion of emulsions with the same analyzer. Formula of the Invention A device for automatically measuring the parameters of water-oil emulsions containing a moisture meter sensor installed on the sampling pipeline and connected to the secondary device, which is distinguished by the fact that, in order to increase the efficiency of the device by increasing the range of determined parameters, it is equipped with a sample accumulator with inlet and outlet nozzles placed at different levels of the accumulator, shut-off elements installed on all lines of communication, and a control unit connected to the control inputs of all the locking elements, while the sensor input of the moisture meter is connected through the corresponding external elements with the upper and lower levels of the accumulator, and the output - with the average level - Sources of information taken into account during the examination of 1o Zakharchenko V.N.
