FIELD: oil and gas industry.SUBSTANCE: invention pertains to oil and gas industry and it can be used for gas treatment at oil and gas condensate deposits in order to reduce capital and operational costs. Gas treatment installation is equipped with automatic control system (ACS) connected to shutoff and control valves including the first throttle valve at gas feed line, the second throttle valve installed at the line connecting primary and low-temperature separators, the third and fourth throttle valves installed at lines connecting outputs of primary and low-temperature separators for liquid-gas mixture respectively with degasifier, the fifth throttle valve installed at line of liquid discharge from degasifier and the sixth throttle valve installed at line of gas release from degasifier. The installation is equipped with the first flow metre at gas feed line and the second flow metre at line of gas discharge from low-temperature separator connected to ACS and having ability to regulate degree of opening and closure for the first throttle valve, temperature sensor at input of low-temperature separator connected to ACS and having ability to regulate degree of opening and closure for the second throttle valve, liquid level gage in primary and low-temperature separators and degasifier connected to ACS and having ability to regulate degree of opening and closure for the third. Fourth and fifth throttle valves respectively and pressure nozzle in degasifier connected to ACS and having ability to regulate consumption of inhibitor depending on pressure of gas in feed line or its flow rate. ACS uses software system for gas treatment regulation which includes regulation of process parameters in automatic mode.EFFECT: designing installation for primary treatment of gas supplied from gas wells in clusters that operates in unmanned mode due to use of software system for automatic regulation of gas treatment.1 dwg |
