ASSOCIATED GAS TREATMENT METHOD Russian patent published in 2013 - IPC E21B43/40 

FIELD: oil and gas industry.

SUBSTANCE: method involves use of turbocompressor unit with low and high pressure stage, filter separator for removal of gas from condensate, water and mechanical impurities, which are installed before low pressure stage, and after low pressure stage - gas air cooling unit, separator for removal of gas from liquid with gas inlet, gas outlet and liquid outlet connection pipes, intermediate and end gas air cooling unit that is installed after the first and the second stages of high pressure, intermediate and end separators for removal of gas from liquid with gas inlet, gas outlet, condensate and water outlet connection pipes. According to the invention, the use of additional gas air cooling unit is provided, which is connected in series to outlet of gas air cooling unit located after intermediate separator of high compression stage of turbocompressor unit, and additional pump by means of which mixed flow of condensate and paraffin formation inhibitors is supplied via the pipeline to new supply assembly of condensate and inhibitor of hydrate formation between in-series connected gas air cooling units.

EFFECT: increasing operating efficiency of wells operated by means of gas-lift method due to avoiding condensation of hydrocarbons by means of additional removal of heavy hydrocarbons from oil gas at compressor station.
