METHOD FOR ADDITIONAL DRYING AND PURIFYING OF HYDROGEN-SULPHIDE-CONTAINING ASSOCIATED GAS FOR FURTHER USAGE AS FUEL IN GAS GENERATOR PLANTS AND SYSTEM FOR ITS IMPLEMENTATION Russian patent published in 2015 - IPC B01D53/52 C10L3/10 

FIELD: oil and gas industry.

SUBSTANCE: method for additional drying and purifying of hydrogen-sulphide-containing associated gas for further usage as fuel in gas generator plants includes delivery of pre-separated gas under pressure of 0.05MPa to modular compressor station (5) for gas compressing and cooling. Then compressed gas under pressure of 0.52MPa is sent to gas-separating receiver (3) for additional drying upon compressing and cooling. Then gas is purified from mechanical impurities by series gas-treatment filter (6, 7). Purified and dried gas is delivered to modular power generating stations based on microturbines (4) for the purpose of its final usage. The system for associated gas drying and purifying contains in-series container doe separated associated gas (E-3), condensate tank (2), modular compressor station (4), gas-separating receiver (3), at least two series gas-treatment filters from mechanical impurities (6, 7) and at least two modular power-generating stations (4).

EFFECT: increased efficiency of associated gas drying and purifying.
