METHOD OF TREATING NATURAL AND ASSOSIATED OIL GAS FROM SULPHURIC COMPOUNDS AND FACILITY FOR IMPLEMENTATION OF THIS METHOD Russian patent published in 2009 - IPC B01D53/14 

FIELD: oil and gas industry.

SUBSTANCE: upon dehydration and scrubbing of solid particles in filter 1 source gas is compressed in compressor 2, further it is cooled in heat exchanger 3 and directed to absorption into device 4. Section of the inlet nozzle of device 4 is made so, as to facilitate rate of gas within ranges of 650-700 m/sec and vacuum of value 0.005-0.007 MPa (abs) for creating a turbulent mode and for intensifying absorption process. In section of an outlet from the vacuum cavity nozzle rate of gas is maintained within ranges of 180-250 m/sec, also pressure is raised to 1.5 MPa. Simultaneously under influence of pressure drop alkaline water is supplied into the vacuum cavity from an electrolytic cell 8; this water is preliminary purified via magnet device 12 with induction of 0.2-03 tesla. Steam-gas mixture created in device 4 is cooled in heat exchanger 5 with circulation water and is directed to separation in vortex separator 6. Treated gas is sent to further processing, while separated water is regenerated in desorber 14.

EFFECT: increased efficiency of coefficient of mass transfer at contact of treated gas and absorbent, reduced mass-dimension characteristics of device and reduced costs per unit.
