UNIT FOR PREPARATION OF HYDROCARBON GAS FOR TRANSPORTATION Russian patent published in 2007 - IPC C10G5/06 F25J3/08 B01D53/26 

FIELD: gas, petrochemical and other industries.

SUBSTANCE: proposed unit includes the following components connected in succession by gas route: intake separator 1, scrubber 3, first compression stage 4, air cooling apparatus 5, intermediate separator 6, gas high drying set 7, second compression stage 8, second air cooling apparatus 9 and second intermediate separator 10. Gas outlet of second intermediate separator 10 is connected with gas and condensate transportation pipe line and with inlet of fuel gas preparation set 11 of gas-turbine drive. One outlet of preparation set 11 is connected with inlet for delivery of fuel gas to gas-turbine engines and second outlet is connected with inlet for delivery of reactivation gas to gas high drying set 7. Pipe line for escape of reactivation gas from gas high drying set 7 is connected with delivery pipeline of first compression stage 4 in front of air cooling apparatus 5. Proposed unit makes it possible to improve quality of gas and condensate by water dew point during preparation for transportation.

EFFECT: high degree of cleaning gas from toxic admixtures; increased service life of compressor equipment; reduced capital outlays; improved quality of gas and condensate.
