FIELD: oil and gas industry.
SUBSTANCE: invention relates to collection and processing of natural hydrocarbon gas by absorption drying, and can be used in processes of field preparation for transportation of gas deposits products. Method of preparing hydrocarbon gas for transportation includes separation of gas of distant well clusters, introduction of regenerated absorbent in gas stream after separation, removal of moisture-saturated absorbent from gas flow, transportation of gas for further preparation together with gas of close well clusters, separation of gas from close well clusters, introduction of regenerated absorbent in gas stream after separation, removal of moisture-saturated absorbent from gas flow, introduction of gas flow previously separated gas to remote well clusters, separation of mixed gas compression and cooling in two stages of mixed gas introduction into gas stream of regenerated absorbent, removal from gas flow saturated absorbent for regeneration, cooling of mixed gas and its output from the installation, wherein dew point temperature of transported gas is provided below temperature of transported gas by 7-12 °C.
EFFECT: invention provides single-phase transportation of gas and reduced consumption of methanol.
