Method and system for compressing and dehydrating wet natural gas produced from a low-pressure well using a rotary screw compressor. A dehydrating agent is combined with wet natural gas within a rotary screw compressor. Operation of the rotary screw compressor causes compression and dehydration of the wet natural gas to produce a compressed dry natural gas. Engine exhaust produced by the engine which powers the rotary screw compressor may be used to remove water absorbed by the dehydrating agent and thereby recover the dehydrating agent for re-circulation in the system.
