英文摘要	an industrial scale dehydration process based on hollow fiber membranes for lowering the dew point of natural gas is described in this paper. a pilot test with the feed flux scale of 12x10(4) nm(3)/d was carried out. dew points of -8 degreesc-13 degreesc at a gas transport pressure in the pipeline of 4.6m pa and methane recovery of more than 98% were attained. the water vapor content of the product gas could be maintained around 0.01 vol% during a continuous run of about 700 hours. the effects of feed flux and operation pressure on methane recovery and water vapor content were also investigated. additionally, some auxiliary technologies, such as a full-time engine using natural gas as fuel and the utilization of vent gas in the process, are also discussed. a small amount of the vent gas from the system was used as a fuel for an engine to drive vacuum pumps, and the heat expelled from the engine was used to warm up the natural gas feed. the whole system can be operated in a self-sustainable manner from an energy point of view, and has a relatively high efficiency in the utilization of natural gas.
