| Abstract: | A water vapor removing process based on membrane technology was developed to decrease the dew point of natural gas. A pilot test with a feed flux of 12 × 104 m3/d was carried out. The effects of feed flux and operation pressure on the dehumidification process were investigated. The dew point of the dehumidified gas was -8～ 13 ℃ under a gas transportation pressure of 4.6 MPa. A recovery of more than 98% of methane was achieved. Related technologies such as the utilization of vent gas for driving natural gas engine were also discussed |
