Abstract: Changqing Gas Field has depended on import of the skid-mounted natural gas TEG dehydration unit for a long period of time. To change this unfavorable situation, the procedure and operational management of digital gas-gathering station (GGS) at Changqing Gas Field were analyzed with the efforts to optimize natural gas TEG dehydration process, install the advanced control system and innovatively develop the domestic-leading large-scale skid-amounted dehydration unit (200?04 -500?04m3 / d), further meeting the demand of gas field production and development. The main function of the unit include TEG dehydration, glycol regeneration, heating rectification, flashing, recycle, heat exchange and knock out. The construction period of the dehydration unit was reduced by more than 50 percent and land use reduced by more than by more than 30 percent. Large-scale application allowed investment to decline by more than 30 percent. Integration of the unit improved the technological level of skid while modeling of the unit raised installation quality, convenient for operation and maintenance.
