由中国石油集团工程设计有限责任公司西南分公司设计的川中油气矿秋林轻烃回收站工程 ,经过几个月的试运行 ,装置运行平稳 ,经考核各项指标均达到设计要求。根据现场实际情况 ,该工程采用了先膨胀 ,后增压的工艺流程。为最大程度提高Ｃ3收率 ,降低装置能耗 ,工艺设计中借鉴国内 Designed by CNPC Engineering Design Co., Ltd. Southwest Branch of the Chuanzhong oil and gas QiuLin light hydrocarbon recovery project, after several months of trial operation, the device runs smoothly, after the assessment of the indicators have reached the design requirements. According to the actual situation on site, the project uses the first expansion, after pressurization process. In order to maximize the yield of C3, reduce the energy consumption of the device, draw lessons from the domestic craft
