CNG加气母站增产改造方案的比选

Comparison and Selection of Schemes for Capacity Expansion of CNG Refueling Station

针对中国石化吉林石油分公司大岭CNG加气母站冬季供气量不能满足需求的情况,进行了保供增产方案的研究,对比分析了增加2台三级压缩机和2台一级变频管道增压机两种方案在生产能力、投资费用以及工艺运行效果的特点,结果表明,增加2台三级CNG压缩机的方案更适合大岭加气母站的增产改造要求。

According to the supply shortage situation of the SINOPEC Jilin Oil Products Company Daling CNG Refueling Station,investigation on the capacity expansion schemes was carried out. The characteristics of the two schemes,addition of three-stage compressor or installation of one-stage pipeline supercharger,were compared and analyzed from the aspects of production capacity,investment cost,and process operation performance. The results showed that installation of 2 three-stage compressors was more suitable for the requirements of capacity expansion of the Daling CNG Refueling Station.
