南充轻烃装置二次回收工艺技术研究

STUDY ON PROCESS TECHNIQUES OF SECOND RECOVERY IN NANCHONG NGL PLANT

摘要: 通过对南充轻烃回收装置现状分析，研究了影响该装置轻烃收率的主要因素，采用一新增分馏塔对膨胀机出口物流进行二次回收，有效地提高了装置的产品收率，日增产轻烃4吨左右。

Abstract: This paper analyzes main factor of influencing the product yield of NGL for Nanchong NGL plant.By adding a distillate tower,the stream from expander output is separated.The results show that NGL is increased 4 tons per day than before.
