cryogen

A series of quenching oils,such as quick,quick & bright,vacuum,isothermal & graded quenching oils,was developed through investigating cooling accelerant and brightener,then selecting premium additives and packing.

通过对催冷剂、光亮剂等添加剂的考察,筛选出性能优良的新型添加剂并复合,研制出满足SH 0564-93指标要求的快速淬火油,快速光亮淬火油,1#、2#真空淬火油,1#、2#等温分级淬火油。

In order to improve the NGL recovery rate for some condensate gas fields, which had high pressure gas source and there was no differential pressure for utilization, this paper put forward a cryogen refrigeration-oil absorption combination process to recover NGL on the basis of cold oil absorption theory.

为了进一步提高天然气凝液装置的产品收率,本文针对凝析气田中气源压力高,无压差可利用的工况条件,应用冷油吸收原理,通过工艺流程模拟分析与研究,确定了冷剂制冷-油吸收复合凝液回收工艺原理流程。
