中石油大庆石化公司炼油厂2008年140×104t/a新延迟焦化装置建成和2009年一套重油催化裂化装置完成MIP改造造成液化石油气的产量大幅增加。为适应这一变化,气体分馏装置采取了(1)气分装置与催化装置的热联合技术改造(2)脱丙烷塔、脱乙烷塔与精丙烯塔的塔盘改造(3)精丙烯塔增设一台釜罐与两台塔顶冷凝器的改造措施:装置的加工量扩大到17.07×104t/a,节能降耗效果显著,产品收率得到提高。
PetroChina Daqing Petrochemical Company refinery 2008 140 × 104t / a new delayed coking unit built in 2009 and a set of heavy oil catalytic cracking unit to complete MIP reform resulted in a substantial increase in the production of liquefied petroleum gas. In order to adapt to this change, the gas fractionator adopts (1) thermal combined reforming of the gas distribution unit and the catalytic unit (2) Tray modification of the depropanizer, deethanizer and fine propylene reactor (3) The addition of a kettle tank and two overhead condenser retrofit measures: the processing capacity of the device expanded to 17.07 × 104t / a, energy saving effect is significant, product yield is improved.
