摘要
通过对传统催化裂化装置增产柴油工艺中出现的问题进行分析、计算和试验,提出了分馏塔顶循环脱水技术,并在克拉玛依石化公司催化裂化装置上进行了工业应用。应用结果表明,顶循环脱水技术投用后,解决了分馏塔结盐问题,分馏塔顶温度可控制在93.3℃左右,汽油终馏点降至160.5℃左右,柴油初馏点降至146.0℃左右,不仅实现了大幅度增产柴油的目标,而且有利于节能。经过核算该技术产生的经济效益达到4626.632万元/a。
A method of anhydration of fractionator overhead recycle oil was proposed and applied to increase the yield of diesel oil based on the analysis of problems existed in FCC unit for increasing diesel fraction yield. The application results showed that the salt deposition in the main fractionation column was solved, the top temperature of the main fractionation column could be controlled to 93.3 ℃ ,and the dry point of gasoline fraction and the initial boiling point of diesel fraction were dropped to 160.5℃ and 146.0 ℃ ,respectively. Besides increase the yield of diesel oil the energy consumption of the unit was reduced,an economic benefit of 46.26 MRMB was obtained annually.
