常减压装置减压深拔工艺探讨

为了多加工低价的重质原油同时提高减压蜡油收率,增加经济效益,应考虑减压深拔。简要介绍了KBC和Shell两公司减压深拔技术的特点,结合国内外减压深拔的实际操作情况,从工艺和设备两方面,分析和讨论了影响拔深的主要因素。

Discussion on Deep Cut Technology for Atmospheric and Vacuum Distillation Unit

In order to process more cheap heavy crude and increase economic benefit while taking the restraint of the limited processing capacity of delayed coking unit into consideration,it is necessary to reduce the yield of vacuum residue and increase the yield of VGO,and therefore deep cut technology must be considered.This paper introduces the features of the deep cut technologies of KBC and Shell, and analyzes the effect of heating furnace structure and steam injection rate,structure and temperature drop of high...
