Prime—G＋汽油加氢技术改造30万t／a柴油加氢装置

摘要

山东恒源石油化工股份有限公司采用AXENS公司的Prime—G＋催化裂化汽油固定床选择性加氢脱硫处理技术，对30万t／a柴油加氢装置进行改造。在充分利用现有资源的基础上，增加了导热油系统、全馏分选择性加氢（SHU）反应分馏系统及循环氢脱硫系统。改造工艺选用AXENS公司的选择性加氢催化剂HR-845、HR-806和R-841，在保征脱硫水平的同时，使辛烷值损失最低，完全满足汽油硫质量分数不大于50μg／g、辛烷值损失不大于1．5设计指标的要求。%Shandong Hengyuan Petrochemical Company Limited used French company AXENS＇ Prime - G＋ fixed -bed selective hydrogenation desulfurization technology to reinforce 300kt/a diesel hydrodesulfurization unit. Based on available resources, heat -conducting oil system, full -range selective hydrodesulfurization fractionation system, and circulating hydrogen in benzol hydro -refining system were added. The reformed technology used HR -845, HR- 806, and R- 841 selective hydrogenation catalyst of AXENS company and produced gasoline meeting National 1V Emission Standards.
