柴油加氢装置扩能改造及分子筛料和清洁柴油试生产

为扩大产能并实现分子筛料和清洁柴油生产,中国石油化工股份有限公司金陵分公司对140万t/a柴油加氢装置进行了技术改造。将催化剂更换为FHUDS-2深度加氢脱硫催化剂;新增1套分馏系统。改造后,分子筛料产率可达15%以上。在改造后的装置上可同时生产分子筛料和硫质量分数小于50×10-6的清洁柴油,但反应器入口温度提高31℃,加工能力降低20 t/h。

Revamping for capacity expansion of diesel hydrogenation unit and trial production of molecular sieve dewaxing feedstock and clean diesel oil

In order to expand production capacity and to produce molecular sieve dewaxing feedstock and clean diesel oil,a 1.4Mt/a diesel hydrogenation unit was revamped in Jinling Petrochemical Company,SINOPEC.A deep hydrodesulfurization catalyst FHUDS-2 was used to replace the old one,and a new fractionation system was built up for producing the new products.After the revamping,the yield of molecular sieve dewaxing feedstock could reach more than 15%,and both the molecular sieve dewaxing feedstock and the clean dies...
