RSDS-Ⅲ全馏分加氢技术在低氢油比工况下的工业应用
|
摘要
中国石油化工股份有限公司广州分公司原300 kt/a焦化汽油加氢装置采用RSDS-Ⅲ全馏分加氢技术,在循环氢脱硫系统改造后,用于催化裂化汽油加氢,产品经过脱硫后生产国Ⅴ汽油调合组分。标定结果表明,改造后将催化裂化汽油硫质量分数从213μg/g降至6. 9μg/g时,辛烷值RON损失仅为0. 8单位,液体收率达到99. 7%以上,装置处理量可以达到268 kt/a,完全可以满足生产国Ⅴ(硫质量分数不大于10μg/g)清洁汽油的需要。说明RSDS-Ⅲ全馏分加氢技术具有较好的脱硫活性和较高的选择性。
The 300,000 TPY coker gasoline hydrotreating unit in SINOPEC Guangzhou Company was revamped by applying RSDS-Ⅲ full-range fraction hydrotreating technology. At the same time,the recycle hydrogen sweetening system was also revamped to produce FCC gasoline. The blending components of gasoline Guo Ⅴ standard are produced. The performance tests show that the sulfur content of FCC gasoline can be reduced from 213 μg/g to 6. 9 μg/g; The product octane loss is only 0. 8 units,the total yield of liquids is over99. 7% and operation capacity has reached 268 kt/a,which have fully met the requirements for the production of Guo Ⅴ clean gasoline. It shows that the RSDS-Ⅲ full-range fraction oil hydrogenation technology offers a higher desulfurization activity and a higher selectivity.
