摘要:
采用PHF-101和PHF-151催化剂在中国石油云南石化有限公司280万t/a柴油加氢装置上进行工业应用，分析了装置长周期运行中存在的问题，并提出解决措施。结果表明：在PHF-101催化剂运行末期，精制柴油产品闪点偏小，通过将汽提塔压力从1.00 MPa降至0.87 MPa后，产品闪点从60 ℃提高至65 ℃；在加工高含硫原油生产的混合柴油原料期间，精制柴油产品含硫量偏高，通过优化原料油组成，将常三线柴油加工比例从45.2%降至40.0%，产品含硫量从19.4 μg/g降至12.1 μg/g；在加工量235 t/h、平均反应温度379 ℃的条件下，将反应器入口压力从6.2 MPa升高至6.5 MPa后，产品含硫量从16.2 μg/g降至10.7 μg/g，但是新氢消耗量增加了3.7 m3/t。
Abstract:
Industrial application of PHF-101 and PHF-151 catalysts was carried out in a 2.8 Mt/a diesel hydrogenation unit of Yunnan Petrochemical Co Ltd of PetroChina. The existing problems during the long-term operation of the unit were analyzed， and solutions were proposed. The results showed that at the end of the operation of PHF-101 catalyst， the flash point of refined diesel product was relatively small. By reducing pressure of stripping tower from 1.00 MPa to 0.87 MPa， the flash point of the product increased from 60 ℃ to 65 ℃. During processing of mixed diesel produced from high sulfur crude oil， refined diesel product had a relatively high sulfur content. By optimizing composition of the raw oil， the blending ratio of third atmospheric distillation sideline diesel was reduced from 45.2% to 40.0%， and the sulfur content of the product was reduced from 19.4 μg/g to 12.1 μg/g. Under the conditions of a processing capacity of 235 t/h and an average reaction temperature of 379 ℃， when increasing the inlet pressure of reactor from 6.2 MPa to 6.5 MPa，the sulfur content of the product was decreased from 16.2 μg/g to 10.7 μg/g. However， the consumption of new hydrogen was increased by 3.7 m3/t.
