【摘要】：在炼油化工一体化生产形势下,结合汽油、柴油质量升级要求和新的催化烟气排放标准,中国石油化工股份有限公司武汉分公司优化了生产流程。在优化乙烯原料的前提下,将部分加氢裂化尾油作为催化原料,并将2号催化柴油作为蜡油加氢装置原料,提高了催化加工负荷及汽油产量;根据催化稳定汽油硫含量选择汽油加氢工艺路线,降低了汽油辛烷值的损失,实现了汽油加氢装置长周期生产;优化CO锅炉操作,适应催化烟气脱硫、脱硝的运行要求,消除了提高催化加工量的瓶颈。2015年,在原油加工量同比下降181.0 kt的情况下,催化原料增加了62.9 kt,催化汽油产量增加了64.5 kt,催化柴油减少了194.4 kt,加氢柴油增加了78.1 kt,经济效益达3 683.1万元。
[Abstract]:Under the situation of integrated production of oil refining and chemical industry, the production process has been optimized by Wuhan Branch of China Petrochemical Co., Ltd., in combination with the requirements of gasoline and diesel quality upgrading and the new catalytic flue gas emission standard. On the premise of optimizing ethylene feedstock, partial hydrocracking tail oil was used as catalytic feedstock, and No. 2 catalytic diesel oil was used as feedstock for wax oil hydrogenation unit, which increased the catalytic processing load and gasoline output. According to the sulfur content of catalytic stabilized gasoline, the process route of gasoline hydrogenation is selected, the loss of gasoline octane number is reduced, the long period production of gasoline hydrogenation unit is realized, and the operation of CO boiler is optimized to meet the operational requirements of catalytic flue gas desulfurization and denitrification. The bottleneck of increasing catalytic processing capacity has been eliminated. In 2015, the crude oil processing volume decreased by 181.0 kt compared with the same period last year, Catalytic feedstock increased 62.9 kt, catalytic gasoline production increased 64.5 kt, catalytic diesel decreased 194.4 kt, hydrogenated diesel increased 78.1 kt, economic benefit reached 36.831 million yuan.
