摘要: 在某千万吨级炼油厂生产国V排放标准清洁汽油过程中,进行了围绕S Zorb装置开展总体生产方案的优化研究。通过对催化裂化原料在不同加氢反应深度时,全厂氢气平衡、产品分布、汽油辛烷值等方面进行综合对比,确定S Zorb原料硫含量最优的控制范围, 全厂吨原油效益增加5.2元;通过优化调整S Zorb装置稳定塔的操作参数,在冬季回炼部分液化气,辛烷值损失减少0.3个单位;对S Zorb干气多种加工路线进行了对比测算分析,选择最合适的路线,每吨干气效益增加240元。

Abstract: To produce national V gasoline, the optimum scheme for the plant around S Zorb device was conducted. Through the comprehensive analysis of the hydrogen balance, product distribution as well as octane number, the optimal sulfur content in S Zorb feed was determined, making the benefit increase 5.2 Yuan RMB per ton crude oil. By optimizing the operating parameters of the S Zorb gasoline stabilization tower and recycling part of LPG in winter, the octane number loss reduces by 0.3. After optimizing processing routs for dry gas of S Zorb unit, the benefit increases 240 Yuan RMB per ton dry gas.

Key words: S Zorb, clean gasoline production, octane number, optimization of production plan
