摘要
面对炼油产能严重过剩的局势,炼油向烯烃、芳烃等基本化工原料转型已成为行业发展的必然趋势。针对某炼厂生产现状,从全厂总流程角度出发设计了该炼厂的化工转型方案,致力于解决炼厂蜡油不平衡及成品油过剩的问题,主要利用“加氢裂化+催化裂解”组合工艺设计转型升级方案。转型升级后,原油加工总量增加了50 t/a,但与炼厂现状相比,成品油产量降低,高附加值化工产品产量增加,且汽柴油收率由57.75%降低至31.79%,而化工品由3.39%提高至24.11%。
As the glut of refined oil products continues to aggravate the serious refining overcapacity,shifting the focus from oil products to basic chemicals such as olefins and aromatics has become the mainstream of the refining industry.The"shifting to chemical"scheme was designed for a refinery in line with its current conditions and overall prosesses by upgrading the combined process of"hydrocracking plus catalytic cracking",to tackle the problem of unbalanced VGO processing and excess oil products.Thus the refinery reduced oil products output and increased highvalue chemicals output,despite adding throughput by 500 kt/year.The yield of gasoline and diesel decreased from 57.75%to 31.79%,while the yield of chemicals increased from 3.39%to 24.11%.The refinery achieved the goal to maximize chemicals output.
