摘　　要：在50~100 USD/bbl(1 bbl≈0.133 t,以布伦特原油为基准)的国际原油价格下,对中间基沙特轻质原油-沙特重质原油(沙轻-沙重)的混合原油减压蜡油的不同加工方案进行了模拟研究,考察了流化催化裂化(FCC)、催化裂解(TMP)、催化柴油加氢-催化裂解(加氢-催化裂解,HTMP)和加氢裂化(HCR)对CO2排放、柴/汽比、基本化工原料和高价值产品收率等技术指标的影响,并进行了经济效益对比分析。结果表明:当原油价格处于中低价位(<80 USD/bbl)时,采用产物分布中丙烯和高辛烷值汽油的收率之和高达60%的加氢-催化裂解方案可以降低柴/汽比,实现最短的资金回收周期;对于炼化一体化项目,采用加氢裂化方案可以获得最高的基本化工原料和高价值产品收率,当原油价格在中高价格(>80 USD/bbl)范围内,采用HCR方案可以提高装置的经济效益和抗油价波动能力。Impacts of medium-based vacuum gas oil processing routines on CO 2 emission,ratio of diesel and gasoline,yield of chemicals and high value products at international oil price of 50-100 USD/bbl were systematically studied.In addition,economic benefit analysis was also performed.Processing technologies include fluid catalytic cracking(FCC),two-stage riser catalytic cracking for maximum propylene(TMP),hydrogenation and catalytic cracking coupling process(HTMP)and hydrocracking(HCR).When crude oil is at middle/low price,analysis results show that HTMP processing strategy,from which the yield of propylene and high octane number gasoline could be up to 60%,can get products with low diesel/gasoline ratio and quick investment return.However,at middle/high crude oil price,HCR processing strategy,from which the yield of chemical raw materials and added-value products is high,can help integrated refining and petrochemical plants to reach maximum economic benefit under fluctuated oil price environment.
