摘　　要：以某炼化公司240万t/年的柴油加氢装置中循环氢脱硫系统的工艺为基础,进行Aspen Plus软件的工艺模拟,模拟参数与生产参数对比,其相对误差最大4.1%,在误差允许范围内,表明该模型能较好说明实际生产情况。通过该模型,对循环氢脱硫系统进行优化,研究了贫胺液进塔温度、吸收液浓度和溶剂流量等因素对脱硫效果的影响。结果表明:贫胺液进塔温度从生产时的48℃优化到44℃,循环氢出塔H_(2)S摩尔分数为1.544×10^(-5);吸收液质量分数优化在30%,循环氢出塔H_(2)S摩尔分数为1.195×10^(-5);溶剂流量增至原来的33%,循环氢出塔H_(2)S含量只减小2%。The Aspen Plus software is simulated based on the process of circulating hydrogen desulfurization parts in a 2.4 million tons/year of diesel hydrogenation device for a refinery company.The simulation parameters are compared with production parameters.The relative error is 4.1%at most.Within the allowable range,it indicates that the model can better explain the actual production situation.Through this model,the circulating hydrogen desulfurization section is optimized,and the effects of the poverty-stricken tower inlet temperature,the concentration of absorbing liquid,and solvent flow on the desulfurization effect is studied.The results show that the tower temperature of lean amine solution is optimized from 48℃to 44℃at the time of production and the H_(2)S content of circulating hydrogen outlet tower is 1.544×10-5.The concentration of absorption solution is optimized at 30wt%.The H_(2)S content of circulating hydrogen outlet tower is 1.195×10^(-5).When increasingthe solvent flow rate by 33%,the H_(2)S content of circulating hydrogen outlet tower only decreases by 2%.
