| 摘 要： | 为使中国汽油达到欧V汽油的含硫标准,研究蒸馏脱硫工艺的可行性有实际意义。以甲基叔丁基硫醚为关键含硫组分,使用Aspen Hysys v 7.0模拟其与MTBE分离过程。按MTBE单塔蒸馏、双塔能量集成蒸馏和与分馏塔能量集成3种方案脱除硫化物,进料硫化物含量100μg/g的条件下,塔顶MTBE含硫化合物1μg/g,3种方案吨产品蒸汽消耗分别为0.233t、0.13t和0.08t。MTBE中含硫化合物与MTBE容易分离,简单精馏可以实现深度脱硫。双塔能量集成方案比单塔直接分离方案节水50%,节约蒸汽45%。MTBE脱硫塔与MTBE分馏塔或催化蒸馏塔进行能量集成,不增加冷却水,蒸汽消耗每吨MTBE增加小于0.1t。辅助塔可以使硫化物浓缩到99%(m/m),MTBE含硫化物30μg/g,可以混兑低硫产品中或循环回分离系统,MTBE几乎无损失。

| Abstract: | To reach the Euro V fuel standard in terms of sulfur content,the study of the feasibility of desulfunzation process by distillation was of practical value in China.MTBE desulfurization by distillation was simulated by Aspen Hysys v 7.0,with tert-butyl methyl sulfide as the key sulfur containing compound.Three cases were simulated with regard to one-column simple distillation,two columns at different pressure with energy integration configuration,and high pressure distillation integrating energy with MTBE se... |
