摘　　要：提出了三种从费托合成油品中脱酸和含氧化合物工艺.借助Aspen Plus模拟软件对三种工艺进行了优化设计,并对三种工艺的优劣进行了比较.结果表明,萃取精馏法工艺比较复杂;共沸精馏法在工艺上比萃取精馏法简单,而且达到同样的分离目标所需的工艺条件温和,节约了成本;非均相共沸精馏与均相共沸精馏相比,所需的溶剂比较低,而且溶剂回收更容易实现,从而降低了成本,但是,非均相共沸精馏的缺点在于其溶剂回收率不如均相共沸精馏高.Three technologies of removing acids and oxygenates from oil of Fischer Tropsch synthesis were developed. The advantages and disadvantages of these technologies were compared by Aspen Plus simulation software. The results show that the azeotropic distillation process is easier than extraetiye distillation process. Because of its milder process parameters, the equipment cost is lower. Compared with homogeneous azetropic distillation, the ratio of solvent to feed is lower, and the solvent can be recovered easily. But the recovery ratio of solvent for hete- rogeneous azetropic distillation is lower than that for homogeneous azetropic distillation.
