摘要甲醇（MeOH）和甲基叔丁基醚（MTBE）的分离是化工行业中最具挑战性的过程之一。基于膜的渗透蒸发是分离甲醇-MTBE等共沸和近沸混合物的有吸引力的替代方案。另一方面，常规方法，例如蒸馏，尽管在许多工业中是可行的和使用的，但伴随着高的资本和操作成本，从而使得分离方法复杂。渗透汽化（PV）是一种可行的替代共沸蒸馏从经济和技术的观点。作为一种清洁技术，这种膜分离过程为一些环境问题提供了解决方案。虽然基于PV的混合工艺引起了工业界的关注，但MeOH/MTBE的PV分离进展表明，该技术可以处理更大份额的这种特定分离。本文综述了甲醇/甲基叔丁基醚体系的性质、生产及分离工艺。着重介绍了用于分离的不同PV膜的性能，并对未来的膜材料进行了展望。
Abstract Separation of Methanol (MeOH) and Methyl‐tert‐butyl ether (MTBE) is one of the most challenging processes in the chemical industry. Membrane based pervaporation is an attractive alternative to separate azeotropic and close‐boiling mixtures like Methanol‐MTBE. Conventional process, such as distillation, on the other hand, although feasible and in use in many industries, is accompanied by high capital and operating costs thereby rendering the separation process complex. Pervaporation (PV) is a viable alternati`ve to azeotropic distillation both from economical and technical viewpoints. As a clean technology, this membrane separation process has provided solutions to several environmental problems. While PV‐based hybrid processes have attracted industrial attention, progresses in PV separation of MeOH/MTBE suggest that this technique can handle a greater share for this particular separation. In this paper, an extensive review on the properties, production, as well as separation processes utilised for methanol/MTBE system is presented. The performance of different PV membranes applied for this separation is highlighted and emphasis on prospective membrane materials for the future is laid.
