The aim of this project is to simulate different membrane processes to develop rules of thumb for conceptual design of membrane processes. The student in this project will learn how to use the software Aspen Plus®, a wide used software in petrochemical industry, to simulate the membrane process for the separation of propylene and propane. Through this project, the student will learn all the basic knowledge of membrane processes, understand the reason why gas separation is so important in chemical industry and what are the advantages and challenges in the membrane studies. The education aim of the project is to stimulate the interest of the student in membrane studies.
