Objectives

Students are expected to acquire theoretical and practical skills on process modeling and optimization in chemical enginnering and related areas. The course has a strong practical component based on the intensive use of two commercial software packages (gPROMS and Aspen Plus) for process simulation and optimization, which are widely spread in the chemical industry.

Teaching method

In lectures concepts are illustrated through the use of transparencies and slides. In laboratory sessions students solve process simulation and optimization problems by using the process software available for teaching at the department. Many concepts are elaborated through the presentation and discussion of case studies.
