Summary
Aims of the course are following: 1. to give systematic overview of computer aided methods for processes and modeling in chemical technology. 2. to allow practical application in the field of software Aspen Engineering Suite. Course is referring to Process engineering, Unit operation, and Physical chemistry courses. In the frame of the course general problems of heat, momentum and mass transfer will be located to realistic unit operation and solved using sophisticated modeling software. Graduate will be able to orient himself in processes simulation field; will be able to work with relatively complicated software; will be able to treat simple technological processes and provide optimization and parametric study independently.
