Process integration (heat exchanger networks) using Pinch analysis.

Training goas: Hot and cold streams have an special role in industrial processes, such as promoting reactions or separation of mixtures of commercial interest. The hot and cold streams reuse has great potential for application because of substantial return of investment when applied to chemical processes. In this context, the aim of this course is to present the Pinch method for heat and cold streams integration, with practical applications and critical evaluation of the results. Throughout the course, students will have not only an overview of the methodology, its limitations and potential applications, but also specific details by solving exercises.

Prerequisites: The course is intended to chemical or mechanical engineering with skills in   spreadsheet software. 

Remarks: Audio or video recording or broadcasting is forbidden.
