Fu C., Gundersen T., 2015, Appropriate Placement of Compressors and Expanders in Above Ambient Processes, Chemical Engineering Transactions, 45, 643-648.
The appropriate placement of compressors and expanders is studied in this paper. Since both heat and work are involved, the topic is extended from heat integration to the integration of both heat and work. The objective is to minimize exergy consumption for the integrated processes. A set of theorems have been proposed for assisting the design. A graphical design methodology using the Grand Composite Curve is developed that achieves the target of minimum exergy consumption.
