Heat Consumption and Irreversibilities in Rectification Processes

摘要

Chemical engineering analysis using entropy production has been proven to be an essential tool to identify areas in chemical plants, where degradation of energy occurs. Though, applied very extensively in the area of heat exchanger networks in the form of "pinch technology" , the method is rarely used with respect to processes with mass exchange. Entropy productions in destination columns have been evaluated and discussed with respect to feed introduction, sequences of columns and other technically important features.
