Synthesis Of Mass Exchanger Network Considering Piping And Pumping Costs Using Process Integration Principles
Journal Title: Journal of Chemical Engineering & Process Technology - Year 2017, Vol 8, Issue 1
Abstract
This paper presents a procedure to optimize mass exchanger network considering piping and pumping costs. This optimization technique is based on the combination of Pinch technology with mathematical programming approach to obtain the optimum minimum allowable composition difference (ε) value. In the present work three examples are taken from open literature to study the contribution and effect of piping and pumping costs on optimum ε value and mass exchanger network design. The results obtained for Examples 1, 2 and 3 shows that ε changes from specified to optimized ε value with improved network configuration before considering piping and pumping costs. After accounting piping and pumping costs ε changes from optimized to new optimized ε value with the changes of network configuration. Further, based on results of Examples 1, 2 and 3 it is found that piping and pumping costs contributes around 12% and 3% towards TAC of a mass exchanger network.
