CHP generation in heat integrated separation system

Abstract

Paper presented at the 7th International Conference on Heat Transfer, Fluid Mechanics and Thermodynamics, Turkey, 19-21 July, 2010.This paper presents an industrial case-study: the synthesis of heat-integrated distillation systems applied to the light ends separation section of olefin and gas process plants. Io this paper, the possibility of producing power in a sequence of heat integrated columns in a chemical process is inspected. The aim is to find the best sequence with heat integration and its feasible power production as a means of achieving a minimum TAC (Total Annual Cost). First, all sequences have been simulated with HYSYS aod then, heat integrations and feasible power production in each sequence are examined. After finding the best values for parameters of each sequence, all sequences are compared and finally the optimum state for the process is found.
