Exergy analysis of Fischer-Tropsch synthesis unit apparatus during coal indirect liquefaction
摘要
Abstract
Based on the PRO/ II simulation and optimization results of low temperature Fischer-Tropsch synthesis (FTS) system, the exergy thermodynamic analysis was applied to calculate the exergy distribution of Fischer-Tropsch synthesis system. The exergy efficiency and exergy losses of this system were also analyzed. The results show that FTS reaction process is the largest exergy loss process. The equipment with the maximum exergy loss is FTS reactor,with exergy efficiency 86. 80% , sharing 85. 15% of total exergy loss;the condensate backflow pump has the lowest exergy efficiency,which is only 6. 71% ;the exergy efficiencies of wax collection tank,wax pump and wax intermediate tank are the highest, which have no exergy loss nearly. By using exergy analysis method, it can be more accurate and convenient to uncover the process and devices with the maximal exergy loss, which can set up the target and provide suggestions for equipment improving and energy saving.关键词
