摘要：

The decreases in fossil fuel reservoirs, along with several recent environmental crises of pollutants emission, have caused us to find more efficient methods for reducing energy consumption. Exergy analysis is the procedure of finding and improving the less exergetically efficient devices in a process. In this paper, exergy analysis of dimethyl ether production from methanol is investigated. It is observed that main lost work in the process takes place in the shell and tube heat exchangers. Thus, it is proposed to replace the two heat exchangers with an LNG heat exchanger. It is shown that preheating the streams in the LNG associated with a shell and tube heat exchanger reduces 97% and 54% of the lost work for those two heat exchangers.
