Process Simulation of Dimethyl Ether Synthesis from Methanol Using Honeywell UniSim Design R490

Abstract: Implementing dimethyl ether in order to blend in LPG has led to remarkable profits. The present work focuses on the simulation of the synthesis of dimethyl ether from methanol using Honeywell's UniSim Design R490. Dimethyl ether is considered a green energy source as an additive for diesel fuel. This is preferred for the next clean energy production, and dimethyl ether is chosen because its demand is increasing due to its remarkable properties. The indirect method of producing methanol and using it as a raw material for the synthesis of DME is quite useful for large commercial production. However, current work will demonstrate methanol as a feed and dimethyl ether as an end product. Shell and tube heat exchanger at different operation conditions show that important calculated LMTD and minimum approach values are feasible for good heat transfer while minimizing power consumption.
