Abstract

The global energy crisis and continued reliance on fossil fuels highlight the urgent need for sustainable alternatives. Dimethyl ether (DME) has emerged as a promising low carbon fuel owing to its clean combustion properties and versatility as an LPG substitute, diesel replacement, and chemical feedstock. This study focuses on optimizing the design of DME production from syngas derived methanol, with particular emphasis on conversion efficiency and thermal management. Base case simulations revealed that higher methanol dehydration conversion elevated reactor temperatures by nearly 100 °C, thereby disrupting equilibrium and hindering effective separation. To address these challenges, a modified process integrating cooling, heating, and distillation units was developed, achieving an 80% conversion and a DME yield of 97.6%, while simultaneously reducing excessive cooling requirements. These findings demonstrate that improved thermal control and separation strategies can significantly enhance both energy efficiency and environmental performance, reinforcing DME’s potential role in the transition toward cleaner energy systems.
