TL;DR
A new microwave process for producing ethylene from methane is found to be economically competitive and more energy-efficient than traditional methods.
Contribution
The study introduces and evaluates an industrial-scale microwave process for ethylene production, demonstrating its economic and environmental advantages.
Findings
The microwave process has a lower levelized cost of ethylene (USD 0.51/kg) compared to conventional methods (USD 0.56/kg).
The process consumes mostly electricity, supporting the electrification of chemical manufacturing.
The study confirms the economic feasibility of microwave reactors and modular plant configurations.
Abstract
Ethylene is a critical feedstock in industrial processes, serving as a raw material in the petrochemical industry to produce plastics and commodity chemicals. Conventional ethylene production routes are energy-intensive and contribute substantially to the carbon footprint of chemical manufacturing. In this study, an industrial-scale novel microwave process was simulated using ASPEN Plus to assess its economic viability. Technoeconomic analysis confirmed the economic competitiveness of the novel microwave process, with a levelized cost of ethylene of USD 0.51/kg compared to USD 0.56/kg for the conventional base case. Key economic drivers of the process were identified, and sensitivity analyses were conducted to evaluate their impact on project economics. Furthermore, 87.7% of the total utility consumption in the novel microwave process is electricity, highlighting its potential to…
