Dimethyl ether (DME) is an emerging player in the transition toward sustainable energy solutions. The Lummus Technology CDDME℠ process is highly flexible in processing types of methanol feedstock and offers a highly intensified design compared to traditional DME processes.
Our renewable DME (rDME) technology offers a highly flexible solution to decarbonizing various future end users – from reducing emissions from LPG fuels and power generation to enabling potential transportation paths for the hydrogen market. By using its market leading catalytic distillation technology, Lummus Technology offers a DME production process with fewer unit operations, higher conversion rates, and reduced utility and operating costs that opens the door against the previously restrictive costs associated with DME production.
If you seek to use renewable sources or have been restricted by prohibitive operating or capital expenditures, our CDDME process can give you a new lever in which to increase your clean fuels production while decarbonize various end uses.
