RETROFITTING FOR DME PROCESS BY ENERGY-FLOW FRAMEWORK DIAGRAM

摘要

The Energy-flow Framework Diagram (EFD) is a graphic tool of thermodynamic analysis applied in energy analysis and integration of systems. This paper presents the characteristic features of the EFD and proposes a series of revelatory criterions to use the EFD. Dimethyl ether (DME) is considered as a clean fuel in the 21st century. Through an application study of the novel method on a synthesis gas based 56 kt/a one-step DME production process, the paper gives a retrofitting process and attempts to prove that the novel method and the EFD is effective and useful.
