By studying the process development of the DME synthesis presented in the literature, this work first use commercial process simulators to analyze the traditional DME processes. The engineering economic analysis and optimal operating conditions of the processes are clearly evaluated. Plantwide control schemes are then developed to meet the desired production specifications. For the newly developed DME processes such as single-step process and two-step process, process simulators are used for designing preliminary process flow diagrams (PFDs). Results of the steady-state and dynamic simulations of these DME processes are then used to demonstrate those shown in the literature. Finally, the most feasible DME process flowsheet is presented to the academic and industrial societies for further studies.
