Innovative methanol synthesis process by using exergy recuperative pressure and heat circulation modules

The demand for methanol will continue increasing methanol is attractive as fuel applications and chemicals. To reduce energy requirements for the methanol synthesis, it is necessary to investigate a whole process and to retrofit it with energy saving processes. Recently, the authors developed a self-heat recuperation technology (SHR) for saving energy and developed the exergy recuperative pressure and heat circulation modules to expand SHR to the pressure recovery. In this paper, the feasibility of applying exergy recuperative pressure and heat circulation modules to the methanol synthesis process was investigated and an innovative process for methanol synthesis process was developed from the energy saving point of view. By installing exergy recuperative pressure and heat circulation modules to the methanol synthesis process, the energy consumption of the process can be greatly reduced.
