Two process models for carbon dioxide (CO2) utilized gas-to-liquids (GTL) process mainly producing methanol were developed by Aspen Plus software. Both models are mainly comprised of a reforming unit, a methanol synthesis unit and a recycle unit. With recycling, it was found that the energy efficiency was successfully improved and the net CO2 emission was significantly reduced, compared to the conventional GTL process. Meanwhile, the energy efficiency was sensitive to the recycle ratio and more recycle seemed to be favorable for improving CO2 conversion, enhancing energy efficiency and reducing CO2 emission. |
