| Popis: | The entire process of Coal-to-SNG plant had been modeled utilizing Illinois #6 coal as a feedstock. Shell's coal gasification process and Topsoe's recycle energy-efficient methanation process were utilized in process modeling of gasification and methanation processes. The simulation results of this Coal-to-SNG process model using Illinois #6 coal as a feedstock were well-matched with the experimental data, indicating that this entire model was feasible to do further research using IBC coal as a feedstock. Two drying methods were utilized for drying the IBC coal because of its higher moisture content. When only changing the feedstock from Illinois #6 coal to IBC coal in this Coal-to-SNG process model, the CH4 purity and yield were 83.5 mol% and 0.264 kg/kg-coal (dry basis); however, the CH4 purity and yield reached 94.4 mol% and 0.306 kg/kg-coal (dry basis) when syngas recycle drying concept was also applied in feedstock process model. The sensitivity and energy analyses were adopted for evaluating performance of this entire process. The total input energy was saved about 30% by utilizing syngas recycle drying concept. When taking coal prices into consideration, the Low Rank Coal-to-SNG process using IBC coal as a feedstock with syngas recycle drying concept becomes more feasible and attractive. © 2016 Curtin University of Technology and John Wiley & Sons, Ltd. |
