Numerical Simulation of the Methanol Synthesis Process by Using HT-L Pulverized Coal Gasification

The numerical simulation of the methanol synthesis process by using HT-L pulverized coal gasification is studied in the work. Pulverized coal gasification are simulated by Aspen Plus industrial systems flower software, and the optimum condition can be gained by calculation. The pulverized coal entrained-flow gasifier adopts the minimization method of Gibbs free energy. Under the given conditions of 1500°C and carbon conversion of 99%, when coal flow volume is 3265.87 kg/h and the ratio of air and coal is 4:1, the content of effective gas is maximal, and also the content of effective gas increased with increasing of the pressure.
