Syngas (H 2+CO) is the essential raw-material for synthesis of ammonia, methanol, acetic acid and other oxygenic organic compounds, and also is the fuel for gas turbine in Integrated Gasification Combined Cycle (IGCC). Among gasification techniques, jet entrained bed gasification process which use coal water slurry (CWS) as raw-material is considered to be one of the best. The investigation on CWS gasification system has a strong industrial background and wide application prospects in China. In this paper, the process analysis for CWS gasification system has been made. Based on cold model investigation in large-scale, zone model of gasifier has been proposed, which was the fundamentals of gasifier process analysis and mathematical model. The mathematical model for other unit equipments, such as quenching chamber, nozzle scrubber and carbon scrubbing tower, has also been made. On the basis of these analysis and models, steady state simulation for the system has been carried out by applying the squential modular approch. The simulation results agreed well with the values obtained from plant operation data.
