摘要
基于Aspen Plus流程模拟软件,运用Gibbs自由能最小化方法建立了Shell粉煤气化模拟计算模型,对新疆准东一采区的煤种进行气化过程模拟优化.以(CO+H2)摩尔分数最高为目标函数,通过单因素研究确立的最佳操作条件为:气化压力2MPa,氧煤比0.73kg/kg和蒸汽煤比0.09kg/kg;而通过虚拟正交实验研究,获得的最佳操作条件为:气化压力2MPa,氧煤比0.78kg/kg和蒸汽煤比0.05kg/kg.各因素对气化过程影响大小顺序为:氧煤比和水煤比的交互作用>氧煤比>水煤比>气化压力.
ABSTRACT With Aspen Plus software, the model of coal gasifying process for Shell fur- nace was established, and used for simulation and optimization of coal gasifying process in Xin- jiang Zhundong. With the aim of high content of （CO＋ H2 ）, by single-factor research, the optimum operation conditions are 2 MPa of pressure, 0.73 kg/kg of O2/coal and 0.09 kg/kg of H20/coal; by multi-factor research, the optimum operation conditions are 2 MPa of pressure, 0.78 kg/kg of O2/coal and 0.05 kg/kg of H2O/coal. The sequence of influence of factors is the interaction of 02/coal and H2O/coal〉O2/eoal〉 H2O/coal〉pressure.
