【摘要】：为了降低生产成本,减少CO_2排放,实现n(H_2)/n(CO)可调,将水煤浆与天然气进行联合转化。从热力学角度对共气化过程各反应的竞争能力进行了分析。利用Aspen Plus软件对该过程进行了模拟,分析了氧气进料流量、天然气进料流量对气化炉出口温度、气体摩尔组成、合成气摩尔分数、n(H_2)/n(CO)的影响。计算了多种不同进料流量下的出口参数,通过对这些数据进行筛选,得到气化室出口温度在1 340~1 360℃之间,n(H_2)/n(CO)大于1.15,合成气摩尔分数大于0.72时的天然气和氧气的进料流量。
[Abstract]:In order to reduce the cost of production, reduce the emission of CO2, realize the n (H\ +\ -\ {}\ {\})\% (CO The competitive power of each reaction in the co-gasification process was analyzed from the viewpoint of thermodynamics. The process was simulated by Aspen Plus software. The effects of oxygen flow rate and natural gas feed flow rate on the outlet temperature of gasifier, the molar composition of gas, and the molar fraction of syngas n (H2) / n (CO) were analyzed. The outlet parameters under different feed flow rates were calculated. By screening these data, the inlet flow rate of natural gas and oxygen was obtained when the outlet temperature of gasification chamber was between 1 340 鈩，
