基于流程模拟的脱矿胜利褐煤水蒸气气化研究
Study of steam gasification of demineralized Shengli lignite based on process simulation
摘要
Abstract
Aspen Plus V14 is used to establish a steady-state process model of a fixed-bed coal gasifier,and simulation research is conducted on the steam gasification process of demineralized Shengli lignite(SL)and its added sodium hydroxide sample(SL+-NaOH).The accuracy of the built model is verified based on experimental data,and it is testified that the syngas yield predicted by the model is in good agreement with the experimental values.Based on this model,the effects of steam-to-coal ratio and gasification temperature on the composition of syngas and the yield of effective gas(CO+H2)are studied.The results show that the mole fraction of effective gas in SL+gasification syngas first increases and then decreases with the increase of steam-to-coal ratio,reaching a maximum value of 75.7％at 0.74 of steam-to-coal ratio.The gasification temperature has a greater impact on the effective gas composition of the two coal samples.The production of H2 and CO2 in SL+-NaOH increases significantly,while the production of CO decreases significantly compared with that in SL+.关键词
