摘要
以生物质费托合成制取液体燃料工艺为基础,利用Aspen Plus软件建立其流程的仿真模型,研究各单元操作参数变化对航空煤油产量的影响,并在最优工况下对系统进行能量分析。结果表明:生物质气化单元对航油产量的影响主要来自产物合成气中H_(2)与CO物质的量之比(H_(2)/CO),最优操作条件为T=750℃,P=0.1 MPa,进口水蒸气与生物质质量比(S/B)为0.5;加大FT合成温度和压力可增大航油产量和提高能量利用效率,最优费托合成温度为230℃,压力为2.5 MPa;在最优工况下,当收益[火用]仅为航煤[火用]时,系统总[火用]效率为49.67%,若将全部副产品算入收益[火用]中,总[火用]效率为59.48%。
Based on the route of biomass gasification with Fischer-Tropsch synthesis to produce liquid fuel,and using Aspen Plus software to establish the simulation model of the process,the influence of operation parameters of each unit on aviation kerosene output was studied.The energy usage ratio of the whole system under optimal conditions was analyzed.The results reveal that the impact of biomass gasification unit on jet fuel production mainly come from the material ratio of H_(2)to CO(H_(2)/CO),the optimal gasification temperature is 750℃,pressure is 0.1 MPa,mass ratio of steam to biomass(S/B)is about 0.5.The fuel production and energy efficiency is improved with increasing FT synthesis temperature and pressure,the unit’s optimal Fischer-Tropsch synthesis temperature is 230℃,pressure is 2.5 MPa.Under the optimal condition,when the revenue exergy only contains jet fuel exergy,the total exergy efficiency is49.67%.When whole by-products exergy are included,the total exergy efficiency is 59.48%.
