摘要
利用Aspen Plus流程模拟软件模拟了300万t规模合成油项目驰放气制备LNG(液化天然气)及LNG-合成氨联产流程,在此基础上分析了两种方案的技术经济指标.结果表明,LNG单产项目温室气体CO2的排放量比LNG-合成氨联产项目少4.94万t/a,能源利用效率比联产项目高22.2%,利润少164万元/a~165万元/a.综合比较了CO2排放量、能效及利润,得出LNG单产项目技术经济指标优于LNG-合成氨联产项目.
Based on the 3 million tons-scale project of Fischer-Tropsch Chi-deflated gas data, the processes of Chi-deflated gas to LNG (liquefied natural gas) and LNG-ammonia-generation projects were simulated using the Aspen plus simulation software respectively; meanwhile, the technical and economic index of the two programs were analyzed. The simulation results showed that the emission of greenhouse gases CO2 of the LNG project is less 49,400 t/a than that of the LNG-ammonia-generation projects, the energy efficiency higher 22.2 % than that of the latter one, while the profit is less 1.64-1.65 million RMB/a. According to a comprehensive consideration of CO2 emissions, energy efficiency, and profit, we believe that the project of LNG is better than co-generation.
