| 摘 要： | 以石油焦为气化原料,基于Aspen plus模拟软件建立了石油焦-空气水蒸气气化制备氨气合成气模型,在验证模型的基础上,进行了气化过程的模拟仿真计算,分析了不同条件下(气化温度、气化压强、ER、S/PC)对气化气体体积分数、合成气(H_2+N_2)产率、φ(H_2)/φ(N_2)的影响.结果表明:升高温度或者增大压强都会使氢气的体积分数降低,低温低压适合制取氨气合成气;增大ER会使φ(H_2)/φ(N_2)比值下降,同时合成气的产率会提高;增大S/PC会使φ(H_2)/φ(N_2)比值上升,合成气的产率也会提高.

| Abstract: | A petroleum gas-air steam gasification process for synthesis of ammonia gas was established based on Aspen plus simulation software using petroleum coke as the gasification feedstock. Based on the verification model, the simulation and calculation of the gasification process were carried out. Influence of the gasification temperature, gasification pressure, ER and S/PC on the volume fraction of the syngas, syngas yield and the molar ratio of H2 to N2were analyzed. The results showed that increasing the temperature or increasing the pressure will decrease the volume fraction of hydrogen. Low temperature and pressure are suitable for preparation of ammonia synthesis gas. Increasing ER will decrease the molar ratio of H2 to N2 and increase the yield of synthesis gas. S/PC will increase the molar ratio of H2 to N2 , and the syngas yield will also increase. |
