| Abstract: | In the light of the characteristics of small nitrogenous fertilizer plants of 40~60 kt/a in capacity,it is proposed that the high isobaric methanation-methanolation technology be adopted for the revamp of the purification process for raw syngas.In line with the revamp experience of Zhejiang Shaoxing Chemical Co.,Ltd.,the advantages of the process are described,viz.,simple process flow,convenient operation,high space-time yield of the catalysts,high single-pass CO conversion, low CO CO2 content in exit gas phase,large range of regulation of methanol-ammonia ratio,and stable production. |
