Analysis of material and energy balances in convontional reforming process shows that two sections in the process consume large amount of energy: heat transfer through rediation and combustion of flue gas in the primary reformer, compression of the process air and combustion in the mixer in the secondary reformer. This article puts forward a new energy conservation method after briefly reviewing on improved energy-saving proposals published abroad. It is expected that by using that method the total energy consumption in a largesize ammonia plant with natural gas as feedstock can be reduced to 26 GJ/t NH_3, saving about 4 GJ/t NH_3 in comparison with a well designed conventional reforming process. And the investment for both is almost the same.

对常规转化工艺的物料和能量平衡的分析结果表明,转化系统中耗能大的两个环节为:第一段转化器中的辐射传热和烟气燃烧过程;工艺空气的压缩和在第二段转化器中的混合燃烧过程。简评国外已发表的改进方案,并推荐一节能新方案。采用此新方案,可使大型天然气氨厂的总能耗降至26GJ/tNH_3,比常规转化工艺的较好设计省能约4GJ/tNH_3,而投资同常规方法大致相当。
