摘    要:为合理利用焦炉煤气,实现焦炉煤气生产合成氨、尿素项目实现安稳长满优运行,通过分析项目中焦炉煤气气量及组分(特别是硫含量及杂质),选择压缩机、转化炉等主要设备,分析合成氨、尿素负荷的匹配,施工队伍等关键问题对项目建设和生产的影响。提出了焦炉煤气气量及组分确定方法,压缩机、转化炉选型要求,合成氨、尿素负荷匹配设计以及施工单位选择原则。应充分估算焦炉气量,搞清焦炉气成分,以便确定合理生产规模和主要工艺,特别要考虑焦炉气中杂质对工艺系统的影响。应选择性能可靠稳定的往复式焦炉气压缩机、净化气压缩机、循环气压缩机和CO2压缩机,保证生产安全稳定连续运行。

关 键 词:煤化工企业  焦炉煤气  合成氨  尿素  转化炉

Abstract:In order to use coke oven gas reasonably and guarantee the coke-oven-gas-produced synthetic ammonia and urea project oper-ate safely and stably,the project construction and its influencing factors from the aspects of coke oven gas yield and composition determina-tion were investigated,especially sulfur content and impurities,choice of compressors and reformers,ammonia and urea loading match.The results showed that,coke oven gas yield and composition determined the production scale and the main process.The influence of impurity in coke oven gas on technical system also couldn't be ignored.The stable and reliable compressors for coke oven gas,purified gas,circulating gas and CO2 were the assurance of safe production.
Keywords:coal chemical industry enterprise  coke oven gas  synthetic ammonia  urea  reformer
