摘　　要：四川泸天化股份有限公司1150t/d合成氨装置在2004年的改造中,对整个合成循环系统作了较大改动,由塔前分氨改为塔后分氨,为此氢氮气压缩机段间增加分子筛系统。改造后对氢氮气压缩机和氨压缩机而言,吨氨所耗轴功率相应都有所下降。In the revamping of llS0t/d ammonia plant of Lutianhua Co., Ltd. in 2004, significant changes were made to the whole circulating system. Pre-converter ammonia separation was changed into post-converter separation; therefore, molecular sieve system had to be installed in the inter-section of H2/N2 compressor. After the revamp, the bearing power per ton ammonia consumed was decreased correspondingly in terms of H2/N2 compressor and ammonia compressor.
