最近,中石化南京化学工业有限公司氮肥厂收到了上海化工研究院专门送来的荣誉证书,他们共同开发的“含二氧化碳的稀氨水解吸塔”项目获上海市发明创造专利一等奖。这次上海市共表彰了五个一等奖,该项目占了一席之地。该厂合成氨铜洗和双提水洗副产的稀氨水浓度为1.5%～2%,流量约12～15吨/小时,从1984年开始,该厂将这部分稀氨水经解吸塔提浓、碳化后制成碳化母液供兄
Recently, the SINOPEC Nanjing Chemical Industry Co., Ltd. Nitrogen Fertilizer Plant received a certificate of honor from the Shanghai Chemical Industry Research Institute. The co-developed “Carbon Dioxide Ammonia Leaching Desorption Tower” won the first prize of Shanghai Invention and Creation Patent. This time, Shanghai City awarded a total of five first prizes, the project took a place. The factory ammonia ammonia copper washing and double-washing by-product of dilute ammonia concentration of 1.5% to 2%, the flow of about 12 to 15 tons / hour, from 1984 onwards, the plant will dilute the ammonia through the desorption column concentration, carbonation After the carbon mother liquor for brother
