摘要
介绍了江西电化有限责任公司新、老两套甘氨酸生产装置的流程 ,指出新装置具有下列优点 :(1)采用了乌洛托品的溶液投料 ;(2 )采用 5℃冷冻水降低醇析温度 ;(3)采用甲醇高位槽加醇析用甲醇 ;(4 )采用液氨贮槽代替液氨钢瓶供氨 ;(5 )采用精馏塔塔釜连续排液装置 ;(6 )改变氨化釜恒温和醇析加甲醇方法。采用新装置后 ,5 0 0 0t/a甘氨酸装置可节省资金 35 4.4万元 /a。
Both the old and the new processes of aminoacetic acid production in Jiangxi Electrochemical Co.,Ltd. were introduced.The new equipment had the following advantages:hexamethylene- tetramine is supplied to reactor in the form of solution,the temperature of alcohol precipition is decreased by using 5 ℃ water as cooling medium,methanol for alcohol precipitation is from methanol high level tank,ammonia is supplied from liquid ammonium tank instead of cylinder,liquid in rectifying still is discharged continuously,the temperature of ammonation solution is kept constant in alcohol precipitation kettle instead of ammonation reactor,addition method of methanol for alcohol precipitation is changed. After adopting the new equipment,3.544 million RMB$/a can be saved in the production of 5 kt/a aminoacetic acid .
