从四环素尿素复盐结晶母液中回收尿素并循环利用

2016-03-27 23:03:50 杭州沃腾膜工程有限公司 已读
本发明涉及一种从四环素尿素复盐结晶母液中回收尿素并循环利用的方法,一种从四环素尿素复盐结晶母液中回收尿素并循环利用的方法,其特征是:将四环素尿素复盐结晶母液自然沉降,然后将其上清液用袋式过滤器过滤,过滤液加酸酸化,再用有机卷式膜过滤,所得透析液在55~65℃条件下减压浓缩1.5~2.5倍后得到回收尿素浓缩液,按照回收尿素浓缩液与纯尿素3~4:1的比例回用到四环素复盐结晶过程中。本发明减少了尿素的浪费,降低了四环素生产中尿素的使用量,降低污水的处理难度和处理成本,减少环境污染,可使盐酸四环素生产过程中尿素的消耗可由原来2Kg/Kg降低至0.5Kg/Kg。<u/>
权利要求(2)
1.一种从四环素尿素复盐结晶母液中回收尿素并循环利用的方法,其特征是:将四环素尿素复盐结晶母液自然沉降,然后将其上清液用孔径为5〜10 μ m的袋式过滤器过滤,过滤液加酸酸化至PH2.0±0.2,再用分子量为180〜300的有机卷式膜过滤,所得透析液在55〜65°C条件下减压浓缩1.5〜2.5倍后得到回收尿素浓缩液,按照回收尿素浓缩液与纯尿素3〜4:1的比例配比后在35〜45°C温度条件下溶解,加浓盐酸调pHl.0〜1.4后回用到四环素复盐结晶过程中。
2.按照权利要求1所述的从四环素尿素复盐结晶母液中回收尿素的方法,其特征在于所述四环素尿素复盐结晶母液自然沉降40〜80min。
说明
一种从四环素尿素复盐结晶母液中回收尿素并循环利用的方法
