摘要: The invention is directed to a process for separating a compound from an aqueous feed stream wherein said compound is dissolved.
The process of the invention comprises
- adding a crystallisation agent to said feed stream, thereby causing at least part of said first compound to crystallise, resulting in a mixture of crystals and a liquid,
- separating at least part of the crystals from the liquid, leaving a supernatant,
- subjecting at least part of the supernatant to a membrane separation process, producing a concentrate;
wherein the crystallisation agent comprises a second compound with a higher solubility in water than the first compound.摘要翻译: 本发明涉及从溶解有所述化合物的含水进料流中分离化合物的方法。 本发明的方法包括: - 向所述进料流中加入结晶剂,由此使所述第一化合物的至少一部分结晶,产生晶体和液体的混合物; - 从液体中分离出至少部分晶体, 留下上清液, - 将至少部分上清液进行膜分离过程,产生浓缩物; 其中所述结晶剂包含与所述第一化合物相比在水中的溶解度更高的第二化合物。
