New Separation Options Beckon Developments in membranes and dividing wall columns promise significant benefits

摘要

SEPARATION OPERATIONS remain an indispensaoie part or many processes.Because current separation technology often involves substantial investment and high energy consumption,work on improved options is ongoing.Membranes represent one area of considerable promise.Indeed,advancemenrs in membrane separation could revolutionize the chemical industry in 6ve-to-ten years,hope researchers in the United Kingdom and United States.Meanwhile,dividing wall column(DWC)technology is pushing the boundaries of what distillation can achieve.
