【Abstract】 Study production process of purifying naphthenic acid by using inorganic ceramic membrane, and observe affects of operating mode, membrane pore size, temperature and pressure on the process. It is found from experiment that membrane separation is best, maximum flux of the membrane 130L/h.m2, and crude acid product value 170mg.KOH/g by using inorganic ceramic membrane and alternate filtration operating mode.更多还原
