Alkaline-free sweetening with activator ( AFSA) has been developed as a new process of purification free from the shortcomings of the Merox process. 无碱液活化剂脱臭(ASFA)的精制过程完全克服了Mcrox过程的缺陷。
In the process no waste liquid is drained. The sweetening efficiency is much higher than the Merox process. Besides, the catalyst is noted for its long life and high activity. 实验室研究和工业试验结果表明,该过程无废液排放,与应用最广的Merox过程相比,脱臭效率高,催化剂寿命长、活性高。
