摘要
以粗苯为溶剂萃取脱酚，粗苯的主要消耗是其在处理后氨水中溶解的损失。适当降低萃取操作温度，可以明显降低粗苯消耗，而不会影响其脱酚效率。
The major problem of solvent extraction dephenolization process is that crude benzol dissolve in ammonia liquor.The consumption of crude benzol is obviously reduced by decreasing the extraction temperature properly and it doesn’t influence the efficiency of dephenolization.
