The Recycling of Sodium Acetate from Waste Liquid of Dially-Alcohol-Ketone-Acetate Production

Article Preview

Abstract:

Sodium acetate has been separated and recycled in waste liquid from production by the process of precipitation, filtration, washing, concentration, crystallization, recrystallization and drying. The recycling of sodium acetate can be completely achieved by reuse hot water and liquor produced during concentrated and crystallization process respectively. Product quality of sodium acetate accords with national standard GB/T 693-1996 chemical pure grade. In the paper, the involved method of the waste water treatment has the characteristics of simple process, convenient operation, less investment and high return. Then, energy conservation and emissions reduction can be achieved when the technological process is used. Therefore, the recycling technology is suitable for industrialized production.
