| Abstract: | The separation process was introduced for separating qualified ethyl acetate from waste ester solution.Acidic components were precipitated from waste ester solution according to the differential solubility of components in water solution.Based on the distillation theory,suitable thermodynamic equations were chosen.The separation process was simulated by simulation software.The optimal operation conditions and equipment parameters were determined by the comparison of total cost for distillation.The results indicated that the two-tower process was suitable for separating the qualified ethyl acetate from the waste ester solution and annual economic benefit was more than 5.001 million yuan. |
