| Abstract: | Connected transformed. Through tions on the pipeline with the production craft of potassium sorbate, the recycling craft of sorbic acid was the tar pretreated, the raw materials adjusted and the pipeline disposed, the quesfrequently stopped up, the unit operation time too long and the low recovery effect of sorbic acid were thoroughly settled. The yield of the sorbic acid is improved from 63.9% to 98.1% ;the unit operation time is shortened from 4 h to 2 h. The sorbic acid of recovery and the materials saved brings an annual income of 2 938 700 RMB Yuan;the discharge of waste solution reduced 12 658 m^3/a. |
