摘要
Abstract
A novel process which can purify the organic solvents from their azeotropes with water is proposed. In this process, water can be drained off both from bottom and overhead of tower at the same time, and the organic solvent is concentrated in the tower and accumulated in the middle vessel at last. So the progress is time-shortened and energy-saving. The product purity is 99. 8% and the product yield is more than 99. 5%. Simulation of liquid-liquid equilibrium (LLE) and the equipment operation data agree well with the experiment.关键词
