【摘要】 针对乙酸乙烯精馏工艺能耗高的问题,利用流程模拟软件对该过程进行了模拟计算得到了最优操作参数。同时根据热力学第一定律,提出了两条能量利用的方案充分回收利用了精馏过程本身能量。提高了能量利用效率,达到了节能的目的,工业应用取得了良好的经济效益。更多还原

【Abstract】 Aiming at the problems of high energy consumption,we use the Aspen Plus flowsheeting simulation software to optimize the vinyl acetate distillation process and get the optimal parameters.According to the the first law of thermodynamics,we put forward two measures of energy saving to recovery the distillation process energy and improve energy efficiency to achieve the purpose of energy saving,.The economic benefits of industrial applications were considerable.更多还原
