摘要
利用先进化工模拟软件对乙二醇有机废料精馏回收过程进行模拟和优化,对塔板数、回流比、进料位置及塔顶采出量等操作参数进行灵敏度分析。模拟计算得到乙二醇有机废料精馏塔的设计参数为:理论塔板数30,回流比3,进料位置第11块塔板,塔顶采出量470 kg/h。以设计参数为基础,应用BHS型高效填料进行设计计算。通过经济效益分析,每年可从有机废料中回收乙二醇3 384 t,带来经济效益共为2 368.8万元。
The advanced simulation software is used to simulate and optimize the distillation recycling process of ethylene glycol organic waste. The effects of plate number, reflux ratio, feed-stage and the overhead recovery on the sensitivity are studied. The optimal operation parameters of distillation column for recycling ethylene glycol organic waste are as follows：30 of theoretical plates,3 of reflux ratio, 11 of feed-stage and 470 kg/h of overhead recovery. The BHS- efficiency packing design calculation is also conducted. Through the economic analysis, about 3384 t/year of organic waste can be recycled, which will bring economic benefit about 23. 688 million yuan every year in total.
