摘要:
利用Aspen Plus模拟软件,分析进料热状况对精馏能耗的影响.结果表明,当进料流量和组成、产品流量、塔板数和板效率、回流比等参数不变的情况下,随着进料热状况的改变,塔的分离能力和塔内气体和液体流量也随之改变.冷液进料时,塔的分离能力较高,但是能耗较大.随着进料热状况参数q的数值减小,塔的分离能力下降,但是能耗也随着减小.在能够满足分离要求的前提下,使进料处在较小q值的热状况,可以达到节能目的.
Abstract:
In this article effect of thermal conditions of feed on energy consumption of distillation is studied by simulation of Aspen Plus software and theoretical analysis.Results show that when feed rate and composition,products flow rate,number of plates,plate efficiency,reflux ratio are constant,separating power of column,flow rate of vapor and liquid in column change as change of feed condition.At cold feed separating power of column is stronger,but energy consumption is bigger.As reduction of parameter of thermal condition of feed q separating power of column is cut down,but energy consumption is also cut down.On condition requirement of separation can be met,column should be operated at less q to reduce energy consumption of distillation.
