摘要

间歇过程流股对时间的依赖性增加了其换热网络综合的难度。提出了一种采用间接换热进行换热网络综合的方法，且考虑了直接换热，同时提出了合并热储罐的方法，并利用热储罐的特点合并间接换热中的换热器，用以减少设备费用，以热储罐中介质的温度为变量以年度总费用最小为目标函数建立非线性规划数学模型，确定热储罐内介质温度，最后将该方法应用于实例中证明此方法的有效性。

Abstract

Having time-dependent streams makes the heat exchanger network (HEN) synthesis of batch process much more complicated than its continuous partner.In this paper

heat storages are employed to overcome the time-dependent limit and heat storages and heat exchangers are combined for sake of equipment cost reduction.To obtain the optimal solution

a nonlinear programming (NLP) with the objective of minimize total annual cost is established for the overall HEN synthesis

including the optimization of heat storage temperatures.At last an example is used to show the application and effectiveness of the proposed methods.
