摘要

乙二醇生产流程是一个包含十几个精馏塔和固定床催化反应器的长流程。由于流程长且反应催化剂影响不易确定等因素，乙二醇生产过程的全流程模拟十分困难。基于ASPEN PLUS软件平台，集成支持向量机、优化算法、机理建模等多种方法，建立了乙二醇的全流程模型。通过采集并处理实际生产的工业数据，采用优化算法进行模型的智能校正，进一步完善了模型的性能。乙二醇全流程模型模拟结果与实际工业过程数据相符，能够满足工业建模的要求。

Abstract

Ethylene glycol process is a long process

which includes more than ten fractionating columns and fixed-bed catalytic reactor.In the long process

there are many uncertain factors

such as catalyst deactivation and so on.Therefore the simulation of the whole ethylene glycol process is very difficult.In this paper

ASPEN PLUS software was used as a platform.Support vector machine

optimization method

mechanism modeling methods are integrated to develop the model of ethylene glycol process.With actual process data

the process model was intelligently rectified.The results of model simulation agreed with actual data fairly and the whole process model can satisfy the needs of process simulation.
