Plus对全流程进行模拟，并在此基础上完成物料衡算、能量衡算，Aspen Plus模拟流程如图1所示。本流程主要分为四个工段，分别是VAM合成工段、乙炔气分离工段、副产物乙醛精制工段、VAM及醋酸精制工段。本场所需主要设备有反应器、气液分离器、精馏塔、泵、压缩机、换热器、蒸发器、搅拌釜等，涉及到的原料有乙炔、醋酸等等，输入整个系统的能量主要有电能、加热介质带入的能量等，输出的能量主要有冷却剂带走的能量和输出物料的焓。2.物料衡算的目的与原理工艺设计中，物料衡算是在工艺流程确定后进行的。目的是根据原料与产品之间的定量转化关系，计算原料的消耗量，各种中间产品、产品和副产品的产量，生产过程中各阶段的消耗量以及组成，进而为热量衡算、其他工艺计算及设备计算打基础。系统的物料衡算以质量守恒为理论基础，研究某一系统内进出物料量及组成的变化，即： 系统累积的质量=输入系统的质量-输出系统的质量+反应生成的质量-反应消耗的质量假设系统无泄漏，有当系统无化学反应发生时，有在稳定状态下，有3.各工段物料衡算3.1VAM合成工段表1
