物料衡算的目的工艺设计中，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。对于已有装置，物料衡算可以弄清原料的来龙去脉，找出生产中的薄弱环节，为改进生产、完善管理提供可靠的依据和明确方向。 第二章 物料衡算方法物料衡算是根据质量守恒定律，利用某进出化工过程中某些已知物流的流量和组成，通过建立有关物料的平衡式和约束式，求出其他未知物流的流量和组成的过程。系统中物料衡算一般表达式为： 系统中的积累=输入-输出+生成-消耗式中，生成或消耗项是由于化学反应而生成或消耗的量；积累量可以是正值， 也可以是负值，当系统中积累量不为零时称为非稳定状态过程；积累量为零时， 称为稳定状态过程。稳定状态过程时，可以简化为： 输入=输出-生成+消耗表2-1衡算方法使用情况类别物料衡算形式无化学反应有化学反应总衡算式总物料衡算式适用适用物质的量衡算式适用不适用组分衡算式组分质量衡算式适用不适用组分物质的量衡算式适用不适用元素原子衡算式元素原子质量衡算式适用适用元素原子物质的量衡算式适用适用第三章
