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 对无化学反应的稳定过程，又可表示为： 输入=输出 物料衡算包括总质量衡算、组分衡算和元素衡算。各种衡算方法的适用情况如表 1-1 所示：表1-1

物料衡算任务对于本厂，工艺采取年开工333天（8000小时）的连续操作，其中一年内的四五周（约30天）用于固定的停车设备检修及紧急情况处理。物料衡算的主要任务在于：（1）确定硫铵的实际产量以及质量指标； （2）确定工艺用水的循环量以及损失率等指标； （3）确定工艺中的“三废”排放量等公共经济指标（4）各主要单元过程的物料衡算，并指导工艺设备的尺寸确定。1.4.2
