在已确定化学生产工艺和流程后，由定性阶段转向定量阶段，通过对整个生产系统、生产车间，以及部分重要的生产单元进行物料衡算计算出主、副产品的产量，原材料的消耗定额、“三废”排放量及组成，以及产品收率等各项经济技术指标，从而定量地评述初步设计所选择的工艺路线、生产方法及工艺流程在经济上是否合理。 物料衡算的意义在化学工程中，设计或改造工艺流程和设备，了解和控制生产操作过程，核算生产过程的经济效益，确定原材料消耗定额，确定生产过程的损耗量，对现有的工艺过程进行分析，选择最有效的工艺路线，对设备进行最佳设计以及确定最佳操作条件等都要进行物料衡算。而且，化学工程的开发与放大都以物料衡算为基础的。物料衡算是质量守恒定律的一种表现形式。凡引入某一设备的物料成分、质量或体积比等于操作后所得产物的成分、质量或体积加上物料损失。 物料衡算遵循的原则1) 对一般的体系而言，物料分布均可表示为：(物料的累积率)=(物料进入率)-(物料流出率)+(反应生成率)-(反应消耗率)2) 当系统没有化学反应时，则可简化为：(物料的累积率)=(物料进入率)-(物料流出率)3) 在稳定状态下有：(物料进入率)=(物料流出率)4) 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

异丁烯选择性氧化工段、甲基丙烯酸甲酯合成工段、甲基丙烯酸甲酯精制工段。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）确定甲基丙烯酸甲酯的实际产量以及质量指标； （2）确定氯仿、甲醇、对苯二酚、氧气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；（5）汇总全流程物料衡算，数据用于完成物料流程图等后续设计任务4.2高纯异丁烯氧化工段物料衡算 图4.1高纯异丁烯氧化工段流程图由工艺流程图可知，高纯异丁烯氧化工段有反应器、混合罐和吸收塔等重要单元过程，需要对它们进行物料衡算。表4-1
