烯酯合成工段继续反应，分离出醋酸和乙烯的反应产物继续通过精馏将醋酸乙 烯酯产品分离出来，得到优等品醋酸乙烯酯。 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，技术上是否先进，为后阶段的设计提供数据。 扬子石化年产 10 万吨醋酸乙烯酯项目物料衡算书 2 / 46 物料衡算原理 系统累计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： = = 0，= 注： 进入系统的物料流率； 流出系统的物料流率； 反应产生物料速率； 反应消耗物料速率。 扬子石化年产 10 万吨醋酸乙烯酯项目物料衡算书 3 / 46 第二章 物料衡算任务 对于本厂，工艺年开工以甲基丙烯酸甲酯合成装置 325 天/年（8000 小时） 为准的连续操作，其中一年内的五六周（约 40 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： 确定产品醋酸乙烯酯的产量以及质量指标； 确定吸收液、循环量以及损失率等指标； 确定工艺中的“三废”排放量等公共经济指标； 各主要单元过程的物料衡算，并指导工艺设备的尺寸确定； 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。 扬子石化年产 10 万吨醋酸乙烯酯项目物料衡算书 4 / 46 第三章 物料衡算 3.1 醋酸乙烯酯合成工段 图图 4-1 醋酸乙烯酯合成工段工艺流程简图醋酸乙烯酯合成工段工艺流程简图 扬子石化年产 10 万吨醋酸乙烯酯项目物料衡算书 5 /
