总论本项目依靠苏里格第二天然气处理厂为总厂，以经过天然气厂处理过后的天然气作为原料，建造一个年产量60万吨的醋酸乙烯厂。本厂采用天然气部分氧化路线制取乙炔，再通过副反应产生的合成气通过费托合成以及甲醇羰基化反应制备得到醋酸，将醋酸和乙炔直接进行加成反应即可得到醋酸乙烯产品。同时为了提供天然气部分氧化所需的氧气，本厂单独建立空气分离工段，副产普通氮气和高纯度氩气，同时空分提供的冷量可以用于后续工段的深冷分离，来达到节省能量的作用。整体工艺流程达到了极高的原子利用率，实现了整体绿色高效的生产过程。物料衡算是在确定生产工艺及流程后，对于每个生产单元、全部生产车间以及整个生产系统由定性分析转变成定量计算的过程，通过核算得出生产所需原料种类及数消耗量，主、副产品种类及产量，“三废”组成及排放量等相关物流数据。以推算的产品收率等各项经济技术指标，定量地评价初步设计所选的工艺路线、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。第二章 物料衡算原理物料衡算主要依据在化学反应和化工单元操作中满足质量守恒定律，进而推导得出如下平衡关系式：系统累计质量=输入系统质量输出系统质量反应生成质量反应消耗质量假设系统无泄漏、挥发等现象，有：当系统无化学反应发生时，有：在稳定状态下，有：注： 进入系统的物料流率； 流出系统的物料流率； 反应产生物料流率； 反应消耗物料流率。第三章 物料衡算任务在本次物料衡算中，以全年开工合成醋酸乙烯装置333天/年（8100小时）为准的连续生产操作，剩余32天时间用于生产过程中正常检修工作以及突发安全事故或产品纯度问题下紧急停车处理。物料衡算主要任务如下所示：确定主产物醋酸乙烯、副产物氩气、氮气的实际产量以及质量指标；确定空气原料、天然气原料、醋酸原料的年消耗量以及原材料规格；确定吸收剂乙醇胺的循环量以及损失率等指标；确定生产全流程中“三废”排放量以及公用工程等公共经济指标；计算各操作单元的出、入流股组成和流量，为设备选型提供负荷要求；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。（注：本表格由Aspen直接导出，数据精度与Aspen模拟计算相同）第四章
