中海壳牌石油化工有限公司年产二十三万吨醋酸乙烯项目 物料衡算一览表 中海壳牌石油化工有限公司年产二十万吨醋酸乙烯项目物料衡算一览表2019“东华科技-恒逸石化杯”第十三届全国大学生化工设计竞赛中海壳牌石油化工有限公司年产二十三万吨醋酸乙烯项目物料衡算一览表团队名称： We Win团队 团队成员： 秦丹倪 刘 娜 王甜甜 苏振宁 杨学琳指导老师： 孙晓岩 夏 力 陶少辉 王 政 秦洪庆 2019年8月1.1概述本项目以总厂在广东省惠州市大亚湾石化区的120万吨/年裂解制乙烯装置为依托，园区内公司提供氧气，进口乙烯为原料。总厂的乙烯由管道进入，经换热后，与醋酸和氧气在醋酸蒸发器混合，进入反应器反应，出口气体经气体分离塔，气液分离器等分离设备后，将混合液体与不凝气体分离，分别进入吸收工段和精制工段。来自反应工段的不凝气体，包含有大量未反应的乙烯，和产生的二氧化碳，经过水洗塔，用吸收剂经过吸收塔和解吸塔后，将大部分乙烯循环，部分不凝气放至火炬系统，得到高纯度二氧化碳。来自反应工段的混合液体，混合有水、醋酸和大量的醋酸乙烯以及乙醛，经过一系列精馏塔后，使醋酸循环使用，并且得到高纯度的醋酸乙烯产品和乙醛副产品。设计过程中利用Aspen Plus对全流程进行模拟，并在此基础上完成物料衡算、能量衡算。1.2物料衡算目的工艺设计中，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，并可作为检查原料利用率及三废处理完善程度的一种手段。1.3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：dFdt=FIN-FOUT+GR-CR当系统无化学反应发生时，有：dFdt=FIN-FOUT 在稳定状态下，有：dFdt=FIN-FOUT=0，FIN=FOUT式中：FIN进入系统的物料流率；FOUT流出系统的物料流率；GR反应产生物料速率；CR反应消耗物料速率。1.4物料衡算任务通过对系统整体以及部分主要单元的详细物料衡算，得到主、副产品的产量，原料的消耗量，“三废”的排放量以及最后产品的质量指标等关键经济技术指标，对所选工艺路线、设计流程进行定量评述，为后阶段的设计提供依据。1.4.1反应工段l
