附录4-能量平衡衡算表

中科炼化100kt/a VAC和45kt/a EC项目能量平衡计算书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国石化中科炼化年产10万吨醋酸乙烯酯和4.5万吨的碳酸乙烯酯项目能量平衡计算书丹东路1号团队队伍成员：崔荣凯、赵越、崔梓铭、王金林、陈子璇指导老师：封瑞江、王吉林、龙文宇、鞠佳、梁飞雪第一章 概述本项目为中科炼化有限公司年产10万吨醋酸乙烯酯和4.5万吨碳酸乙烯酯项目，利用总厂的乙烯为原料，通过醋酸乙烯酯合成、气体分离、醋酸乙烯酯精馏、碳酸乙烯酯合成，达到原料的充分利用并实现清洁生产。 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，Aspen plus全模拟流程如图1-1、图1-2、图1-3、图1-4所示。图1-1醋酸乙烯酯合成工段图1-2 气体分离工段图1-3 醋酸乙烯酯精制工段图1-4 碳酸乙烯酯合成精制工段第二章 能量衡算原理系统的能量衡算能量守恒为理论基础，研究某一系统内各类型的能量的变化，即：输入系统的能量=输出系统的能量+系统积累的能量对于连续系统，有：注： Q设备的热负荷；W输入系统的机械能； 离开设备的各物料焓之和； 进入设备的各物料焓之和。本项目的能量衡算以单元设备为对象，计算由机械能转换、化学反应释放能量和单纯的物理变化带来的热量变化。第三章 能量衡算任务（1）确定流程中机械所需的功率，为设备设计和选型提供依据。（2）确定精馏各单元操作中所需的热量或冷量及传递速率，确定加热剂和冷剂的用量，为后续换热和公用工程的设计做准备。（3）确定反应过程中的热交换量，指导反应器的设计和选型。（4）最终计算出所需的能量和费用，判定工艺过程的经济性。第四章 能量衡算表C0101INOUTStream NoS0105S0106Total Flow
