VAC精制工段181.5总结30能量衡算1.1总述本项目拟建一套年产20万吨醋酸乙烯酯并附带生产8万吨/年40%乙醛水溶液以及众多副产品的装置，在全工艺段中伴随着物料从一个体系或单元进入另一个体系或单元，在发生质量传递的同时也伴随着热量的消耗、释放和转化。其中的热量变换数量关系可以由热量衡算求得，对于新设计的车间，可以由此确定设备的热负荷。再根据设备的热负荷大小、所处理物料的性质及工艺要求选择恰当的设备。总而言之，通过下述热量衡算，可以为后续设计工作中提高热量的利用率，降低能耗提供主要依据。1.2 热量衡算原理工程依据化工设计中关于热量衡算的基本思想和要求，遵循基本规范与实际工艺相结合的原则，进行热量衡算书的编制。其中一个主要依据是热量平衡方程：其中，表示输入设备热量的总和；表示输出设备热量的总和；表示损失热量的总和。对于连续系统：其中，设备的热负荷；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。在进行全厂热量衡算时，是以单元设备为基本单位，考虑由机械能转换、化学反应释放和单纯的物理变化带来的热量变化。最终对全工艺段进行系统级的热量平衡计算，进而用于指导节能降耗设计工作。1.3 热量衡算任务在进行脱硫并资源化利用装置的热量衡算中，主要通过定量计算完成下述基本任务：确定工艺单元中物料输送机械（如泵）所需要的功率，以便于进行设备的设计和选型；确定精馏等单元操作中所需要的热量或冷量以及传递速率，计算换热设备的尺寸，确定加热剂和冷却剂的消耗量，为后续设计中比如供汽、供冷、供水等专业提供设备条件；确定为保持一定反应温度所需移除或者加入的热传递速率，指导反应器的设计和选型；提高热量内部集成度，充分利用余热，提高能量利用率，降低能耗；最终计算出总需求能量和能量的费用，并由此确定工艺过程在经济上的可行性。1.4
