概述热量衡算是指根据能量守恒定律而进行的热量平衡的计算，对任何一个生产过程，其中输入的热量应为输出热量与损失热量之和。通过热量衡算，可知热量的利用、消耗和损失的情况，从而可推算热量的利用效率。例如利用热量衡算，可以确定蒸馏釜中加热蒸汽的消耗量以及分(冷）凝器和冷却器中冷却水的消耗量。第二章 能量衡算的原理能量衡算的基本依据是能量守恒定律。而能量守恒定律是以化工过程的能量衡算结果为基础进行的。本工艺所需的主要设备有泵、换热器、反应器、精馏塔等。输入生产系统的能量主要有电能、热公用工程带入的热量和原料的焓值，输出的能量主要有冷公用工程带走的热量和产物的焓值。根据能量守恒定律，对于连续系统有：Q+W+Q损=Hout-HinQ设备的热负荷；Q=Hout-HinW机械能，输入为正，输出为负；Q损系统损失的热量，本计算书中忽略不计，即Q损=0；Hout进料带入系统的能量之和，本计算书中即为物料焓值；Hin出料带出系统的能量之和，本计算书中即为物料焓值。利用以上关系，可以对整个工艺系统或子系统进行能量衡算误差Error：E=Q+W-(Hout-Hin)第三章 能量衡算的任务对于本厂，工艺采取年开工300天的连续操作，物料衡算的主要任务在于：确定工艺单元中物料输送机械（如泵）和其他操作机械所需要的功率，以便于进行设备的设计和选型；确定精馏等各个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。第四章
