概论镇海炼化柴油精制工段所排放的酸性废气含有大量的氢气及少量硫化氢、二氧化碳等，本项目采用MDEA（甲基二乙醇胺）溶液作为吸附硫化氢的吸附剂，回收率可达99.99%，并对所得的硫化氢进行资源化利用生产精细化工产品二甲基二硫醚（DMDS）和二甲基亚砜（DMSO）。废气中的CO2经分离提纯后制备甲醇，在减少碳排放的同时也可以满足后续工艺的原料所需。达到年处理8.5亿标立方米含硫酸性废气产2.6万吨二甲基二硫1万吨二甲基亚砜的目的，以实现在保护环境的同时有效利用资源以及与厂区园区产品体系的有效融合。2 物料衡算方式物料衡算是根据质量守恒定律，利用某进出化工过程中某些已知物流的流量和组成，通过建立有关物料的平衡式和约束式，求出其他未知物流的流量和组成的过程。系统中物料衡算一般表达式为：系统中的积累=输入-输出+生成-消耗式中生成或消耗项是由于化学反应而生成或消耗的量；积累量可以是正值，也可以是负值，当系统中积累量不为零时称为非稳定状态过程；积累量为零时，称为稳定状态过程。稳定状态过程时，可以简化为：输入=输出-生成+消耗对无化学反应的稳定过程，又可表示为：输入=输出物料衡算包括总质量衡算、组分衡算和元素衡算。各种衡算方法的适用情况如下表所示：表

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。4 总项目核算4.1 硫化氢提纯工序物料衡算表
