6、程1.0适用范围本标准叙述了以硫铁矿为原料，采用接触法制硫酸的生产装置、生产原理、工艺过程、生产操作和主要工艺指标等。本标准适用于本公司200kt/a硫铁矿制酸及炉气余热发电生产装置。2.0产品简介2.1产品特性2.1.1硫酸的物理性质2.1.1.1硫酸是三氧化硫（SO3）和水（H20）的化合物，一个三氧化硫分子和一个水分子结合得到的就是纯硫酸（H2SO4），纯硫酸的分子量为98.08，是无色、无臭、透明的油状液体。2.1.1.2硫酸的密度硫酸的密度随浓度和温度的不同而发生变化，同一浓度的硫酸，它的

7、密度随温度的升高而降低。因此，同一浓度的硫酸在不同温度下其密度也不同。在20℃时，93%硫酸的密度为1.82g/cm3，98%硫酸的密度为1.84g/cm3。2.1.1.3结晶温度硫酸水溶液的结晶温度随着硫酸含量的不同而在一个极广泛的范围内变化。硫酸的结晶温度表（见下表）硫酸浓度%结晶温度℃硫酸浓度%结晶温度℃75-29.592-17.576-22.292.5-22.015277-15.593-27.078-9.593.5-31.279-5.094-31.980-0.194.5-26.5813.39
