Abstract
It was preliminary designed that 200000t/a industrial sulfuric acid production line which using pyrite mine as raw material. This dissertation introduced the property and use of sulfuric acid. After the considerations to the degree of process maturation and technology condition home and abroad, the reasonable process was defined.
According to the process of technological design, the material – balance calculation were introduced for main unit. The heat – balances were also calculated in the conversion section, and the heat exchange quantity was calculated in each heat exchanger. According to the material balance, the thermal balance and the design require, the ordinance of the drying tower were determined.
