Application and design character of ammonium sulfate multiple stage evaporative crystallization processes
LI Qiong;Yunnan Copper Co.,Ltd.,Southwest Copper Company;
The principle,process,equipment configuration and the design characters of the multiple stage evaporative crystallization technology applied in ammonium sulfate solution evaporation system are introduced. The process improves the processing capacity of ammonium sulfate solution and reduces steam consumption.The amount of steam consumption per ton of solid ammonium sulfate is reduced from 5 tons to 1. 5 tons.This greatly relieves the stress caused by the insufficient steam supply during production and the energy-saving effect is prominent.
