【Abstract】 In the vacuum cooling crystallization process,the cooling capacity is an important technical parameter. For a certain composition solution,the greater the evaporation capacity, the greater the heat of water vaporization,the greater the vacuum cooling capacity,and the greater the production capacity. The main factors affecting the cooling capacity are:extraction rate, initial temperature of solution, end temperature of solution,initial temperature of steam,end temperature of steam,steam density and latent heat of evaporation. This paper studies and discusses the calculation method of cooling capacity in the process of vacuum cooling crystallization.更多还原
