Analysis of influence of technological parameters on efficiency of vacuum-evaporating crystallization

The theoretical analysis of influence of technological parameters on process operation and efficiency of continuous vacuum-evaporating crystallization in relation to isolation of a number of substances from their water solutions is carried out. Ranges of change of parameters at which carrying out this process is possible are established. It is shown that solution temperature before its pressure reduction, concentration of solution and pressure in a crystallizer have the strongest impact on process operation. Efficiency of process also depends on temperature depressions of solutions and physical and chemical properties of the dissolved substances
