On refining by distillation or crystallization in processes with flow of refined substance
National Science Center "Kharkov Institute of Physics and Technology", Academic st., 1, Kharkov, 61108 Ukraine
By analogy with distillation refining of a flowing liquid, the possibility of refining by pulling a crystal from a melt stream is considered. The technological parameters of the named processes are (in addition to the effective separation coefficient) the evaporation rate or crystallization rate, respectively, and the evaporation surface area or crystal cross-section, respectively, and the flow of refined substance. The fundamental possibility of implementing continuous crystallization refining using a thin layer of melt to increase the purification efficiency is noted.
