| Popis: | The purpose of this work is to establish the theoretical foundations for calculating and designing the sublimationcondensation processes in chemical apparatuses which are intended for production of ultrafine powders of crystalline and amorphous materials with controlled fractional composition. Theoretic analysis of the primary processes of nucleation and growth kinetics of the clusters according to the degree of super-saturation and the homogeneous or heterogeneous nature of nucleation has been carried out. The engineering design procedures of desublimation processes have been offered and tested for modification of the Claus process. {"references":["","Lamminen E., Isherwood H., Effect of process parameters on ultrafine\nand fine particles emissions.Chemical Engineering Transactions,\nVol.17, 2009, pp. 729-735.","Kashchiev D., Nucleation: Basic Theory with Applications, Butterworth\nHeinemann, Oxford, UK, 2000.","Farjoun Y., Neu J.C., Exhaustion of nucleation in a closed system,\nPhys.
