In the paper analysis of the factors influencing the efficiency of the rectification process is provided. The authors show that existing dependences, equivalent to HETP, cannot be used for calculating rectification plate columns and columns with vortex nozzles, in which the coefficients of mass transfer are substantially dependent on the irrigation density and the gas/steam velocity. The dependence of the efficiency of the packet vortex nozzle as a function of the hydrodynamic regimes of the vapour and liquid phases is proposed.

W pracy przedstawiono analizę czynników efektywności procesu rektyfikacji. Autorzy wykazali, że istniejące zależności oparte o WRPT nie mogą być stosowane do kolumn półkowych i z dyszami wirowymi gdzie współczynniki transportu masy są powiązane z wielością zraszania i prędkością gazu/pary. Zaproponowano zależność efektywności dla dysz wirowych jako funkcji parametrów hydrodynamicznych pary i cieczy.
