摘要:
The mathematical model taking into account the effects of temperature and concentration polarization and steam depression over solution was presented. The steam conductivity coefficient for film membranes MFFK2, MFFK 3, MFFK4 was experimentally determined and analyzed. The equations for temperature calculation of hot and cold membrane surfaces were obtained which are necessary to consider for calculation the temperature polarization effect. The modified equation for steam conductivity in which the effect of depression of steam over a solution and concentration polarization is considered was offered. The parameter reflecting given effect was experimentally determined for sea water membrane distillation. The engineering calculation technique of membrane distillation was developed.
