Mass Transfer As the reflux ratio in a distillation coloumn is increased from the minimum, the Liquid flow increases while the vapor flow decreases for a system Slope of the operating line in stripping section decreases Total cost first decreases and then increases Number of plates decreases very slowly first and then more and more rapidly Liquid flow increases while the vapor flow decreases for a system Slope of the operating line in stripping section decreases Total cost first decreases and then increases Number of plates decreases very slowly first and then more and more rapidly ANSWER DOWNLOAD EXAMIANS APP
Mass Transfer In case of steam distillation, the steam leaving the liquid is not completely saturated with distillate vapour, because Total pressure is less Mixing of steam with the material being vaporised is not so intimate as to result in equilibrium condition Temperature is less Saturated steam is used for steam distillation Total pressure is less Mixing of steam with the material being vaporised is not so intimate as to result in equilibrium condition Temperature is less Saturated steam is used for steam distillation ANSWER DOWNLOAD EXAMIANS APP
Mass Transfer In distillation column design, the McCabe-Thiele procedure is inadequate and a Ponchan-Savarit procedure is needed, when Saturated feed is not used The latent heat of vaporisation of the more and less volatile components are greatly different A total condenser is used An azeotrope forms Saturated feed is not used The latent heat of vaporisation of the more and less volatile components are greatly different A total condenser is used An azeotrope forms ANSWER DOWNLOAD EXAMIANS APP
