Mass Transfer Tower diameter may be decreased by Increasing the vapour flow rate Using higher reflux ratio Increasing the liquid flow rate Use of increased tray spacing Increasing the vapour flow rate Using higher reflux ratio Increasing the liquid flow rate Use of increased tray spacing ANSWER DOWNLOAD EXAMIANS APP
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 Number of plates decreases very slowly first and then more and more rapidly Total cost first decreases and then increases Slope of the operating line in stripping section decreases Liquid flow increases while the vapor flow decreases for a system Number of plates decreases very slowly first and then more and more rapidly Total cost first decreases and then increases Slope of the operating line in stripping section decreases ANSWER DOWNLOAD EXAMIANS APP
