Mass Transfer Steam distillation is not recommended to be used, if the Azeotropic mixture is to be separated and the final product is miscible with water Material can not be distilled by indirect heating even under low pressure, because of the high boiling temperature Liquids decompose, if distilled directly at atmospheric pressure Material to be distilled is thermally unstable or has the tendency to react with other components associated with it, at the boiling temperature Azeotropic mixture is to be separated and the final product is miscible with water Material can not be distilled by indirect heating even under low pressure, because of the high boiling temperature Liquids decompose, if distilled directly at atmospheric pressure Material to be distilled is thermally unstable or has the tendency to react with other components associated with it, at the boiling temperature ANSWER DOWNLOAD EXAMIANS APP
Mass Transfer As the reflux ratio in a distillation coloumn is increased from the minimum, the Total cost first decreases and then increases Liquid flow increases while the vapor flow decreases for a system Slope of the operating line in stripping section decreases Number of plates decreases very slowly first and then more and more rapidly Total cost first decreases and then increases Liquid flow increases while the vapor flow decreases for a system Slope of the operating line in stripping section decreases Number of plates decreases very slowly first and then more and more rapidly ANSWER DOWNLOAD EXAMIANS APP
