Mass Transfer In an operating distillation column, the Highest temperature is encountered at the top of the column Driving force for the liquid flow is its specific weight Driving force for the vapor flow is the pressure drop, as the pressure decreases gradually from the bottom to the top of the column Vapors and liquids are at their dew point and bubble point respectively Highest temperature is encountered at the top of the column Driving force for the liquid flow is its specific weight Driving force for the vapor flow is the pressure drop, as the pressure decreases gradually from the bottom to the top of the column Vapors and liquids are at their dew point and bubble point respectively ANSWER DOWNLOAD EXAMIANS APP
Mass Transfer If the solubilities of different components (in a liquid-liquid extraction system) increase with rise in temperature, then the temperature above which they dissolve completely is known as the critical solution temperature (CST or consolute temperature). If solubilities increase with decrease in temperature, then CST is the temperature below which they dissolve completely. If a binary system has no critical solution temperature, it implies that The system comprises of miscible liquids On heating, a vapor phase will appear ; while on cooling, a solid phase will appear The system comprises of partially mis-cible liquids The system comprises of an azeotrope The system comprises of miscible liquids On heating, a vapor phase will appear ; while on cooling, a solid phase will appear The system comprises of partially mis-cible liquids The system comprises of an azeotrope ANSWER DOWNLOAD EXAMIANS APP
