Mass Transfer In an operating distillation column, the Driving force for the vapor flow is the pressure drop, as the pressure decreases gradually from the bottom to the top of the column Highest temperature is encountered at the top of the column Driving force for the liquid flow is its specific weight Vapors and liquids are at their dew point and bubble point respectively Driving force for the vapor flow is the pressure drop, as the pressure decreases gradually from the bottom to the top of the column Highest temperature is encountered at the top of the column Driving force for the liquid flow is its specific weight Vapors and liquids are at their dew point and bubble point respectively ANSWER DOWNLOAD EXAMIANS APP
Mass Transfer On moving the feed line (q-line) from saturated liquid feed (vertical position) to saturated vapor feed (horizontal feed), if the slope of both the operating lines are to be increased, then it will result in Increased reflux ratio Greater degree of separation with a fixed number of trays None of these Increased reboiler load Increased reflux ratio Greater degree of separation with a fixed number of trays None of these Increased reboiler load ANSWER DOWNLOAD EXAMIANS APP
