Liquid chlorine at 22°C is pumped continuously to the chlorine vaporizer. The vaporization process causes the temperature of the chlorine to drop. Take the heat of vaporization of chlorine to be 290 kJ/kg and the heat capacity of chlorine vapor to be 0.48 kJ/(kg∙°C).

(a) The heat required to keep the exiting chlorine temperature at 5 C is supplied by saturated steam at 2 bar (absolute) condensing in a coil submerged in the liquid chlorine in the tank. The condensate emerges at the saturation temperature of the steam. Calculate the required rate of steam condensation.

(b) If the vaporization process were adiabatic, what would be the temperature of the exiting chlorine vapor? (Suggestion: Take a basis of 1 kg of chlorine liquid at 22°C, calculate the enthalpy gain when chlorine vaporizes at that temperature, and equate it to the enthalpy loss when the vapor cools from 22°C to the adiabatic vaporization temperature.) Is the result physically possible?
