On the temperature difference in the vaporization of liquid chlorine

When calculating the heat exchange area required for the vaporization of liquid chlorine, it is necessary to determine the average temperature difference. I don’t know what values to use for the initial temperatures of liquid chlorine and hot water, as well as their temperatures after heat exchange Thank you all.

It is related to pressure; this can be found in chlor-alkali chemical industry manuals.
The temperature of liquid chlorine refers to the temperature of the liquid chlorine in your storage tanks. The temperature after vaporization is related to the pressure required by the units that use chlorine downstream. The temperature of the hot water entering the vaporizer should be about 20 degrees higher than the liquefaction temperature of chlorine corresponding to the pressure of the chlorine gas after vaporization. The exit temperature of the hot water should be reduced by 5-10 degrees. It’s not a bad idea to have a larger heat exchange area; definitely don’t make it too small, as this will prevent an adequate amount of vaporization and thus affect the normal operation of the processes downstream.
I really want to learn * Thank you~! ! !
