What additional equipment is needed to feed liquefied chlorine gas from a ton cylinder?

To effectively feed liquefied chlorine gas from a ton cylinder, an evaporator is essential. Chlorine is stored in a liquid form under pressure in ton cylinders, and when it needs to be dispensed for use in water treatment processes, it must be converted from its liquid state to a gaseous state.

The evaporator facilitates this conversion by carefully controlling the temperature and pressure conditions, allowing the liquid chlorine to vaporize and flow into the system where it can then be dosed appropriately.

This process is crucial because directly using liquid chlorine without evaporation could lead to improper dosing and potential hazards, as the properties and handling of gaseous chlorine differ significantly from those of its liquid form.

Other equipment, like a pump, might be considered in various applications; however, chlorine gas feeding primarily requires an effective means of vaporization, which the evaporator provides. Thus, the evaporator is the key piece of equipment that fulfills the requirement for safely and efficiently feeding chlorine gas from its liquid storage state.
