A liquefied gas, such as liquefied chlorine, which is injected into a liquid stream such as an aqueous stream, in the liquid state, is prevented from causing the liquid stream to freeze by cooling the liquefied gas to a temperature below its boiling point at the pressure of the liquid stream.

Method and apparatus for chlorinating water with liquefied chlorine

Apparatus particularly suited for use in mixing ammonia gas with hard water is disclosed. The apparatus includes an ejector assembly having a throat with a flexible tubular liner which is periodically flexed inwardly to loosen any solid matter which may have formed on the inside of the liner. The liner is flexed by a three-way valve connected to the water supply line and controlled by timers and a pressure switch. If desired, a similarly-lined tubular extension may be mounted downstream of the throat and flexed periodically to loosen any matter deposited therein. An orifice may be mounted in a diaphragm upstream of the throat to move in response to liner flexure for limiting solid matter accumulation adjacent the throat inlet.
