Abstract
A method of cooling a liquid process fluid in which a liquid process stream is formed from the liquid process fluid and the process fluid contained within the liquid process stream is frozen into a conveyable particulate form. The conveyable particulate form is introduced back into the liquid process fluid. The liquid process fluid can be contained within a container and pumped through a pipe connected to the container to form the liquid process stream. A freezing chamber connected to the top of the container can be provided to countercurrently directly exchange heat between rising vaporized coolant and descending liquid process fluid. The resultant conveyable particulate form can be metered by provision of a valve.
