ABSTRACT:
A process for liquifying a substance comprises: (a) transferring latent heat from the substance in the gaseous state to a first heat transfer fluid passing through a first loop wherein the first heat transfer fluid is substantially isolated from the substance and is unreactive with the substance; (b) transferring heat from the first heat transfer fluid to a second heat transfer fluid passing through a second loop wherein the second heat transfer fluid is substantially isolated from the substance and from the first heat transfer fluid; and (c) transferring heat from the second heat transfer fluid to a third heat transfer fluid wherein the third heat transfer fluid is substantially isolated from the substance, from the first heat transfer fluid, and from the second heat transfer fluid. The preferred substance is molecular chlorine.
