Condensing ammonia, natural gas and fluoro-chloro-hydrocarbon(s) - in simple washing-condenser plant, including prepn. for storage and transportation

摘要

This is a method of condensing vapour from industrial process. By material exchange processes in a washing condenser where it is washed in counterflow with a fluid having a higher boiling points. the cold vapour is converted to the higher b.pt. vapour of the washing fluid. The cold vapour becomes liquified, and the vapour from the higher b.pt. fluid is liquefied in a heat exchanger. The heat exchanger can be installed in the vapour outlet pipe from the condenser. USE/ADVANTAGE - Used for the liquefaction of cold vapours such as ammonia, natural gas, and FCKW, and includes the cooling of pressing vessels in which the cold vapours are stored and transported, and also the evacuation of parts of the plant that contain these gases. The complications of earlier methods of condensing these vapours are avoided.
