ABSTRACT:
A freeze concentrator of the shell and tube type containing a pool of liquid cryogen within the shell, the concentrator being adapted to maintain a constant temperature within the liquid cryogen. The temperature control comprises a flash tank located above the level of liquid cryogen within the concentrator, to which the vapors evolved from the boiling cryogen are passed. The flash tank is provided with a condenser for condensing the cryogen vapor which enters the flash tank, the resulting liquid cryogen collecting within the flash tank and being recycled therefrom by gravity to the pool of cryogen in the exchanger.
