Abstract
A system for recovering and condensing vapors from a liquid process or storage tank in which a shell is connected to the tank for receiving the vapors from the tank, and a vortex tube is adapted to supply a stream of cold air into said shell. The cold air is passed in a heat exchange relation to the vapors in said shell to condense the vapors, and the condensed vapors are passed back to the tank.
