System for recovering and condensing vapors

A system for recovering and condensing vapors from a liquid storage tank, said system comprising a shell, means connecting the storage tank to said shell for permitting the vapors in said tank to pass into said shell, an inner liner disposed in said shell for receiving said vapors, a packing material disposed in said liner through which said vapors pass, a vortex tube adapted for connection to a source of compressed air and adapted to convert said air into a stream of cold air, a helical tube connected to said vortex tube and extending around said liner so that cold air is passed through said tube in a heat exchange relation to said vapors to condense said vapors, and means for passing said condensed vapors back to said storage tank.

A system for recovering and condensing vapors from a liquid storge tank, said system comprising a shell, means connecting the storage tank to said shell for permitting the vapors in said tank to pass into said shell, an inner liner disposed in said shell for receiving said vapors, a packing material disposed in a space defined between said inner liner and said shell, a vortex tube adapted for connection to a source of compressed air and adapted to convert said air into a stream of cold air, a helical tube connected to said vortex tube and extending in said space so that said cold air is passed through said tube in a heat exchange relation to said vapors to condense said vapors, and means for passing said condensed vapors back to said storage tank.

A system for recovering and condensing vapors from a liquid storage tank, said system comprising a shell, means connecting the storage tank relative to a lower portion of said shell for permitting the vapors in said tank to pass into said shell and through said shell in an upwardly direction, a vortex tube adapted for connection to a source of compressed air and adapted to convert said air into a stream of cold air, means connected to said vortex tube for passing said cold air through said shell in a heat exchange relation to said vapors to condense said vapors, and means for passing said condensed vapors in said shell back to said storage tank in a generally downwardly direction under the force of gravity to absorb a portion of the upwardly passing vapors.
