ABSTRACT:
The present invention relates to process and apparatus for regenerating low temperature, low pressure energy from the vaporization of a primary fluid having a high boiling point and a large latent heat of vaporization to high pressure, high temperature energy which can then either be fed back to that same primary fluid or put to other uses. The process comprises interacting the primary fluid with a heat recycling fluid consisting of a solution of two basic fluids, a solute and a solvent. The solvent has a low boiling point and a large latent heat of vaporization, while the solvent has a high boiling point. The solute and the solvent have a high affinity for one another. The heat recycling fluid takes up the latent heat of vaporization of the primary fluid to separate the solute from the solution and thereby produce an endothermic reaction. The solute is subsequently forced back into solution in the solvent in an exothermic reaction which liberates the latent heat of vaporization of the solute in the form of sensible heat energy usable for heating the recycling fluid. After being heated, the recycling fluid may be interacted with either the primary fluid or used as a heat source any other heat using process.
