Heat-regenerative separator and method
Abstract
Abstract A heat-regenerative separator and method which uses a heat-regenerative element having a heat-regenerative material at phase-change temperature to impart to or receive from an input fluid latent heat of separation thereby causing separation from said input fluid a product of a phase different than the input fluid which product will subsequently be withdrawn from the separation area in a withdrawal fluid when said heat-regenerative material receives from or imparts to said withdrawal fluid latent heat of decomposition of said product into said withdrawal fluid, said method comprising alternating passage of input fluid and withdrawal fluid in heat-exchange relation with said heat-regenerative element.
