Abstract:
1. Process for use with a flow of a liquid mixture that is separable by vaporization into a flow of vapor and a depleted flow of liquid, the process comprising: a vaporization step, wherein a portion of said liquid mixture flow is vaporized to produce said flow of vapor and said depleted flow of liquid; an absorption step, wherein (i) the flow of vapor is introduced to a flow of brine which is adapted to exothermically absorb one or more components from the vapor and (ii) heat is withdrawn, to produce at least a flow of heat and a flow of brine which is enriched in the one or more components; and a heat transfer step, wherein the heat withdrawn in the absorption step is transferred, to drive the vaporization in the vaporization step, wherein the transfer of heat to drive the vaporization is associated with the phase change of a working fluid from a gaseous state into a liquid state; the withdrawal of heat in the absorption step involves the phase change of the working fluid from the liquid state into the gaseous state; in the liquid state, the working fluid flows only by one or more of gravity, convection and wicking; and in the gaseous state, the working fluid flows only by one or more of diffusion and convection.
