1. An apparatus for recovering a liquid product from a liquid mixture, said apparatus comprising:
- an outer housing defining a vacuum chamber located within said housing;
a material-collection trough located within said housing and defining at least in part a vaporization zone of said vacuum chamber and a channel into which non-vaporized material originally contained in said liquid mixture is collected, said trough further defining a vapor passage for a vapor product exiting said vaporization zone;
one or more liquid mixture supply conduits located within said vaporization zone and extending along at least a portion of the length thereof, each of said conduits comprising one or more nozzles operable to introduce the liquid mixture into said vaporization zone as a plurality of finely dispersed droplets, at least a portion of the liquid mixture contained within said droplets being vaporized within said vaporization zone to form the vapor product, said channel being configured to collect any portion of the liquid mixture not vaporized in said vaporization zone;
a gas-handling apparatus operable to dissolve a gas component into the liquid mixture, said gas component becoming liberated from the liquid mixture as the liquid mixture is vaporized within said vaporization zone; and
a condensing structure located within said housing in disposition to contact and condense at least a portion of the vapor product exiting said vaporization zone through said vapor passage thereby forming the liquid product.

Abstract
Apparatus, methods, and systems for separating a fluid mixture are provided which employ gas-handling equipment operable to introduce a gas into the liquid mixture prior to being dispersed within the apparatus, vacuum conditions, and internal condensing. The liquid mixture is dispersed within the separation apparatus as micro-sized droplets. A more volatile portion of the liquid mixture is vaporized when exposed to the vacuum conditions and separates from the non-vaporized liquid portion. The vaporized portion is directed to a condensing structure within the apparatus, which condenses the vaporized portion into a liquid product.

10. A system for recovering a liquid product from a liquid mixture comprising a most volatile fraction, a less volatile fraction, and a least volatile fraction, the less volatile fraction comprising the predominant component of the liquid mixture, said system comprising:
-
a first gas-handling apparatus operable to introduce a first gas component into the liquid mixture so as to cause at least a portion of the first gas component to become dissolved within the liquid mixture; a first separation apparatus located downstream from said first gas-handling apparatus and operable to separate the most volatile fraction from the less volatile fraction and least volatile fraction, said first separation apparatus comprising; a first outer housing defining a first vacuum chamber located within said first housing, a first fluid-collection trough located within said first vacuum chamber and defining at least in part a first vaporization zone of said vacuum chamber and a first channel into which liquid may be collected, said first trough further defining a first vapor passage for a most volatile fraction vapor product exiting said first vaporization zone, and one or more nozzles located within said first vaporization zone and operable to introduce the liquid mixture into said vaporization zone as a plurality of finely dispersed droplets, at least a portion of the liquid mixture contained within said droplets being vaporized within said first vaporization zone to form the most volatile component vapor product, said first channel being configured to collect any portion of the liquid mixture not vaporized in said first vaporization zone and deliver the non-vaporized portion from said first trough and said first housing as an enriched liquid mixture; a second gas-handling apparatus located downstream from said first separation apparatus and operable to introduce a second gas component into the enriched liquid mixture from said first separation apparatus so as to cause at least a portion of said second gas component to become dissolved within the enriched liquid mixture; and a second separation apparatus located downstream from said second gas-handling apparatus and operable to separate a portion of the less volatile fraction the least volatile fraction, said second separation apparatus comprising; a second outer housing defining a second vacuum chamber located within said second housing, a second fluid-collection trough located within said second vacuum chamber and defining at least in part a second vaporization zone of said second vacuum chamber and a second channel into which liquid may be collected, said second trough further defining a second vapor passage for a less volatile fraction vapor product exiting said second vaporization zone, one or more nozzles located within said second vaporization zone and operable to introduce the enriched liquid mixture into said second vaporization zone as a plurality of finely dispersed droplets, at least a portion of the enriched liquid mixture contained within said droplets being vaporized within said second vaporization zone to form the less volatile fraction vapor product, said second channel being configured to collect any portion of the enriched liquid mixture not vaporized in said second vaporization zone, and a condensing structure located within said second housing in disposition to contact and condense at least a portion of the less volatile fraction vapor product exiting said second vaporization zone through said second vapor passage thereby forming said liquid product. - View Dependent Claims (11, 12, 13)
