    • The present invention provides methods and systems for the extraction of solutes from solid matter using dense gases in a mechanical auger separation system, the method comprising: a) passing the insoluble composition comprising solute into a pressurized inclined housing containing an auger; b) combining the insoluble composition with a solvent gas in either the supercritical or liquid phase to dissolve the solute c) maintaining pressure in the housing sufficient to create a biphasic dense gas comprising a vapor phase and a liquid phase; and d) rotating the auger to promote the separation of the insoluble composition from the solute; whereby the solute and the liquid phase o the dense gas flow to the bottom of the auger for removal and the insoluble composition and vapor phase of the dense gas move to th top of the auger for removal, thereby separating the solute from the Insoluble composition.
    • 本发明提供了用于在机械螺旋分选系统中使用致密气体从固体物质中提取溶质的方法和系统,所述方法包括:a)使包含溶质的不溶性组合物进入含有螺旋钻的加压倾斜壳体; b)将不溶性组合物与超临界或液相中的溶剂气体混合以溶解溶质c)保持壳体中的压力足以产生包含气相和液相的双相致密气体; 和d)旋转螺旋钻以促进不溶性组分与溶质的分离; 由此致密气体中的溶质和液相流到螺旋钻的底部以除去,并且致密气体的不溶性组成和气相移动到螺旋钻的顶部以除去,从而将溶质与不溶物组合物分离。
