    摘要： A gas dehydration method and apparatus are disclosed which utilize lumen-side feed, hydrophilic polymer-inside-coated, thin-film composite hollow fiber membranes, the support fiber of which is highly permeable, such composite membranes being used in a module wherein the permeate flows countercurrent to the flow of the feed, and in which dried raffinate gas is mixed with water-containing permeate at a point opposite the feed end of the module.

    摘要： The process comprises delivering a spray solution comprising at least one solute in a solvent to a spray-drying apparatus, using a flash nozzle to atomize the spray solution into droplets within the spray-drying apparatus to remove at least a portion of the solvent from the droplets to form a plurality of particles, and collecting the particles. The spray solution is directed to a heat exchanger, thereby increasing the temperature of the spray solution to a temperature T2, wherein T2 is greater than T1. The flash nozzle comprises a central tube through which the spray solution is delivered and an outer tube through which a sweep gas is delivered. The central tube may have a first outer diameter at an inlet and a second outer diameter at an outlet, wherein the first outer diameter is greater than the second outer diameter.
