Abstract: A spray-drying apparatus includes a drying chamber that has a first end, a second end, and at least one side wall extending between the first and second ends to define an interior of the drying chamber having a center axis. A nozzle can be positioned at the first end of the drying chamber and be configured to atomize liquid and spray the atomized liquid into the interior of the drying chamber at a maximum spray pattern angle relative to the center axis. A heating device can be provided to heat the liquid prior to introduction into the drying chamber.

Abstract: A process for removing and recovering a condensable vapor from a gas stream by a membrane contactor is disclosed wherein a gas stream containing a condensable vapor is circulated on one side of hollow fiber membranes while cool extraction fluid is circulated on the other side under a total pressure differential, thereby condensing the condensable vapor in the gas stream, the condensed vapor permeating the membrane and becoming entrained in the cool extraction fluid.

Abstract: Hybrid membrane-based separation systems are disclosed that are useful in separating solvents and solutes. The hybrid systems combine any of the solvent removal processes reverse osmosis, nanofiltration, membrane distillation and pervaporation with any one of more of the solute removal processes utilizing pervaporation membranes, supported-liquid membranes, coupled transport membranes, and membrane contactors, the solvent and solute removal processes forming part of a recycle stream that utilizes membrane separation retentates as feeds and as recycle feed stream make-up.

Abstract: The process comprises delivering a spray solution comprising an active agent and a matrix material in an organic solvent to a spray-drying apparatus, atomizing the spray solution into droplets within the spray-drying apparatus to remove at least a portion of the organic solvent from the droplets to form a plurality of particles, and collecting the particles. The spray solution may be formed by forming a feed suspension comprising the active agent, the matrix material, and the organic solvent, wherein the feed suspension is at a temperature T1, and directing the feed suspension to a heat exchanger, thereby increasing the temperature of the feed suspension to a temperature T2, wherein T2 is greater than T1, and the spray solution is at a pressure greater than the vapor pressure of the organic solvent at T2, such that the active agent and matrix material are soluble in the organic solvent at T2.

Abstract: 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.
