Patent number: 7696396Abstract: Carotenoids are extracted and/or enriched from a mixture containing such compounds. The extraction/enrichment process involves the use of liquefied or supercritical solvents to extract lipids and carotenoids from carotenoid-containing substrates. The extraction process can also be performed in two steps in which lipids and carotenoids are first removed from a carotenoid-containing substrate with a liquefied or supercritical solvent, and subsequently a liquefied or supercritical gas is used to separate the lipids from the carotenoids. The two step process can be reversed to first extract lipids with the liquefied or supercritical gas, and subsequently use the solvent to extract the carotenoids. The process is also applicable to yield an organic solvent-free product from a carotenoid-containing source that was first extracted using an organic solvent.Type: GrantFiled: January 9, 2008Date of Patent: April 13, 2010Assignee: Phasex CorporationInventors: Hans Schonemann, Anthony Gudinas, Kara Williams, Paula Wetmore, Val Krukonis

Patent number: 5389263Abstract: Disclosed is a process for recrystallizing materials that are ordinarily difficult-to-comminute. The process utilizes supercritical fluids and gasses at conditions near their respective vapor pressures which have the ability to dissolve in and expand liquid solutions. The process has been shown to be particularly effective at separating HMX and RDX thereby resulting in a precipitate of RDX which is essentially free of HMX.Type: GrantFiled: May 20, 1992Date of Patent: February 14, 1995Assignee: Phasex CorporationInventors: Paula M. Gallagher, Val J. Krukonis, Michael P. Coffey

Patent number: 5360478Abstract: Disclosed is a method for recrystallizing solid materials (e.g. RDX) from systems comprised of a solute, which is the eventual material recrystallized, a liquid which is a suitable solvent for the solute, and a gaseous component which is soluble within the solvent and whose presence therein causes the solvent to approach or attain a supersaturated state, thereby precipitating (recrystallizing) the solute material. By control of process parameters (pressure, temperature, time, and rate, rate of injection of gas, etc.) the operator can influence the properties of the material recrystallized.Type: GrantFiled: June 28, 1991Date of Patent: November 1, 1994Assignee: Phasex CorporationInventors: Val J. Krukonis, P. M. Gallagher, M. P. Coffey
