Abstract: A polymeric membrane made of a polyimide polymer or copolymer essentially consisting of repeating units of dianhydride-derived units and diamine-derived units. At least some of the dianhydride-derived units are derived from 2,2-bis(3,4-dicarboxyphenyl)hexafluoropropane (6FDA). At least some of the diamine-derived units are derived from 2,5-diethyl-6-methyl-1,3-diamino benzene (DETDA). The balance of the diamine-derived units are derived from a diamino benzene ring with a carboxylic acid substituent.
Abstract: A method and burner for combusting fuels having a heating value of <80 BTU/scf (<2.98 MJ/Nm3) in which the fuel premixed with air is injected into a porous inert media so that the fuel is combusted with the air. Oxygen may be optionally injected into the porous inert media separately from the premixed air/fuel.
Abstract: Methods and apparatus for processing a metal using a hybrid burner are described herein. The costs of melting and refining metal, such as iron, using standard burners is subject to fluctuation. The hybrid burners described herein are capable of burning both standard fuels as well as solid carbon-containing fuels, like coal. Through the use of a hybrid burner in either standard or modified electric arc furnaces, the costs for melting and refining an iron source can be reduced both through the costs of fluid hydrocarbon fuel sources and through the reduced or eliminated need for external carbon sources during refining.

Abstract: A method of removing contaminants from a gas stream utilizing a supersonic venturi including a converging section, a throat, and a diverging section is provided. A contaminated gas stream and a scrubbing liquid stream are introduced into the converging section, thereby forming a mixed stream which experiences choked flow upon exiting. The choked mixed stream is introduced into the throat section wherein the scrubbing liquid is contacted with the contaminated gas stream. The contaminated scrubbing liquid stream is removed from the supersonic venture scrubber, and an essentially pure gas stream is removed from the diverging section. A flow modification device may be introduced into the throat section. The flow modification device may be either axially or radially adjustable in order to effect the atomization of the scrubbing liquid and/or the contacting of atomized scrubbing liquid with the contaminated gas stream within the throat section.

Abstract: Embodiments of the invention generally provide methods and systems that distribute an additive in solid carbon dioxide in an interior of food processing equipment. The additive may be injected into a flow of liquid carbon dioxide upstream of an expander at or adjacent to the interior. Injection of the additive into the interior may be alternated with directing a flow of expanded carbon dioxide into the interior. In some embodiments, the freezing point of the additive with or without a diluent composition and/or additive(s) is lower than a temperature of the liquid carbon dioxide.

Abstract: An apparatus and method for holding a solid precursor in a sublimator such that the solid precursor can be vaporized for saturating a carrier gas. The apparatus may include alternating disks or shelves that form inner and outer passages, as well as spaces between the disks for fluidicly coupling the passages to create a winding, tortuous fluid flow path through the sublimator for optimizing solid vapor saturation. The method may include directing a carrier gas into a sublimation chamber, around the first shelf in the outer passage, over the first shelf in the space, around the second shelf in the inner passage, and back out of the sublimation chamber.

Abstract: Temperature overshoot of internal components of a counter-flow shell and tube heat heat exchange may be reduced or avoided by adjusting the degree to which a tube-side fluid partially bypasses the heat exchanger.
Abstract: A burner has a fuel/oxidant nozzles and a pair of dynamical lances spaced on either side thereof that inject a jet of fuel and primary oxidant along a fuel injection axis, and jets of secondary oxidant, respectively. Jets of actuating fluid impinge against the jets of secondary oxidant to fluidically angle the jets of secondary oxidant away from the fuel injection axis. The action of the angling away together with staging of the oxidant between primary and secondary oxidant injections allows achievement of distributed combustion conditions.
