Described herein is a method of maintaining corn protein yield during extraction, comprising obtaining a corn gluten material, washing the corn gluten material to remove non-protein components with an ethanol-water solvent comprising at least 85 wt % ethanol to obtain a corn protein concentrate product, wherein the loss of corn protein content during extraction is less than 25% of total corn protein.

The present invention concerns a process for removing carbon monoxide and/or gaseous sulphur compounds from hydrogen gas and/or aliphatic hydrocarbons, preferably at low temperatures, with the aid of complex metal aluminium hydrides.

Composite materials and methods of preparing C0.sub.2 capture include: (1) a porous solid support comprising a plurality of porous channels; and (2) a nucleophilic source associated with the porous channels of the porous solid support. The nucleophilic source is capable of converting the captured C0.sub.2 to poly(C0.sub.2). Methods of capturing C0.sub.2 from an environment include associating the environment with the aforementioned composite materials to lead to the capture of C0.sub.2 from the environment. Such methods may also include a step of releasing the captured C0.sub.2 from the composite material. The associating step comprises a conversion of the captured C0.sub.2 to poly(C0.sub.2) in the composite material. A releasing step may also include a depolymerization of the formed poly(C0.sub.2).

The present invention relates to a method for the purification of alkanes, especially methane, wherein an alkane comprising impurities, especially methane, is reacted with an active compound, optionally in the presence of sulfur trioxide, whereby the impurities are removed. The present invention furthermore relates to the use of the active compound and sulfur trioxide in the purification of alkanes, especially methane.

The present invention describes methods for absorbing a targeted chemical compound from a gas stream into a scrubbing solution for various uses and with various benefits. Methods are described to produce a gas stream that can be further processed with operational benefits, such as through condensing and wastewater treatment with a lower load on the wastewater treatment system. Methods are described for adsorbing the targeted compound with reduced condensation of water from the gas stream. Methods are described for producing a liquid stream comprising an absorbed form of the targeted compound for use as a saleable product, such as adsorbing ammonia for the production of a fertilizer, wherein the concentration of the absorbed form may be increased through reduced condensation from the gas stream.

Methods are described for producing a lower volume liquid waste stream from the absorption process through the use of reduced condensation of the gas stream.

A gas purification device includes: a converter packed with a catalyst for hydrolyzing both carbonyl sulfide and hydrogen cyanide; an upstream heat exchanger for heat exchange between a gas to be introduced into the converter and a cooling fluid for cooling the gas; a reaction-temperature estimation member for estimating a reaction temperature inside the converter; and a flow-rate adjustment member for adjusting a flow rate of the cooling fluid flowing into the upstream heat exchanger based on an estimated value of the reaction-temperature estimation member to control the reaction temperature.

A plasma abatement process for abating effluent containing compounds from a processing chamber is described. A plasma abatement process takes gaseous foreline effluent from a processing chamber, such as a deposition chamber, and reacts the effluent within a plasma chamber placed in the foreline path. The plasma dissociates the compounds within the effluent, converting the effluent into more benign compounds. Abating reagents may assist in the abating of the compounds. The abatement process may be a volatizing or a condensing abatement process. Representative volatilizing abating reagents include, for example, CH.sub.4, H.sub.2O, H.sub.2, NF.sub.3, SF.sub.6, F.sub.2, HCl, HF, Cl.sub.2, and HBr. Representative condensing abating reagents include, for example, H.sub.2, H.sub.2O, O.sub.2, N.sub.2, O.sub.3, CO, CO.sub.2, NH.sub.3, N.sub.2O, CH.sub.4, and combinations thereof.
