Abstract: An apparatus is provided for extracting compounds from mixtures based on their relative solubilities in different solvents. The mixture can be introduced into a cylindrical container in which the mixture is agitated as it flows past a plurality of plates mounted along a shaft. At least one plate is arranged at a nonzero angle with respect to a plane normal to the shaft and features a plurality of perforations. Agitation by the plates breaks the mixture into small, evenly dispersed droplets and a solvent is introduced into the container to extract the desirable compound and thus separate it from the undesirable compounds.

Abstract: A vane inlet apparatus is provided for separating components of a feed stream. The apparatus includes a body having an axis, a proximal end, and a distal end. The body includes an inlet and a plurality of vanes disposed along the axis. Each vane includes an aperture such that the apertures in successive vanes decrease in size toward the distal end of the apparatus. The vanes may be flat or curved. The sizes, shaped, and orientation of the vanes along the apparatus may be determined according to the designed specifications of a particular project. The apparatus as well as the vanes and apertures are preferably cylindrically shaped to match the incoming feed stream cross-section. A method of constructing the vane inlet apparatus is also provided.

Abstract: A process for vitrifying waste material containing environmentally hazardous metals or metal compounds includes drying a waste material using a flash dryer, where the drying is carried out at a temperature low enough to prevent volatilization of hazardous metals and metal compounds contained in the waste material. Preferably, more than about 95% of the water is removed form the waste material. The dried waste material is transferred from the flash dryer into a melting vessel, melted, collected and cooled to form a vitrified mass of waste material. Gases produced during the process of the invention are filtered, treated, and released into the atmosphere.

Abstract: A chemically derived product that rusts metal instantly upon contacting the surface of a metal and which can be easily and safely used by ornamental metal craftpersons. The chemically derived product is a liquid compound that contains the following constituents: (a) 93.0% by weight of water; (b) up to 5.0% by weight of a copper salt, the copper salt being selected from a copper salt group consisting of copper sulfate, copper nitrate, and copper chloride; and (c) a remaining amount consisting of an acid compound selected from an acid compound group consisting of sulfamic acid, oxalic acid, hydrochloric acid and nitric acid. The liquid compound can be particularly formulated for oxidizing steel or copper and may be produced having a predetermined coloring dye constituent selected from a color dye group consisting of copper, auburn, or gold, if oxidizing steel, or a color dye selected from a color dye group consisting of patina, aqua blue, or green, if oxidizing copper.

Abstract: An electrochemical process and system for dehalogenating halogenated hydrocarbons. The process facilitates on-site processing and transformation of waste oils, PCB oils in electrical transformers and chlorinated solvents to salts. The system includes a two-piece tubular structure including an electrical insulating member, an electrode member having perforations leading into a hollow vessel portion. The process includes, by example, reacting the halogenated hydrocarbon compound with at least one metal hydroxide selected from a metallic hydroxide group consisting of sodium hydroxide, calcium hydroxide, zinc hydroxide, and potassium hydroxide in the presence of an alcohol selected from an alcohol group consisting of methanol, ethanol, or isopropanol. The tubular structure is inserted into the container and energized by applying a voltage to the electrode member.

Abstract: A liquid extraction process using counterflowing liquid phases in a reciprocating plate extraction column in which the plates of the column are spaced with respect to one another approximately according to the equation: ##EQU1## wherein l is the plate spacing, U.sub.D is the superficial velocity of the dispersed phase at flooding, U.sub.C is the superficial velocity of the continuous phase at flooding, .DELTA..rho. is the density difference and .sigma. is the interfacial tension.By using the above equation the volume of column required to carry out a specific extraction is minimized.The extraction column comprises a casing, a reciprocating shaft in the casing having perforated plates and, optionally, baffle plates mounted thereon in a spatial relationship with respect to each other calculated on the basis of the equation and includes motive means and suitable cam and driving means to reciprocate the shaft.
