Abstract: Apparatus is disclosed for the production of nitrogen trifluoride (NF.sub.3), starting with an anhydrous molten flux including ammonia (NH.sub.3), a metal fluoride (MF), and hydrogen fluoride (HF). The apparatus includes an electrolyzer, an ammonia solubilizer, a hydrogen fluoride solubilizer, a nitrogen trifluoride reactor, two compressors, two pumps, three condensers a gas recycle loop, and, two flux loops of the same component ternary flux, but each loop with different concentration.

Abstract: An electrolyzer, including a lower electrolyte chamber for receiving liquid electrolyte flux and having disposed therein anode and cathode electrodes for producing anodic and cathodic gases. A first barrier is disposed in the lower electrolyte chamber between the anode and cathode electrodes having a plurality of V-shaped passageways for allowing the passage of electrons but for preventing the recombination of anodic and cathodic gases. The electrolyzer also includes an upper gas chamber having an anodic gas compartment and a cathodic gas compartment for receiving therein the anodic and cathodic gases produced in the lower electrolyte chamber. The upper gas chamber includes a second barrier disposed between the anodic and cathodic gas compartments having no passageways in order to prevent the recombination of anodic and cathodic gases. The second barrier is connected to the first barrier.

Abstract: A method for the production of nitrogen trifluoride (NF.sub.3) and hydrogen (H.sub.2) gas, starting with a molten flux including at least ammonia (NH.sub.3), a metal fluoride, and hydrogen fluoride (HF), including the steps of: circulating the molten flux from an electrolyzer, to an ammonia solubilizer, to a nitrogen trifluoride reactor, to a hydrogen fluoride solubilizer, and back to the electrolyzer; maintaining the quantity of the molten flux substantially constant by adding ammonia (NH.sub.3) and a carrier gas to the ammonia solubilizer and by adding hydrogen fluoride (HF) and a carrier gas to the hydrogen fluoride solubilizer; producing fluorine (F.sub.2) gas and hydrogen (H.sub.

Abstract: The present invention relates to a method and apparatus for direct fluorination of hydrocarbons (having 1 to 4 carbons) by using molecular fluorine gas in a liquid medium. The number of reactors or reaction steps is a function of the number of hydrogen atoms in the hydrocarbon to be replaced by molecular fluorine to produce a refrigerant or other product.

Abstract: A gas-scrubber apparatus, including a chamber having an inlet means for receiving polluted gases to be scrubbed and having outlet means through which scrubbed gases are discharged, and heating elements for heating the chamber to maintain the polluted gases at predetermined temperature levels between the inlet means and the outlet means. The chamber includes a reaction zone for receiving a mixture of solid scrubbant materials for reacting with the polluted gases and a gas blower for directing the polluted gases to travel through the chamber to react with the scrubbant materials. At least one scrubber assembly is mounted in the reaction zone of the chamber having a baffle for collecting the polluted gases in the area adjacent the wall of the chamber.

Abstract: The present invention provides an electrolytic gas generator for generating fluorine and other chemicals and more particularly, to a more efficient electrolyzer having reduced resistance between the cathode and anode and which prevents the migration of gas between the anode compartment and the cathode compartment.

Abstract: An apparatus for forming a tube including a base, a pair of legs secured to the ends of the base, and a holder base attached to the base. A tube holder for holding the tube is connected to the holder base. The tube holder has a structure defining a pair of diametrically opposed openings. A pair of soldering irons is oppositely secured with respect to each other in proximity to the top of the pair of legs. Each soldering iron has a hot end that generally registers with one of the opposed openings such as to be in close proximity to the tube being held by the tube holder in order to soften the material of the tube in the area contiguous to the openings. Power is conducted and supplied to each of the soldering irons. Vacuum is drawn on top of the tube to suck or pull inward the tube in the spots being softened from the heat of the pair of soldering irons.
