  • Automatic refill system for ultra pure or contamination sensitive chemicals
    Patent number: 6604555
    Abstract: A highly reliable and safe, modular automatic refill (bulk delivery) system for ultra-high purity pyrophoric metalorganic chemicals employing: a manifold that insures contamination-free operation; a liquid-level detection system with fail-safe redundancy; and an evacuation system which leaves the system's manifold and transfer lines relatively free of chemical fire hazards; leaves them free of oxygen contamination; and leaves the composition of the system's carrier gas unaffected, between refills.
    Type: Grant
    Filed: August 2, 2002
    Date of Patent: August 12, 2003
    Assignee: Arch Specialty Chemicals, Inc.
    Inventors: Christopher S. Blatt, Richard H. Pearce, Graham Williams, Edward H. Wentworth, III

  • Separation and purification of fluoride from industrial wastes
    Patent number: 5876685
    Abstract: A method for the removal and purification of substantially all of the fluoride ions contained in a solution containing greater than 10 parts per million (ppm) fluoride ion, a mixture of other anions, silicon in the form of a fluorosilicic acid, silicic acid, silicates, or silicon tetrafluoride, and optionally also containing complex metal fluorides, to produce an ultrapure hydrofluoric acid, comprising the steps of (a) adjusting the pH of the solution to an alkaline pH to hydrolyze the fluorosilicic acid and any complex metal fluorides; (b) removing the fluoride ions and other anions from the solution by passing the solution through an ion exchange resin, where the ion exchange resin is adapted to adsorb substantially all of the fluoride passed over the ion exchange resin; (c) displacing the fluoride ions and other anions bound to the ion exchange resin, thereby forming a mixture of anions in an effluent emanating from resin; (d) optionally concentrating the effluent at a high pH and then lowering the pH; and

  • High efficiency chemical processing
    Patent number: 5500095
    Abstract: A high efficiency batch sulfuric acid reprocessor system that is capable of producing high purity acid through distillation. Methods of use are also provided. The distillation is monitored and controlled in accordance with temperatures of the system, in particular, the temperature of the column and the temperature of the vapor in a condensing chamber. A stream splitter enables the invention to selectively collect high purity product as well as remove waste or recycle condensate as reflux.
