  • Glycol solvents and process
    Patent number: 6177597
    Abstract: A glycol solvent selected from a glycol and a tetramethylammonium carboxylate having improved dehydrating capacity and a reduced aborbency for aliphatic and aromatic hydrocarbons.
    Type: Grant
    Filed: July 6, 1999
    Date of Patent: January 23, 2001
    Assignee: Gavlin Associates, Inc.
    Inventors: Gilbert Gavlin, Boris Goltsin
  • Glycol solvents and method thereof
    Patent number: 5853458
    Abstract: A solvent composition comprising a glycol, a potassium carboxylate and a neopentyl alcohol having improved dehydrating capacity and reduced absorbency for aliphatic and aromatic hydrocarbons.
    Type: Grant
    Filed: August 18, 1997
    Date of Patent: December 29, 1998
    Assignee: Gavlin Associates, Inc
    Inventors: Gilbert Gavlin, Boris Goltsin
  • Gas dehydration process
    Patent number: 5725637
    Abstract: A process for dehydrating gaseous fluids, such as natural gas, in which the gaseous fluid is contacted with a dehydrating composition having a glycol and a dissolved salt of at least one alkali metal carboxylate. The glycol is preferably ethylene glycol, diethylene glycol, triethylene glycol and mixtures thereof. The dissolved salt preferably constitutes up to about 33% by weight of the dehydrating composition.
    Type: Grant
    Filed: October 31, 1996
    Date of Patent: March 10, 1998
    Assignee: Gas Research Institute
    Inventors: Gilbert Gavlin, Boris Goltsin
  • Gas dehydration process
    Patent number: 5725636
    Abstract: A process for dehydrating gaseous fluids, such as natural gas, in which the gaseous fluid is contacted with a substantially anhydrous composition having a glycol and an aromatics solubility depressant. The glycol is preferably ethylene glycol, diethylene glycol, triethylene glycol, and mixtures thereof.
    Type: Grant
    Filed: September 26, 1996
    Date of Patent: March 10, 1998
    Assignee: Gas Research Institute
    Inventors: Gilbert Gavlin, Boris Goltsin
  • On-site, controlled waste concentrator and solvent regenerator apparatus
    Patent number: 5334291
    Abstract: An apparatus for removing non-volatile residues and impurities from a used solvent includes a self-scrubbing heating distillation subassembly for separating purified solvent for reuse and a controlled waste collector subassembly for overflowing concentrated residues and impurities stripped from the used solvent into an easy-to-service container. The apparatus may be disposed in a parallel in-line relationship with a circulating solvent flow circuit, such as in a dry cleaning operation, to continuously withdraw and purify aliquot portions of the circulating solvent stream, returning good solvent back to the flow circuit and concentrating non-volatile residues and impurities to a removable, environmentally sound serviceable container.
    Type: Grant
    Filed: July 9, 1993
    Date of Patent: August 2, 1994
    Assignee: Safety-Kleen Corp.
    Inventors: Gilbert Gavlin, William M. Langdon, deceased, Boris Goltsin, Gunther Erlebacher, Douglas A. Larson
  • Purification of isoflurane by extractive distillation
    Patent number: 5230778
    Abstract: A method for the separation of Isoflurane from its admixture with other compounds produced in the chlorination of 2-difluoromethoxy-1,1,1-trifluoroethane including subjecting the mixture to distillation, distilling off the Isoflurane and effecting said distillation as an extractive distillation employing an extractive solvent which retards the vapor pressure of Isoflurane.
    Type: Grant
