  • Treatment of lower glycol-containing operative fluids
    Patent number: 5194159
    Abstract: Operative fluids containing lower glycol are contacted with semi-permeable membranes under reverse osmosis conditions to permeate lower glycol to provide a reclaimed lower glycol product. Exemplary operative fluids include antifreeze solutions, heat transfer fluids, deicers, quenchants, hydraulic fluids, lubricants, solvents and absorbents.
    Type: Grant
    Filed: December 18, 1991
    Date of Patent: March 16, 1993
    Assignee: Union Carbide Chemicals & Plastics Technology Corporation
    Inventors: Kathleen F. George, Lise Dahuron, John H. Robson, George E. Keller, II, Benjamin Bikson

  • Treatment of impurity-containing liquid streams in ethylene oxide/glycol processes with semi-permeable membranes
    Patent number: 5034134
    Abstract: A method is disclosed for separating impurity components, UV absorbers and/or UV absorber precursors contained in an ethylene glycol-water stream thereby desirably allowing the recovery of the glycols contained in such stream in an economical and efficient manner. Specifically, these undesirable components are separated by contacting the ethylene glycol-water stream with a suitable semi-permeable membrane to effect such separation.

  • Catalyst composition for polymerizing ethylene
    Patent number: 5019633
    Abstract: Catalyst compositions suitable for producing high density ethylene polymers in a low pressure gas phase process with low accompanying ethylene hydrogenation are produced by forming a precursor composition from a magnesium compound, titanium compound and electron donor compound; diluting said precursor composition with an inert carrier material; treating said diluted precursor compositon with a boron halide compound; and activating the precursor composition with an organo aluminum compound.

    Assignee: Technology Corporation
    Inventors: Burkhard E. Wagner, George L. Goeke, Frederick J. Karol, Kathleen F. George
  • Triethylene glycol-based heat transfer fluids
    Patent number: 4758367
    Abstract: Single-phase, thermally-stable, corrosion-inhibiting heat transfer fluids comprising triethylene glycol, a corrosion-inhibiting amount of a mixture of a soluble borate compound and a soluble Group VIa metal oxygenate compound selected from the group consisting of chromate, molybdate and tungstate compounds, and, optionally, water, a copper corrosion inhibitor and sodium nitrate.

  • Catalyst composition for copolymerizing ethylene
    Patent number: 4370456
    Abstract: Ethylene copolymers having improved resistance to pinstriping and gel streaking when extruded into film can be produced by continuously copolymerizing ethylene with one or more higher alpha olefin monomers in a low pressure gas phase reaction with a catalyst composition prepared by forming a precursor composition from a magnesium compound, titanium compound, and electron donor compound; diluting said precursor composition with a silica support which has been treated with a dialkylzinc compound; and activating the diluted precursor composition with an organoaluminum compound.
