  • Removal of naphthalene from recirculated wash oil
    Patent number: 4286971
    Abstract: A bleed stream from the recirculating wash oil in a final cooling system for coke oven gas is centrifugally separated into a waste water stream, a sludge stream and a clean, dry oil stream which is substantially free of solids and has a water content less than 0.5% (wt.). The clean, dry oil stream is heated to less than about 160.degree. C., preferably 125.degree.-135.degree. C., before entering a naphthalene stripper-wash oil still.
    Type: Grant
    Filed: October 5, 1979
    Date of Patent: September 1, 1981
    Assignee: Bethlehem Steel Corporation
    Inventors: Kenneth R. Burcaw, Jr., Robert E. Watkins, Jr.
  • Cooling naphthalene-bearing waters and gas streams
    Patent number: 4234389
    Abstract: A method for cooling naphthalene containing gas streams using recirculated cooling water comprising physically separating suspended naphthalenic solids from the used cooling water, injecting a water immiscible solvent for naphthalene into the clarified cooling water, and vigorously mixing the solvent and cooling water to form a dispersion which is recooled in an indirect heat exchanger without serious buildup of naphthalenic solids in the heat exchanger and recycled to cool the gas stream.
    Type: Grant
    Filed: February 21, 1979
    Date of Patent: November 18, 1980
    Assignee: Bethlehem Steel Corporation
    Inventors: James B. Lynn, Otto A. Homberg, Kenneth R. Burcaw, Jr.
  • Process for the distillation of weak ammonia liquor
    Patent number: 4108734
    Abstract: The fouling of ammonia stills which results from the clogging, particularly of the lower plates of the stills, with sludge and precipitates is eliminated by use of a calcium compound precipitation step followed by a clarification step prior to initiation of actual distillation.
    Type: Grant
    Filed: June 14, 1976

  • Method for improved distillation of ammonia from weak ammonia liquor
    Patent number: 4108735
    Abstract: Fouling of an ammonia still, used for removal of ammonia from weak ammonia liquor derived from a coal coking operation, is alleviated by pre-precipitating insoluble calcium salts from the ammonia liquor by treatment of the liquor with lime prior to introduction into a single-leg still.
