  • Method and composition for the removal of ammonium salt and metal compound deposits
    Patent number: 4793865
    Abstract: Amines are injected in hydrocarbon processing units to remove and/or to prevent the formation of ammonium salt deposits. Furthermore, oxygen containing hydrocarbon compounds are injected in hydrocarbon processing units to remove metal compound deposits. The amines and/or the oxygen containing compounds may be injected alone or in combination. Furthermore, the amines and/or the oxygen containing compounds may be used in combination with filming agents that are suitable for corrosion control in such units.

  • Manufacture of refrigeration oils
    Patent number: 4304660
    Abstract: Lubricating oils suitable for use in refrigeration equipment in admixture with fluorinated hydrocarbon refrigerants are produced by solvent extraction of naphthenic lubricating oil base stocks, cooling the resulting extract mixture, optionally with the addition of a solvent modifier, to form a secondary raffinate and a secondary extract, and recovering a dewaxed oil fraction of lowered pour point from the secondary raffinate as a refrigeration oil product.The process of the invention obviates the need for a separate dewaxing operation, such as dewaxing with urea, as conventionally employed for the production of refrigeration oils.
