Definitions

  • This invention relates to the burning of petroleum fuel oils and high solids content black liquor and, more particularly, it constitutes an improvement over known processes involving the burning of the heavier grades of petroleum fuel oils such as those designated No. and No. 6 fuel oils and high solids content black liquor.
  • black liquor is the spent cooking liquor from the digesters plus the filtrate from the Washing operation. It is concentrated first in a multiple effect evaporator, next in a cascade or cyclone evaporator (a direct heat transfer device), then further concentrated by adding thereto a salt cake makeup and collected dust from the flue gas and hoppers, and finally heated prior to firing in the furnace. Inorganic components (sodium salts) in the concentrated black liquor are recovered in this burning operation as molten ash or smelt for reuse in the cooking liquor. Since all of these operations are well known in the art, a discussion thereof will not be repeated here.
  • Suitable N,N-dirnethylamides of straight chain carboxylic acids are those prepared from carboxylic acids containing 18 carbon atoms. The acids are further characterized by having at least one carbon to carbon double bond. Specific acids classified within this category include: oleic, linoleic, linolenic, ricinoleic, and mixtures thereof.
  • the N,N-dimethylamides of the foregoing acids are identified as N,N-dirnethyloleamide, N,N-dimethyllinoleamide, N,N-dimethyllinolenamide, and N,N-dimethylncinoleamide, respectively.
  • these amides may be added to the cyclone, to the venturi scrubber, or preferably to the salt cake mixer.
  • suitable quantities vary from about 10 to about 500 parts per million parts of black liquor or fuel oil.
  • the amount used varies from about to 100 parts per million parts of black liquor or fuel oil.
  • EXAMPLE 1 In this example the effectiveness of dimethylamide as an aid in processes involving the burning of high solids black liquor was determined by comparing the results of a series of runs in the presence of dimethylamide to a similar series of runs in the absence of that compound.
  • Example 2 Relative viscosity, Decrease in parts per million ccntipoises viscosity, percent EXAMPLE 2
  • the experimental procedures summarized in Example 1 were repeated in which the N,N-dimethylamides of the mixed acids found in castor, corn, cottonseed, linseed, olive, peanut, and soybean oils were used instead of the N,N-dimethylamides of tall oil fatty acids.
  • the results were similar to those obtained in Example 1.
  • a process of burning a viscous liquid fuel selected from the group consisting of petroleum fuel oil and black liquor comprising:
  • straight chain carboxylic acid is a mixture of straight chain carboxylic acids containing 18 carbon atoms and at least one carbon to carbon double bond.
  • N,N-dimethylamide is N,N-dimethyllinoleamide.
  • N,N-dimethy1 amide is N,N-dimethyllinolenamide.
  • N,N-dimethy1- amide is N,N-dimethylricinoleamide.
