  • Patent number: 4428866
    Abstract: A mixture of an alkyl amine, e.g., tri-n-propylamine and an SO.sub.3 -containing acid, preferably, sulfamic acid is injected into the flue gas stream of a coal-fired utility boiler to reduce the electrical resistivity of the fly-ash particles and to increase their mean particle size, thereby improving their recovery by electrostatic precipitation or by mechanical separation, with consequent reduction in stack emission.
    Type: Grant
    Filed: August 19, 1982
    Date of Patent: January 31, 1984
    Assignee: Dearborn Chemical Company
    Inventors: Richard L. Every, Franklin D. Lewandowski, Jerome F. Lech

  • Patent number: 4052503
    Abstract: Urea is produced by reacting phosgene and ammonia, one of the reactants being in the liquid state and the other gaseous, at -50.degree. to -20.degree. C.
    Type: Grant
    Filed: April 23, 1970
    Date of Patent: October 4, 1977

    Inventor: Richard L. Every
  • Patent number: 4043395
    Abstract: A process for removing methane from a subterranean coal deposit. A carbon dioxide-containing fluid is introduced into the coal deposit through an injection well and held therein for a period sufficient to enable a substantial amount of methane to be desorbed from the surfaces of the coal deposit. Following the hold period, the injected carbon dioxide-containing fluid and desorbed methane are recovered through a recovery well or wells spaced from the injection well. The process is repeated until sufficient methane has been removed to enable safe mining of the coal deposit.

  • Patent number: 3994531
    Abstract: The present invention relates to an improved method of solution mining potassium chloride from subterranean ore deposits containing both potassium chloride and sodium chloride. By the present invention, an aqueous medium is passed through the ore deposits so that potassium chloride and sodium chloride are dissolved therein. Magnesium chloride is combined with the aqueous brine solution formed so that an aqueous brine solution containing potassium chloride, sodium chloride and magnesium chloride in specific proportions is produced, and the solubility of potassium chloride in the solution is reduced. The combined aqueous brine solution is then concentrated so that it is substantially saturated with potassium chloride, and the concentrated solution is cooled to cause the precipitation of substantially pure potassium chloride.

  • Patent number: 3967860
    Abstract: The present invention relates to an improved method of transporting a sulfur-hydrocarbon slurry in a pipeline with a minimum of sulfur precipitation and adherence to the internal parts of the pipeline system. The improvement comprises maintaining the flow rate of the slurry to at least about the value given by the equationflow rate (feet per second) = 0.16 [.DELTA.T(.degree.F)-5]when the flow rate is below 8.0 feet per second, to thereby prevent the plating of sulfur on the walls of the pipeline by the precipitation of the dissolved sulfur in the sulfur-hydrocarbon slurry.
