Process For Producing Hydrogen Fluoride And Phosphoric Acid
US Patent:
4292289, Sep 29, 1981
Filed:
Feb 14, 1980
Appl. No.:
6/121486
Inventors:
Curtis W. Cannon - San Diego CA
Robert N. Hall - Boulder CO
Robert N. Hall - Boulder CO
Assignee:
Climax Chemical Company - Hobbs NM
International Classification:
C01B 2510, C01B 2516
US Classification:
423301
Abstract:
An improved method for producing hydrogen fluoride from fluoride bearing ores, such as fluorospar and fluorapatite, by reaction of the ore as a slurry in fluorosulfonic acid. The slurry is heated by the exothermic heat of the reaction to vaporize volatile phosphorous compounds and substantial quantities of hydrogen fluoride. The calcium fluoride is substantially reacted to form hydrogen fluoride. High silica fluorospar ores can be used since silicon tetrafluoride is not formed with fluorosulfonic acid. Another feature provides for addition of calcium fluoride to the slurry to react with the by-product sulfuric acid in the residual solids to eliminate the sulfuric acid recovery step in the process. Hydrogen fluoride produced is recovered, together with the hydrogen fluoride produced from the hydrolysis or pyrolysis of the intermediate fluorophosphorous compounds. Additionally, at least a portion of the hydrogen fluoride can be reacted with sulfur trioxide to form fluorosulfonic acid for makeup in the process.
Process For Manufacture Of Phosphoric Acid And Phosphorus Pentafluoride
US Patent:
4202867, May 13, 1980
Filed:
Jan 4, 1979
Appl. No.:
6/000987
Inventors:
Curtis W. Cannon - San Diego CA
Robert N. Hall - Boulder CO
Robert N. Hall - Boulder CO
Assignee:
Climax Chemical Corporation - Hobbs NM
International Classification:
C01B 2510, C01B 2516
US Classification:
423301
Abstract:
An improved method for treating calcium phosphate sources such as bone phosphate and phosphate rock with fluorosulfonic acid in the presence of a limited amount of moisture whereby over 98. 00% of the phosphorous is converted to volatile compounds that can be subsequently hydrolyzed. A substantial excess of fluorosulfonic acid is utilized to contact the phosphate ore as a slurry. The phosphorous products are primarily phosphorous pentafluoride and phosphorous oxyfluoride, and to a limited extent difluorophosphoric acid. A trace of water apparently catalyzes the reaction. The production of phosphorous pentafluoride is favored by up to one part of water to eight parts of ore by weight in the presence of excesses of fluorosulfonic acid. The method includes the hydrolysis of the volatile compounds to phosphoric acid and hydrogen fluoride. Hydrogen fluoride is then recycled to react with the required sulfur trioxide to make the requirement of fluorosulfonic acid for the process.
Process For Recovering Carbonaceous Liquids From Solid Carbonaceous Particles
US Patent:
4421603, Dec 20, 1983
Filed:
Feb 26, 1982
Appl. No.:
6/352653
Inventors:
Robert N. Hall - Boulder CO
Assignee:
Tosco Corporation - Los Angeles CA
International Classification:
C10B 4922, C10B 5306, C10B 5702
US Classification:
201 12
Abstract:
Pyrolysis process and system for recovering product gases and liquids from solid carbonaceous particles.
Dual stage fluidized bed retort is disclosed having frusto-conical stages serially connected to promote uniform pyrolysis. Product gases and oil are removed from final fluid bed stage in series. Process includes various energy efficient aspects involving recycle of dilute phase combusted solids as the heat carrier, heavy oil recycle and use of steam and/or product vapors as the source of fluidizing gas for the staged retort.
Circulating Bed Heat Exchanger For Cooling Shale Ash
US Patent:
4509589, Apr 9, 1985
Filed:
Aug 5, 1982
Appl. No.:
6/405529
Inventors:
Franklin B. Carlson - Broomfield CO
Robert N. Hall - Boulder CO
Robert N. Hall - Boulder CO
Assignee:
Tosco Corporation - Santa Monica CA
International Classification:
F28G 1300
US Classification:
165 95
Abstract:
A process and system for simultaneously cooling shale ash fines and flue gas produced during the combustion of spent shale. The flue gas and fine solids are introduced into a heat exchange zone for contact with conventional heat exchange tubes. Heat transfer particles are introduced into the heat exchange zone for mixing with the flue gas to provide increased heat transfer rates between the flue gas and heat exchange equipment. The heat transfer solids are also of a sufficient size to provide continual scrubbing of the heat exchanger surfaces to prevent the build up of an insulating layer of fine dust particles. A staged cooling system and process is also disclosed.
Process For Combusting Carbonaceous Solids Containing Nitrogen
US Patent:
4413573, Nov 8, 1983
Filed:
Jun 21, 1982
Appl. No.:

Assignee:
Tosco Corporation - Los Angeles CA
International Classification:
F03D 100
US Classification:
110347
Abstract:
A dual stage combustion system and process for achieving high fuel combustion efficiency and reduced nitric oxide emissions. Combustion is carried out in two stages. A first partial combustion carried out in an oxygen deficient atmosphere followed by a second complete carbon combustion in an oxidizing atmosphere. The second combustion step achieves complete fuel utilization, but generates a nitrogen oxide containing flue gas. The nitrogen oxide containing flue gas is passed to the first combustion step where it is removed by interaction with the partially combusted solids.
