    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.

    Abstract: Germanium radiation detectors are manufactured by diffusing lithium into high purity p-type germanium. The diffusion is most readily accomplished from a lithium-lead-bismuth alloy at approximately 430.degree. and is monitored by a quartz half cell containing a standard composition of this alloy.Detectors having n-type cores may be constructed by converting high purity p-type germanium to n-type by a lithium diffusion and subsequently diffusing some of the lithium back out through the surface to create a deep p-n junction.Coaxial germanium detectors comprising deep p-n junctions are produced by the lithium diffusion process.

    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.

    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.

    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. Fluorosulfonic acid not consumed in the process is recovered for reuse in the process. Dependent on the form of silica impurities in the ore, a net production of hydrogen fluoride may be obtained from the fluoride content of the rock. The process is relatively self-sustaining as far as hydrogen fluoride used for making fluorosulfonic acid requirements is concerned. Sulfur trioxide is essentially the net reagent required to treat the ore to produce the volatile phosphorous intermediates for subsequent conversion to phosphoric acid and hydrogen fluoride.
