Patent Number Title Of Patent Date Issued
4931012 Phase contactor/process for generating high temperature gaseous phase June 5, 1990
A phase contactor adopted, e.g., for combustion and pollution control, comprises a mixing zone and means for separately injecting and disintegrating at least two gaseous flowstreams therein, a central element within said mixing zone defining an annular space into which said gaseous f
4910008 Gas-gas phase contactor March 20, 1990
A gas-gas phase contactor/process, especially adopted for high temperature reactions, e.g., for the production of hydrochloric acid, comprises means for separately establishing at least two disparate gaseous feedstreams, means for disintegrating each such feedstream into a registered plu
4832822 Steam cracking of hydrocarbons May 23, 1989
The steam and thermal cracking of hydrocarbons is facilely carried out by in situ generating a stream of hot combustion gases including steam, advantageously in the configuration of a downstream axially extending, axially symmetrical helical flowstream, by combustion of steam-producing
4758249 Hydrogen reduction of carbonaceous source to form carbon monoxide July 19, 1988
Carbon dioxide is facilely converted into carbon monoxide and water, and advantageously into a syngas, by establishing a thermally homogeneous gaseous admixture including carbon dioxide and hydrogen having a temperature of at least 800.degree. C., within a period of time essentially
4595579 Process for initiating a reaction for the manufacture of synthetic hydrochloric acid June 17, 1986
The invention relates to a process for initiating a reaction for the manufacture of synthetic hydrochloric acid, wherein two reactive gaseous chamical compounds, chlorine and hydrogen, are brought together. The molecules of at least one of said compounds are then excited by projection
4562778 High temperature reaction apparatus January 7, 1986
A high temperature reactor includes a reaction chamber which is symmetrical about a longitudinal axis. Surrounding the reaction chamber are annular spaces to which a gaseous reactant is supplied. A plurality of conduits conduct the gaseous reactant from the annular spaces to the reaction
4526529 Clean combustion process/apparatus July 2, 1985
The clean combustion of a combustible material is facilely carried out by (i) in situ generating a dispersing first stream of hot combustion gases by establishing a first downstream axially extending, axially symmetrical helical flowstream of combustion-supporting gases in a first combus
4505667 Device which can be used for the combustion of corrosive products and process using this device March 19, 1985
The invention relates to a method and device for the combustion of corrosive products, such as chlorine containing residues, comprising a combustion chamber, a dispersing head having an axial inlet for the phase to be burnt, and means for introducing two separate fractions of the com
4447331 Intimate contacting/separating of plural phases May 8, 1984
Intimate contacting of plural, physically disparate phases, e.g., for the purification of waste waters typically comprising sulfide and polysulfide pollutants, is effected by (i) co-atomizing a first liquid stream which comprises solid waste progenitors together with a second fluid strea
4350101 Device for treating substances in different phases, such as the treatment of substances in liqui September 21, 1982
A device and process for the treatment of materials in different phases, one material being in a fluid phase and another in a gaseous phase, wherein the material in fluid phase is introduced as a stream within the axis of the gaseous phase in helicoidal flow for subsequent passage th
4267131 Method for intimate contacting of plural phases and phase contactor apparatus therefor May 12, 1981
Intimate contacting of plural, physically disparate phases is achieved by establishing a current of axially extending, axially symmetrical helical flow of a first phase; separately establishing a current of coaxially extending, rectilinear flow of a physically disparate second phase, the
4265702 Method and apparatus for the treatment of heat-sensitive materials May 5, 1981
The drying and dehydration of heat-sensitive materials is improved by submitting such materials to a second thermal treatment following their initial flash treatment. The method is particularly applicable to the treatment of foodstuffs.
4263234 Method of intimate contacting/separating of plural phases and phase contactor/separator apparatu April 21, 1981
Intimate contacting of plural, physically disparate phases is achieved by establishing a current of axially extending, axially symmetrical helical flow of a first phase; separately establishing a current of coaxially extending, rectilinear flow of a physically disparate second phase, the
4257339 Process for treating substances in different phases, such as the treatment of substances in liqu March 24, 1981
Apparatus and process for treatment of materials in different phases, one of which is in a fluid phase and another of which is in a gaseous phase, wherein the material in fluid phase is introduced as a stream within the axis of the gaseous phase in helicoidal flow for subsequent passage
