Patent number: 5112588Abstract: Gaseous contaminants, especially sulfur dioxide, sulfur trioxide, hydrogen chloride or hydrogen fluoride are removed from flue gases by chemisorption. A solid finely divided sorbent, before being brought into contact with the flue gas, is treated in a reactor with dry steam. The sorbent before introduction into the reactor is brought to a temperature of 10.degree. to 50.degree. C. below the dewpoint temperature of the steam in the reactor and the steam injected into the reactor is introduced at a temperature not more than 60.degree. C. above the dewpoint temperature, preferably 10.degree. to 40.degree. C. above the dewpoint temperature.Type: GrantFiled: July 24, 1990Date of Patent: May 12, 1992Inventors: Gernot Staudinger, Gernot Krammer

Patent number: 4590049Abstract: A method for desulfurizing exhaust gases such as flue gases from steam generators that have been charged with brown coal, in which powdered lime is charged into the furnace and then removed or precipitated from the flowing exhaust gases after a certain reaction time. The dust or particulate matter which has been removed from the flowing exhaust gas stream, and which is at least partially charged with noxious substances along the surfaces thereof, is pulverized and then subjected to dry stream hydration, followed by recycling into the flue gas stream which has been cooled to a lower temperature. During the dry steam treatment, the points of fracture or exposure of the pulverized particulate additive are activated so that Ca(OH).sub.2 formation takes place, which has a high affinity for sulfur dioxide at low temperature. An apparatus for pulverizing and hydrating the particulate matter is also provided.Type: GrantFiled: August 14, 1984Date of Patent: May 20, 1986Inventor: Gernot Staudinger

Patent number: 4519995Abstract: In a method for desulfurizing flue gas generated in coal combusting plants, the coal is burned in the presence of a dry additive material, such as CaCO optionally in presence of recycled cold flue gas whereby additive material which has not reacted is discharged together with the flue gas from the firing space and is separated together with the ashes in dust filters. The relative moisture of the flue gas is increased before entering the dust filter so that the sulfur compounds in the flue gas react to a greater extent with the additive material in the dust filters. The device for practicing this method comprises a heat exchanger and/or an injection cooler arranged streamup of the flue gas filtering installation.Type: GrantFiled: July 11, 1983Date of Patent: May 28, 1985Assignee: Osterreichische Draukraftwerke AktiengesellschaftInventors: Herbert Schrofelbauer, Gernot Staudinger

Patent number: 4509436Abstract: Flue gas from a coal-fired combustion to which a dry sulfur-binding additive is supplied, after cooling is subjected to filtration to remove additive ash therefrom. According to the invention, cooled additive ash is fed to at least a portion of the flue gas to reduce the temperature thereof approximately to the water dewpoint, thereby promoting the sulfur-binding reaction.Type: GrantFiled: September 30, 1983Date of Patent: April 9, 1985Assignee: Osterreichische Draukraftwerke AktiengesellschaftInventors: Herbert Schrofelbauer, Josef Kakl, Gernot Staudinger, Hermann Filipot

Patent number: 4323366Abstract: A pressure container forms a shaft gasifier for receiving coarse coal in the form of a coal bed. A burner extends through the pressure container into a chamber therein and produces at least one primary gas jet directed against the coal bed, thereby gasifying the coal and generating a product gas and forming liquid slag. The liquid slag collects in a slag bath tank having an overflow weir over which the collected slag flows and falls freely toward a cooling water bath beneath the chamber. A water jet nozzle directs at least one water jet against the liquid slag as it falls freely between the weir and the cooling water bath. This atomizes the liquid slag, thereby cooling the slag and generating steam. At least a part of the steam is supplied as process steam to the coarse coal.Type: GrantFiled: December 30, 1980Date of Patent: April 6, 1982Assignee: Voest-Alpine AGInventor: Gernot Staudinger

Patent number: 4054424Abstract: A process is disclosed for quenching of the partial combustion product gas of a slagging coal gasifier containing suspended molten slag particles wherein the hot product gas of the gasifier is passed through a tubular quench zone into which a shielding gas is introduced circumferentially to form an annular layer or protective gas shield between the product gas and the walls of the quench zone and a cooling gas is injected radially to effect direct cooling of the product gas to a temperature at which the molten slag particles solidify and lose their stickiness, said protective gas shield being maintained for a sufficient distance along the axis of the quench zone to prevent contact between the quench zone walls and the hot product gas during said cooling.Type: GrantFiled: June 5, 1975Date of Patent: October 18, 1977Assignee: Shell Internationale Research Maatschappij B.V.Inventors: Gernot Staudinger, Maarten J.

Patent number: 4049133Abstract: Dry coal powder is fed to a high-pressure coal gasification reactor from a high-pressure chamber in inert gas. The powder is introduced in the chamber via a centrifugal pump having an inlet tube passing through a wall of the chamber and a rotor inside the chamber, which rotor throws the powder into the chamber through radial nozzles by centrifugal force. Gas leakage from the chamber through the centrifugal pump is created to prevent blockage.Type: GrantFiled: April 14, 1976Date of Patent: September 20, 1977Assignee: Shell Internationale Research Maatschappij B.V.Inventor: Gernot Staudinger

Patent number: 3964882Abstract: A partial combustion process wherein a substantial portion of the soot formed in the combustion reactor is separated from the crude gas, e.g., by hot cyclones, and burned in a separate combustion zone with an excess of oxygen, optionally in the presence of steam, to yield a hot gas containing oxygen, carbon dioxide and water. This hot gas product, dependent on the ash content of the hydrocarbon feed is then subject to an optional solids removal step prior to its introduction into the partial combustion reactor where the oxygen contained therein supplies at least a portion of the oxidant requirement for partial oxidation and the carbon dioxide and water present therein are substantially converted to carbon monoxide and hydrogen.Type: GrantFiled: October 9, 1974Date of Patent: June 22, 1976Assignee: Shell Oil CompanyInventor: Gernot Staudinger
