Method and Apparatus for Controlling Acid Gas Emissions from Cement Plants

Номер: US20120039778A1
Автор: James J. Schwab
Принадлежит: Envirocare International Inc

A method and apparatus for controlling emissions of acid forming gases such as sulfur dioxide from cement plants is disclosed. Gaseous effluent from the cement plant pyroprocessing chamber is routed to the plant's raw mill to heat and dry the feed meal used in cement production. When the raw mill is in operation microfine lime particles are sprayed into the raw mill using a nozzle system. The spraying of hydrated lime into the raw mill scrubs acid forming gases in the process gaseous effluent. When the raw mill is not operational, microfine lime is sprayed into a gas conditioning tower that is also used to reduce the temperature of the effluent gases to facilitate efficient collection of dust particles prior to emission of the cleansed effluent flow into the atmosphere.

One exemplary embodiment can be a process for purifying a natural gas by using first and second adsorbers. The process may include passing a feed including the natural gas through the first adsorber to obtain a purified natural gas product, regenerating the second adsorber in a heating stage, and regenerating the second adsorber in a cooling stage. The heating stage may include separating a portion of the feed comprised in a regeneration gas, passing the regeneration gas to a dryer for removing water, heating the regeneration gas with a heater after exiting the dryer, and passing the regeneration gas to the second adsorber to regenerate the second adsorber. The cooling stage may include expelling at initiation of cooling at least a part of a fluid present in the second adsorber to the dryer to desorb water from a molecular sieve in the dryer, and cooling the second adsorber by circulating the regeneration gas bypassing the heater.

Vapor recovery system utilizing compression-condensation processes and related methods

Номер: US20120042691A1
Автор: Carol Diane Krumbholz
Принадлежит: Individual

An off gas extraction system cleans common sources of off gas, such as storage tanks and polluted soils. Off gas is extracted, followed by compression and condensation. Compression and condensation produce an off gas that can be reintroduced as a treated gas into the off gas source. Alternatively, a regenerative absorber cleans the treated gas by adsorbing residual chemical vapor and concentrates the removed chemical vapors and reprocesses them. If the treated gas is not reintroduced into the off gas source, conventional scrubbers may used on the back end of the system to produce a final exhaust as prescribed by environmental regulation. Methods of accomplishing the same are similarly provided, including novel methods for degassing storage tanks and treating polluted soils to meet current environmental regulations, as well as green technology and sustainability initiatives.

The disclosure provides for oxygen separation from air by utilizing an initial oxygen carrier which undergoes an endothermic reduction reaction to produce a carrier product and gaseous oxygen. The gaseous oxygen is withdrawn, and the carrier product is subsequently further reduced with a fuel in a combustion process, releasing heat and generating a oxygen acceptor. The oxygen acceptor is oxidized in an exothermic reaction. The method thus couples the exothermic oxidation reaction, the endothermic reduction reaction, and the chemical energy supplied by the fuel for a net heat release. In an embodiment, the initial oxygen carrier is CuO, the carrier product is Cu 2 O, and the oxygen acceptor is Cu.

An apparatus and a system is provided that may be utilized to determine air flow through an air filter and/or a plurality of air filters. The present invention utilizes a demonstration apparatus to illustrate the differences in air flow and air restriction between a plurality of different air filters and filtration media. The apparatus and system utilizes a common plenum which subjects the plurality of air filters to the same differential pressure. The air flows through a first side of the air filter and is measured on the second side of the air filter by utilizing a wind meter or similar device to gauge the amount of air flow velocity of the second side of the filter. Additionally, the apparatus and system utilizes a display means to illustrate the differing air velocity through the second side of the air filter.

The invention relates to a method as well as a device for separation of a carbon-dioxide-containing gas mixture ( 1 ), whereby carbon dioxide is separated from the carbon-dioxide-containing gas mixture ( 1 ) by physical gas washing (W 1 ) and is converted into two product streams ( 3, 4 ) that consist primarily of carbon dioxide and have different pressures, and in the event of an operational breakdown, after their pressures are balanced, said product streams are subjected to an after-treatment step (W 2 ) and then are released into the atmosphere. For balancing the pressures of the two carbon dioxide product streams ( 3, 4 ), the carbon dioxide stream ( 3, 7 ) that has the lower pressure is compressed by means of a gas jet ventilator (G), whereby the carbon dioxide stream ( 4 ) that has the higher pressure is used as a pumping medium ( 6 ).

Принадлежит: Individual

A process for separating a mixture of gases into a relatively condensable first component and a relatively non-condensable second component is provided. The first component comprises one or more gases selected from the group consisting of carbon dioxide, carbonyl sulphide and hydrogen sulphide and the second component one or more gases selected from the group consisting of hydrogen, methane, ethane, carbon monoxide, nitrogen, oxygen and synthesis gas. The process itself comprises the following steps: (a) compressing and cooling a mixture of said first and second components in at least one compressor and at least one heat exchanger to a temperature and elevated pressure at which the first components condense and a two-phase gas-liquid mixture is formed; (b) separating the two phase mixture so formed into separate liquid first and gaseous second component fractions in a fractionation unit; (c) extracting residual first component from the separated gaseous second component fraction by scrubbing the second component at elevated pressure with a solvent (e.g. methanol) in a scrubber. In examples, the method further includes one or more steps of warming and expanding the gaseous second component fraction using at least one heat exchanger to exchange heat with a process stream and at least one turbo-expander capable of recovering mechanical work. The process described is highly energy efficient and is especially useful in hydrogen power plants, Integrated Gasification Combined Cycles (IGCC) and for sweetening sour natural gas.

The filter patches impede passage of wear particles of a size larger than their pore size therethrough, thereby separating the wear particles according to the sizes of the wear particles. The tube is attached to a handler of a centrifuge for centrifugation by the centrifuge. Multiple tubes can be attached to multiple handlers of the centrifuge for simultaneous centrifugation by the centrifuge. Centrifugation tubes (or tubes) are also provided by the present disclosure.

Attrition resistant hardened zeolite materials for air filtration media

Номер: US20120118160A1
Автор: Fitzgerald A. Sinclair, Michael C. Withiam, Ruth G. Heffes, Terry W. Nassivera
Принадлежит: JM Huber Corp

Environmental control in air handling systems that are required to provide highly effective filtration of noxious gases particularly within filter canisters that are ultrasonically welded enclosures is provided. In one embodiment, a filtration system utilizes a novel zeolite material that has been hardened to withstand ultrasonic welding conditions in order to reduce the propensity of such a material to destabilize and/or dust. Such a hardened zeolite thus enables for trapping and removal of certain undesirable gases (such as ammonia, ethylene oxide, formaldehyde, and nitrous oxide, as examples) from an enclosed environment, particularly in combination with metal-doped silica gel materials. Such a hardened zeolite is acidic in nature and not reacted with any salts or like substances and, as it remains in a hardened state upon inclusion within a welded filter device, the filter medium itself permits proper throughput with little to no dusting, thereby providing proper utilization and reliability for such a gas removal purpose. Methods of using and the application within specific filter apparatuses are also encompassed within this invention.
