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.

The invention relates to a method of recovering oil from a heterogeneous reservoir, comprising a plurality of permeable porous blocks of rock whose pores contain oil and which form interfaces with regions between the blocks, e.g. fractures, having a higher permeability than the blocks. The method comprises the steps of treating the interfaces such that the wettability of the surfaces of the blocks is in a predetermined wettability range, then reducing the permeability in the highly permeable regions, and finally flooding the reservoir by injecting a chase fluid into the reservoir. With the inventive method water phase bridges are established between adjacent blocks in the reservoir thus allowing a transmission of injection pressure for viscous displacement from one block to the next across the reservoir. The invention also relates to a method for long-time storage of CO 2 by using CO 2 as chase fluid or foaming gas according to the inventive method for oil recovery from heterogeneous reservoirs.

Cryogenic system for removing acid gases from a hydrocarbon gas stream, with removal of hydrogen sulfide

Номер: US20120204599A1
Автор: Bruce T. Kelley, Charles J. Mart, Paul Scott Northrop
Принадлежит: Individual

A system for removing acid gases from a raw gas stream includes an acid gas removal system (AGRS) and a sulfurous components removal system (SCRS). The acid gas removal system receives a sour gas stream and separates it into an overhead gas stream comprised primarily of methane, and a bottom acid gas stream comprised primarily of carbon dioxide. The sulfurous components removal system is placed either upstream or downstream of the acid gas removal system. The SCRS receives a gas stream and generally separates the gas stream into a first fluid stream comprising hydrogen sulfide, and a second fluid stream comprising carbon dioxide. Where the SCRS is upstream of the AGRS, the second fluid stream also includes primarily methane. Where the SCRS is downstream of the AGRS, the second fluid stream is principally carbon dioxide. Various types of sulfurous components removal systems may be utilized.

Dispersed Bubble Reactor For Enhanced Gas-Liquid-Solids Contact And Mass Transfer

Номер: US20120216680A1
Автор: Alexander Bonsu, Guohai Liu, Pannalal Vimalchand, Wanwang Peng
Принадлежит: Southern Co

An apparatus to promote gas-liquid contact and facilitate enhanced mass transfer. The dispersed bubble reactor (DBR) operates in the dispersed bubble flow regime to selectively absorb gas phase constituents into the liquid phase. The dispersion is achieved by shearing the large inlet gas bubbles into fine bubbles with circulating liquid and additional pumped liquid solvent when necessary. The DBR is capable of handling precipitates that may form during absorption or fine catalysts that may be necessary to promote liquid phase reactions. The DBR can be configured with multistage counter current flow sections by inserting concentric cylindrical sections into the riser to facilitate annular flow. While the DBR can absorb CO 2 in liquid solvents that may lead to precipitates at high loadings, it is equally capable of handling many different types of chemical processes involving solids (precipitates/catalysts) along with gas and liquid phases.

A gas separation process uses a structured particulate bed of adsorbent coated shapes/particles laid down in the bed in an ordered manner to simulate a monolith by providing longitudinally extensive gas passages by which the gas mixture to be separated can access the adsorbent material along the length of the particles. The particles can be laid down either directly in the bed or in locally structured packages/bundles which themselves are similarly oriented such that the bed particles behave similarly to a monolith but without at least some disadvantages. The adsorbent particles can be formed with a solid, non-porous core with the adsorbent formed as a thin, adherent coating on the exposed exterior surface. Particles may be formed as cylinders/hollow shapes to provide ready access to the adsorbent. The separation may be operated as a kinetic or equilibrium controlled process.

Method and device for treating a carbon-dioxide-containing gas flow, wherein the energy of the vent gas (work and cold due to expansion) is used

Номер: US20120240619A1
Автор: Annett Kutzschbach, Roland Ritter
Принадлежит: Linde KCA Dresden GmbH

The invention relates to a method and a device for treating a carbon-dioxide-containing gas stream, in particular from a large-scale fired plant, e.g. from a power plant. The precompressed gas stream is separated in a carbon dioxide purification stage into a gas substream having an elevated carbon dioxide content (carbon dioxide product stream) and a gas substream having a decreased carbon dioxide content (vent gas stream). The carbon dioxide product stream is fed to further utilization and/or storage. In particular, by injecting the carbon dioxide underground, the emission of gases harmful to the climate can be reduced. For improving the energy efficiency, it is proposed that the vent gas stream is expanded in at least one expansion turbine and both the resultant kinetic energy and the resultant refrigeration are utilized for energy recovery. For utilizing the kinetic energy, the expansion turbine can be coupled to a compressor (booster) which compresses the crude gas stream and/or the carbon dioxide product stream. For utilizing the refrigeration generated in the expansion, the at least partially expanded vent gas stream can be brought into heat exchange with process streams which are to be cooled, e.g. the crude gas stream and/or the carbon dioxide product stream.

In a method for adsorptively drying purified biogas and regenerating laden absorbents, foreign matter is not allowed to enter the purified biogas, the content of methane in the gas remains virtually unchanged and the effort involved in regenerating the laden adsorbent is reduced. Drying and regeneration are effected in a closed biogas cycle, wherein separate layers based on silica gel and molecular sieves are used as the adsorbent. The biogas to be dried first flows through the silica gel layer. The adsorbent is regenerated with exclusively heated, dried biomethane having a temperature of up to 150° C. which, after contact with adsorbent, is recirculated to the outflow of purified biogas. After regeneration, the bed is cooled by biomethane, which is subsequently recirculated to the outflow of purified biogas. Methane-containing water accumulating during drying and regeneration is recirculated to the biogas generation and/or purification.
