Abstract: A method for improving flame resistance in filter systems in which an air flow charged with flammable aerosols is fed to a filter. The filter prevents a least a substantial portion of the flammable aerosol from reaching the air flow exiting the filter. A granular flame retardant material is fed to the air flow containing the flammable aerosols prior to the air flow containing the flammable aerosols being fed to the filter. The flame retardant has porous mineral granuales as an essential component.

Abstract: A filter assembly is adapted for separating particulate matter entrained in a moving fluid stream. The filter assembly comprises a flow-through three dimensional filter frame including a plurality of joined side walls, and having first and second opposing open faces. The first open face defines a fluid inlet into which the moving fluid stream is drawn, and the second open face defines a fluid outlet from which the moving fluid stream passes. At least one of the joined side walls is inwardly angled from the first open face to the second open face, such that the fluid outlet is smaller than the fluid inlet. A filtration medium is supported within the filter frame, and extends between the joined side walls and from the first open face to the second open face.

Abstract: A filter apparatus is equipped with a first body, a case unit connected to a lower part of the first body, and a filter unit, which is accommodated in the interior of the case unit. The case unit is made up from an outer case, which is formed as a bottomed cylinder from a light-permeable transparent material, and an inner case that is inserted into the interior of the outer case. The case unit is inserted into an installation hole that opens on the lower part of the first body, and by rotation thereof, projections and retaining walls provided on an outer circumferential surface of the case unit are made to engage with support members provided in the installation hole, to thereby result in a connected state.

Abstract: In a reclaiming apparatus (106) that includes an airtight container (106a) as an absorbent storing unit that stores a part of an absorbent that absorbs CO2 included in an exhaust gas and a heating unit that heats the absorbent stored in the airtight container (106a), a part of the absorbent stored in the airtight container (106a) is distributed, and a gaseous body is brought into counterflow contact with the absorbent that is distributed. As a result, since the gaseous body is brought into counterflow contact with a part of the absorbent stored in the absorbent storing unit, an absorbent component volatilizes and is separated from a degraded material, and the absorbent component can be extracted from the degraded material, whereby a loss of the absorbent can be reduced.

Abstract: A system and process for extending turndown in a gas-liquid separator is presented. The system includes a first mist extractor with a first operating range and a second mist extractor with a second operating range. The mist extractors are generally of the same type, with the second operating range being different than the first operating range. A gas stream containing entrained liquid droplets flows through the first mist extractor and then through the second mist extractor. Each mist extractor coalesces and captures the liquid droplets within its own operating range, expanding the overall operating range of the separator. Additional mist extractors may be added to cover any gap between the first and second operating ranges.

Abstract: The invention relates to a column, with a jacket, extending along a longitudinal axis, which jacket bounds a first jacket space and a second jacket space arranged over it along the longitudinal axis, a chimney tray, extending crosswise to the longitudinal axis, that separates the two jacket spaces from one another. The at least a first chimney extends from the tray along the longitudinal axis, and projects into the second jacket space. The chimney has a peripheral wall defining an opening, via which the two jacket spaces are connected to one another for gas feed, and a chimney top. On the peripheral wall, a flat impact element is arranged tilted toward the longitudinal axis in such a way that a liquid phase flowing downward from the chimney top along the longitudinal axis strikes the flat impact element diminishing the momentum input of the liquid phase that stands on the chimney tray.

Abstract: A concentric split flow filter may be configured to remove odor and/or bacteria from pumped air used to collect urine and fecal waste products. For instance, filter may be designed to effectively fill the volume that was previously considered wasted surrounding the transport tube of a waste management system. The concentric split flow filter may be configured to split the air flow, with substantially half of the air flow to be treated traveling through a first bed of filter media and substantially the other half of the air flow to be treated traveling through the second bed of filter media. This split flow design reduces the air velocity by 50%. In this way, the pressure drop of filter may be reduced by as much as a factor of 4 as compare to the conventional design.
