Described are methods, devices, and systems useful for adsorbing organometallic vapor onto solid adsorbent material to remove the organometallic vapor from a gas mixture that contains the organometallic vapor and other vapor, particulate materials, or both.

An industrial air pollution removal system that eliminates unwanted gases from the environment includes a four-step process. The first step is an investigatory process to gather all the properties of the stack as flow rate, gas types, and hottest point of the stack. A second step captures either through water in the vat phase or sublimation of carbon dioxide and mercury into slabs of dry ice. In the byproducts, internal uses can be found to defray costs. A third step is the transportation of vat phase by truck and dry ice in refrigerated truck. A fourth step is the fractionalization center will recycle the captured emissions, such as separation of particulate matter, distillation for the liquid, sublimation of the dry ice and mercury, and using a dry ice processing plant. The goal is the sale of recycled materials as raw materials, conserve natural resources, and to positively affect climate change.

Described are methods, devices, and systems useful for removing gaseous ammonia from a gas mixture at a pressure in an ambient pressure range by allowing the ammonia to adsorb onto a solid adsorbent, as well as related systems and methods.

The invention relates to a process for removal of metal carbonyls from crude synthesis gas in a gas scrubbing process with a physical scrubbing medium. Scrubbing medium laden with hydrogen sulfide (H.sub.2S) and metal carbonyls is sent to a treatment vessel having a residence time region and a scrubbing region. Metal carbonyls are precipitated from the laden scrubbing medium as metal sulfides in the residence time region. The scrubbing region is supplied with a regenerated scrubbing medium. According to the invention it is provided that the residence time region and the scrubbing region are separated from one another by a gas-permeable tray, a regenerated scrubbing medium-comprising liquid layer adjacent to the gas-permeable tray is formed in the scrubbing region, metal carbonyls outgassing from the residence time region pass through the gas-permeable tray and are absorbed by regenerated scrubbing medium in the scrubbing region, wherein scrubbing medium comprising metal carbonyls is obtained and metal carbonyls outgassing from the residence time region are cooled by the liquid layer. The invention further relates to a treatment vessel, to the use of the process, treatment vessel or apparatus according to the invention in a gas scrubbing process with methanol as the physical scrubbing medium and to the use of the treatment vessel in a process according to the invention.

A method and apparatus for removing a volatile component from a mixture are disclosed. The method and apparatus employ a crosslinked elastomer with a glass transition temperature +25 C. as the sorbent.

Compositions that can be used to adsorb low concentration, of unwanted or target substances from a dynamic fluid stream or from an enclosed static vapor phase. Such adsorbency can be obtained with thermoplastic materials used in the form of bulk polymer or a film, fiber, web, woven fabric, non-woven fabric, sheet, packaging and other such structures including or surrounding the enclosed volume. The concentration should be reduced to non-offensive sensed limits or a limit that does not produce a biological response.

A fluid storage and dispensing apparatus including a fluid storage and dispensing vessel having a rectangular parallelepiped shape, and an integrated gas cabinet assembly including such fluid storage and dispensing apparatus and/or a point-of-use ventilation gas scrubber in the vented gas cabinet. By the use of physical adsorbent and chemical sorbent media, the gas cabinet can be enhanced in safety of operation, e.g., where the process gas supplied from the gas cabinet is of a toxic or otherwise hazardous character.
