Scrubbing fluid and methods for using same

A scrubbing solution for removing contaminants, including particularly hydrogen sulfide, from a fluid. The scrubbing solution includes at least one scrubbing reagent which has a primary or secondary amine and an acid, which may be phosphoric acid. The fluid being scrubbed is passed through the scrubbing solution. The contaminants react with the scrubbing reagent securing them in the scrubbing solution. The fluid being scrubbed and the scrubbing solution are then separated. The scrubbing solution is heated and, if the scrubbing solution is under pressure, the pressure is reduced. The acid facilitates thorough removal of the contaminants, and especially the hydrogen sulfide, from the scrubbing solution. The scrubbing solution is then ready for reuse. Because the scrubbing solution is rendered substantially free of hydrogen sulfides, it can absorb other sulfide contaminants that might not otherwise be absorbed.

Delivery mechanisms and distribution mechanisms are varied, adjusted, or modified based on a desired fuel application. Dimensions, flow rates, pressures, viscosities, temperatures, friction parameters, and combinations thereof may be varied, adjusted or modified. The fuel application may include a scrubber application. The scrubber application uses a delivery mechanism to deliver a wet or dry scrubbing agent at a low pressure to a distribution mechanism. The distribution mechanism distributes the scrubbing agent within the scrubbing chamber. The delivery mechanism is adjustable based on properties of a feedstock utilized to deliver the scrubbing agent, properties of a propellant, or properties of the scrubbing application. The distribution mechanism is adjustable based on desired distribution characteristics including shape, size, or velocity of drops, mists, or particles distributed. Location, processes, and by-products associated with output of the scrubbing application may be based on a stage of the scrubbing application.

Methods of decontaminating bone tissue and an apparatus or system for the same are provided. The methods can be multi-batch processes and include contacting the bone tissue having contaminants with carbon dioxide to decontaminate the bone tissue and to form carbon dioxide having contaminants. The contaminated carbon dioxide is collected and the contaminants are removed to obtain purified carbon dioxide which can be recycled to treat contaminated bone tissue. The contaminated carbon dioxide can be purified by bubbling it through water and/or an organic solvent followed by acid treatment, filtering and liquefying the carbon dioxide. Contaminants that can be removed from contaminated bone tissue, and in turn, from contaminated carbon dioxide include infectious organisms, bacteria, viruses, protozoa, parasites, fungi and mold or a mixture thereof

Production and isolation of monocyclic aromatic compounds from a gasification gas

The present invention concerns a process and system for producing and isolating a fraction of monocyclic aromatic compounds from a gasification gas. The process comprises (a) contacting the gas with a catalyst capable of converting ethylene and possibly other unsaturated hydrocarbons into monocyclic aromatic compounds; and (b) isolating monocyclic aromatic compounds from the gas originating from step (a). The present invention is ideally suited for treatment of gas from coal, biomass or waste gasification, which comprises substantial amounts of ethylene as well as monocyclic aromatic compounds. Treatment according to the invention first converts the ethylene into further monocyclic aromatic compounds, and the entire fraction of monocyclic aromatic compounds is isolated to obtain a valuable product.

Method of producing sulfur-depleted syngas

A system and method for processing unconditioned syngas first removes solids and semi-volatile organic compounds (SVOC), then removes volatile organic compounds (VOC), and then removes at least one sulfur containing compound from the syngas. Additional processing may be performed depending on such factors as the source of syngas being processed, the products, byproducts and intermediate products desired to be formed, captured or recycled and environmental considerations.

Process and plant for removing thiols from synthesis gas

The invention relates to a process and a plant for removing thiols from synthesis gas. Thiols and optionally thiophene and carbon disulfide are absorbed in a dedicated absorption stage with methanol as physical absorption medium. Methanol laden with at least thiols is freed of thiols in a stripping stage with methanol vapours as stripping gas and the methanol vapours-containing thiols are freed of methanol in a scrubbing stage. The process according to the invention minimizes methanol losses and the amounts of coolant required for the process.

An Air-Water-Food-Fabric-Space-Utility sanitizer (all in one) comprises a detachable blower chamber, a detachable UVC lamp holder, a detachable UVC lamp chamber, a detachable water chamber and a detachable lid. Said invention transforms to an air purifier, a chamber-style sanitizer, or a stand-style sanitizer when one or more chambers are detached. Germicidal lamps surround a target such as air, water, food (meats, plants), fabric (masks, towels), space, utility and soil to kill pests, parasites, insects and pathogenic spores. Said invention also develops seed germination. Water converts gas (MVOC) to liquid and arrests airborne contaminants. A blower drives them to water to enable the use of optimal dosage of UVC light. By either UVC-irradiating water or oxidizing water, pathogens are destroyed in the water chamber. Filters activate spore dispersal when disposed by burning. By not using potentially hazardous waste or an air outlet, pathogenic spores cannot reproduce or return to the environment.
