The present invention relates to a device for absorbing water using a liquid desiccant and the regeneration of said liquid desiccant by evaporating the absorbed water. The device may further be used in an air cooler. The invention also relates to a method for controlling a device for absorbing water.

As an organic iodine remover that removes organic iodine in a containment vessel of a nuclear reactor, an organic agent (for example, an ionic liquid, an interfacial active agent, a quaternary salt, or a phase transfer catalyst) having a function of dissolving and decomposing the organic iodine and retaining iodine is used. The organic iodine remover is a substance composed of a cation and an anion. The organic iodine remover is, in particular, an organic iodine remover in which, in a structure of the cation of the organic agent, carbon or oxygen is bonded to, via a single bond, to a phosphorus element, a sulfur element or a nitrogen element, the number of carbon chains is 2 or more, and an anionic structure is configured with a substance with high nucleophilicity. By using such an organic agent, the organic iodine is removed with an efficiency of 99% or more.

The principal approaches to reducing the effects of global warming seek to slow the increase in atmospheric CO2 levels as a result of fossil fuel combustion for energy production and transportation. A process for hybrid carbon capture and mineralization are disclosed. The process utilizes both flue gas from (e.g., power plants) and reject brine from (e.g., desalination process). The process includes providing flue gas to react with an amine solution to produce carbamate; processing the carbamate in a reactor to regenerate amine and to produce a carbonate; treating reject brine to provide a ready-made brine for carbonation reaction; and processing the carbamate with salt from treating the brine to produce a carbonate.

The present invention relates to a method of capturing CO.sub.2 from a gas stream. The method uses a two liquid phase capture composition.

A scavenger comprising a formaldehyde sulfoxylate may be used to scavenge hydrogen sulfide (H.sub.2S) from systems that are brine or mixed production. Suitable formaldehyde sulfoxylates include, but are not necessarily limited to, sodium formaldehyde sulfoxylate, zinc formaldehyde sulfoxylate, and calcium formaldehyde sulfoxylate, potassium formaldehyde sulfoxylate, magnesium formaldehyde sulfoxylate, iron formaldehyde sulfoxylate, copper formaldehyde sulfoxylate, alkene aldehyde sulfoxylates, and combinations thereof.

A method for simultaneously removing high-load sulfur dioxide and nitrogen oxide in waste gas, relating to the technical field of industrial waste gas purification by biological methods. According to the method, the waste gas is led into a simultaneous desulfurization and denitrification packing tower and removed, microbial floras for simultaneously removing the sulfur dioxide and the nitrogen oxide are loaded on fillers of the packing tower, and the molar concentration ratio of the sulfur dioxide to the nitrogen oxide in the waste gas is (0.76˜1.06):1.

Steric effects on amine sites beta to amide or ester functional groups are utilized to result in a family of CO.sub.2 solvents with an unprecedented hybridization of chemisorption and physisorption properties. These versatile solvents provide very high CO.sub.2 working capacities in applications typically involved with physical solvents such as Selexol, Genosorb, Fluor Solvent, Purisol, and Rectisol with the added benefit of operation near ambient conditions without the need for solvent chilling along with the potential for high pressure recovery of CO.sub.2. The non-aqueous BAC solvents can also be tailored for low partial pressure CO.sub.2 removal as required in such applications as biogas/landfill gas upgrading and CO.sub.2 removal from industrial processes such as cement and steel manufacturing where they benefit from lower energy requirements for regeneration compared to tradition aqueous amine solution, regeneration under 1 bar CO.sub.2 without steam stripping, reduced corrosion potential, reduced solvent loss, reduced environmental impact, higher volumetric CO.sub.2 uptake compared to standard commercialized processes involving physical solvents, and operation at ambient pressure without the need for feed gas compression.
