The invention is directed to a treatment fluid comprising electrolyzed water and an amine, and methods for producing and using same in the treatment of a gas or liquid containing a contaminant such as an acid gas or a sulphur compound.

A system for processing a gas stream can include a physical solvent unit, an acid gas removal unit upstream or downstream of the physical solvent unit, and an LNG liquefaction unit downstream of the acid gas removal unit. The physical solvent unit is configured to receive a feed gas, remove at least a portion of any C.sub.5+ hydrocarbons in the feed gas stream using a physical solvent, and produce a cleaned gas stream comprising the feed gas stream with the portion of the C.sub.5+ hydrocarbons removed. The acid gas removal unit is configured to receive the cleaned gas stream, remove at least a portion of any acid gases present in the cleaned gas stream, and produce a treated gas stream. The LNG liquefaction unit is configured to receive the treated gas stream and liquefy at least a portion of the hydrocarbons in the treated gas stream.

Methods and systems for treating a liquid material. A liquid is emplaced in a treatment zone: microwave energy and ultrasonic energy are collectively applied to the treatment zone to effect release of a gaseous material from the liquid material.

Systems and methods for treating contaminated water as a source for hydrogen is disclosed herein. A hydrogen-gas-containing gaseous byproduct from treating contaminated water is collected, and gases other than hydrogen are removed therefrom to form a hydrogen-rich gaseous product. The hydrogen-rich gaseous product may then be used as fuel to power the contaminated water treatment step.

A method of desorbing CO.sub.2 from an aqueous liquid comprising CO.sub.2, the method comprising the steps of: a) providing said aqueous liquid in the form of an aqueous colloidal solution comprising (i) a CO.sub.2 absorbent having CO.sub.2 absorbed thereto and (ii) colloidal catalyst having a core-shell structure in which the shell comprises proton-donor groups, and b) thermally desorbing CO.sub.2 from the CO.sub.2 absorbent, wherein the thermal desorption of the CO.sub.2 is catalysed by the colloidal catalyst.

Disclosed herein is a gas capture system comprising: a first reactor system arranged so that, in the first reactor system, at least some gas in a gas stream that is received by the gas capture system is captured by a sorbent that is arranged to flow through the first reactor system; a second reactor system arranged to regenerate the sorbent so that the sorbent releases at least some of the gas captured in the first reactor system, wherein the sorbent is arranged to flow through the second reactor system and the second reactor system is arranged to output a gas flow that comprises the released gas; a first sorbent transfer system arranged between a sorbent outlet of the first reactor system and a sorbent inlet of the second reactor system; a second sorbent transfer system arranged between a sorbent outlet of the second reactor system and a sorbent inlet of the first reactor system; and a heat pump system comprising a heat pump arranged to circulate a flow of working fluid, wherein the heat pump system is arranged to extract heat from the first reactor system and/or the gas flow output from the second reactor system; wherein: the sorbent is a liquid; the second reactor system comprises a pump arranged to reduce the pressure in the second reactor system so that the pressure in the second reactor system when regenerating sorbent may be lower than the pressure in the first reactor system during gas capture by the sorbent; and the first reactor system, first sorbent transfer system, second reactor system and second sorbent transfer system are all arranged so that they provide a sorbent flow path that recirculates the sorbent between the first reactor system and the second reactor system.

The present invention relates to an absorbent having improved carbon dioxide capture performance of an amine solution to which a reaction accelerator is added and a method for manufacturing the same, specifically relates to an absorbent in which an amine solution is mixed with a primary amine containing an aromatic ring as an active additive that can improve the absorption rate to improve both the absorption performance and the absorption rate, and a method for manufacturing the same. According to an embodiment of the present invention, it is possible to provide an absorbent, which exhibits excellent CO.sub.2 capture performance and has a higher absorption rate, a higher absorption capacity, and lower heat of absorption than an absorbent used in the conventional CO.sub.2 capture process by combining a tertiary amine with a primary amine and DEEA used as a tertiary alkanol amine can be manufactured from agricultural products or residues, which are renewable resources, so the final absorbent can be manufactured at low cost, and the present invention can be usefully used as a technology that can reduce energy demand in the field of CO.sub.2 capture and storage.

Methods, processes, compositions, systems and uses for separating acidic gases such as carbon dioxide from a gaseous mixture containing such acidic gases, utilising a dispersion of at least one organic base and a base oil, the dispersion further comprising at least one surfactant.

A system and a process for capturing Carbon Dioxide (CO.sub.2) from flue gases are disclosed. The process comprises feeding a flue gas comprising CO.sub.2 to at least one Rotary Packed Bed (RPB) absorber rotating circularly. A solvent may be provided through an inner radius of the RPB absorber. The solvent may move towards an outer radius of the RPB absorber. The solvent may react with the flue gas in a counter-current flow. The process further includes passing the flue gas through at least one of a water wash and an acid wash to remove traces of the solvent present in the flue gas. Finally, the solvent reacted with the CO.sub.2 may be thermally regenerated for re-utilizing the solvent back in the process.

A gas separation process for treating exhaust gases from combustion processes. The invention involves routing a first portion of the exhaust stream to a carbon dioxide capture step, while simultaneously flowing a second portion of the exhaust gas stream across the feed side of a membrane, flowing a sweep gas stream, usually air, across the permeate side, then passing the permeate/sweep gas back to the combustor.
