A method and a plant for capturing CO2 from an incoming flue gas. The flue gas can be exhaust gas from coal and gas fired power plants, cement factories or refineries. The incoming exhaust gas is cooled, mixed with air and compressed, and thereafter introduced into a combustion chamber together with gas and/or liquid fuel. Part of the combustion is achieved by separate burners with cooling/combustion air feed with a volume equal to the volume of CO2 captured. Said burners will elevate the temperature in the combustion chamber allowing combustion of exhaust gas with low oxygen content. CO2 is captured at high partial pressure before expansion by the gas turbine to produce power and generate steam in the heat recovery unit. The gas turbine will operate with high efficiency close to design parameters with respect to inlet temperature, pressure and flow.

Provided is a method for upgrading a bio-based material, the method including the steps of pre-treating bio-renewable oil(s) and/or fat(s) to provide a bio-based fresh feed material, hydrotreating the bio-based fresh feed material, followed by separation, to provide a bio-propane composition.

A thermal diffusion unit is fluidly connected to a combustion engine via a flue line. The thermal diffusion unit has a plurality of plates assembled in a parallel configuration, including a pair of heating plates having a heating fluid gap extending therebetween and a pair of cooling plates having a cooling fluid gap extending therebetween. A diffusion sheet is positioned between the pair of heating plates and the pair of cooling plates, such that the diffusion sheet interfaces on a first side with one of the heating plates and interfaces on an opposite side with one of the cooling plates. The diffusion sheet includes a plurality of interconnected thermal diffusion cells arranged in a repeating pattern, at least one heated passage fluidly connecting adjacent thermal diffusion cells, and at least one cooled passage fluidly connecting adjacent thermal diffusion cells.

An air purification system includes a conduit extending between an inlet and an outlet, each in fluid communication with an enclosed environment. Ambient air from the enclosed environment enters the conduit via the inlet and treated air exits the conduit and enters the enclosed environment via the outlet. The system further includes a fibrous filter disposed within the conduit and configured to treat the ambient air thereby generating the treated air, and a renewal unit disposed within the conduit and configured to renew the fibrous filter.

The invention generally relates to a process for purifying a hydrogen gas for use in a fuel cell. The process involves taking a hydrogen feed stream from a high-pressure tank and passing it through a purifier comprising an adsorbent to provide a purified hydrogen stream which is sent to a fuel cell. A particular adsorbent which can be used is a metal-organic framework composition. The adsorbent can be housed in a device such as a canister or cartridge having an inlet and outlet port.

The disclosure provides a method of treating flue gas that has one or more components. The method comprises passing a solution through both a magnetic field and an electric field to form an activated solution. The method also comprises contacting the activated solution with the flue gas so that the one or more components of the flue gas are at least partially absorbed by the activated solution to form a residue solution.
