Abstract: Various embodiments address removal of one or more species from a gas stream by exposing the gas stream to divided portions of a fluid, such as droplets of water or mist, where the fluid, and/or content of the fluid, can absorb or modify the species and thereby remove it at least partially from the gas stream. Removal of CO2 from a combustion exhaust stream is one embodiment.

Abstract: The invention relates to a mixture based on white slag resulting from the production of steel and calcium carbide sludge resulting from the process of acetylene preparation, the mixture being used to sequester carbon from flue gases, thus reducing the concentration of carbon dioxide CO2 discharged into atmosphere. According to the invention, the mixture consists of the following components expressed as a percentage by weight: 50% white slag resulting as a by-product of the steelmaking process, with a grain size between 71 and 315 pm, having a pH = 12.1 and 50% calcium carbide sludge resulting from acetylene preparation, with a liquid/solid mass ratio = 1:1 and pH = 12.2.

Abstract: A system (100) for generating and using carbon dioxide comprises: (a) a closed system combustion stage (38) for combusting a fuel in a furnace and producing an off gas containing carbon dioxide (44); and (b) an algae growth and oxygen generation stage (10) for receiving off gas generated in the closed system combustion stage (38) wherein the algae growth and oxygen generation stage (10) through the action of algae: (i) converts carbon dioxide (44) to a chemical product, and oxygen; and (ii) provides a gas stream (37) to the closed system combustion stage (38), the gas stream comprising oxygen and carbon dioxide. The closed system combustion stage (38) may, for example, be conducted in a power station. The system (100) is also suitable for integration with crop cultivation, for example sugar cultivation, where carbon dioxide (44) for algal growth may be sourced from combustion of plant material, fermentation of plant material or both.

Abstract: The invention relates to a plant and a method for the production of decarbonised hydrogen using carbonate, water, gas containing hydrocarbons and electricity. The plant 100 first of all comprises an electric calciner 10, a contactor 20, an apparatus for correcting the pH 30 and a metering device 40. The plant 100 is suitable for receiving electrical energy, carbonate, water, natural gas at its input and for releasing decarbonised hydrogen at its outlet and an alkaline water rich in bicarbonates which, once released into the sea, represents the permanent storage for CO2. The plant 100 uses bicarbonates as permanent storage of CO2 in the sea: this storage allows the production of decarbonised hydrogen at low costs and in modular plants.

Abstract: THIS invention relates to a method of sequestering CO2 containing gas with the preparation of a high surface area of rock suited for sequestration in a 3-dimensional permeable heap. The method includes includes the steps of obtaining, or obtaining and comminuting, a material 10 which is suitable for CO2 sequestration to generate a feed stock with a p80 less than 5mm. Separating the feedstock into a coarse fraction 16 and a fine fraction 16, and agglomerating 20 the fine fraction to form an agglomerated particles 22 with an apparent p80 of less than 10mm and with a p10 > 0.15mm. The agglomerated particles are stacked in a heap 18, and a CO2 containing gas, and an irrigant 26, through the permeable and unsaturated heap, to sequester 24 the CO2 contained in the gas.
