Abstract: A method and a system of abating carbon dioxide (CO2) and/or hydrogen sulfide (H2S) in a geological reservoir. Water is pumped or transferred from a water source to an injection well. The gasses are merged with the water under conditions where the hydraulic pressure of the water is less than the pressure of CO2 and/or H2S gas at the merging point. The water with CO2 and/or H2S gas bubbles is transferred further downwardly at a certain velocity higher than the upward flow velocity of said CO2 and/or H2S gas bubbles ensuring downward movement of gas bubbles resulting in full dissolution of said CO2 and/or H2S in the water due to elevating pressure.

Abstract: This invention relates to a method and a system of abating carbon dioxide (CO2) and/or hydrogen sulfide (H2S) in a geological reservoir. Water is pumped or transferred from a water source to an injection well. The gasses are merged with the water under conditions where the hydraulic pressure of the water is less than the pressure of CO2 and/or H2S gas at the merging point. The water with CO2 and/or H2S gas bubbles is transferred further downwardly at a certain velocity higher than the upward flow velocity of said CO2 and/or H2S gas bubbles ensuring downward movement of gas bubbles resulting in full dissolution of said CO2 and/or H2S in the water due to elevating pressure. The complete dissolution ensures a lowered pH of the water entering a geological (e.g. geothermal) reservoir which is needed to promote mineral reactions leading to CO2 and H2S abatement This abatement may be quantified by dissolving a tracer substance in a predetermined molar ratio to said dissolved CO2 and/or H2S and monitored in a monitoring well.

Abstract: The invention provides a method of molding composite material aerofoil, comprising steps of (i) providing a mold having the desired three-dimensional shape; (ii) providing a first layer over the mold that adheres to the mold and has a non-adhesive outer surface; (iii) applying composite material over the first layer; (iv) laying a moldable sheet over the composite material; (v) curing the resulting assembly and (vi) removing the moldable sheet and mold to leave an intact one-piece aerofoil structure.
