  • Patent number: 8795413
    Abstract: The object of the invention is a method for dissolving carbon dioxide from flue or other gas and for the neutralization of the solution obtained. The gas, in which the partial pressure of carbon dioxide is at least 0.4 bar, is led to a dissolution process, where the major part of the carbon dioxide is dissolved into a flow of water. The aqueous solution of carbon dioxide thus obtained is neutralized by passing it through a material containing feldspar minerals, at which time the hydrogen ions of said solution are replaced by ions of alkali or alkaline earth metals, and the aluminum in said material is converted into aluminum compounds that can be separated and utilized.

  • Patent number: 8771407
    Abstract: Various apparatus provide for spraying high velocity droplets of liquid into a low velocity gas stream. Finely atomized droplets may quickly transfer their momentum to the gas, resulting in deceleration of the spray and acceleration of the gas. A high velocity spray of atomized liquid may transfer a substantial fraction of its kinetic energy to the gas before contacting a surface, in some aspects, suspended particles in the gas phase may be removed by high velocity liquid droplets passing through the gas. Certain aspects provide for controlling a gas flow by controlling the relative amounts of upstream and downstream momenta transferred to the gas by one or more liquid sprays.

  • Patent number: 8753439
    Abstract: A process and apparatus for separating a gas mixture comprising providing a slot in a gas separation channel (conceptualized as a laterally elongated Clusius-Dickel column), having a length through which a net cross-flow of the gas mixture may be established; applying a higher temperature to one side of the channel and a lower temperature on an opposite side of the channel thereby causing thermal-diffusion and buoyant-convection flow to occur in the slot; and establishing a net cross-flow of a gas mixture comprising at least one higher density gas component and at least one lower density gas component along the length of the slot, wherein the cross-flow causes, in combination with the convection flow, a spiraling flow in the slot; and wherein the spiral flow causes an increasing amount of separation of the higher density gas from the lower density gas along the length of the channel. The process may use one or more slots and/or channels.
