Process and apparatus for separation of components of a gas stream
| DWPI Title: Apparatus for separating higher and lower density gas components, has gas mixture provided with higher density gas component and lower density gas component, where gas mixture flows in spiral path along length dimension of channel |
| 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. |
| Use: Apparatus for separating higher and lower density gas components. |
| Advantage: The apparatus is capable of separating higher and lower density gas components in an efficient and cost-effective manner. |
| Novelty: The apparatus has a slot provided with two opposing sidewalls defined by length and height dimensions, a top wall defined by width and length dimensions, and a bottom wall defined by the width and the length dimensions. One of the two opposing sidewalls is maintained at temperature less than the other opposing sidewall. A gas mixture is provided with a higher density gas component and a lower density gas component, where the gas mixture flows in a spiral flow path (18) along length dimension of a gas separation channel (16). |
