Abstract:
1. An apparatus for separating higher and lower density gas components comprising: an elongated gas separation channel having a length dimension, L, and having a cross-sectional shape defining a slot having a width dimension, W, and a height dimension, H; an open gas entry side configured to accept a gas flow; an open gas exit side; wherein the slot comprises two opposing sidewalls defined by the length and height dimensions, a top wall defined by the width and the length dimensions, and a bottom wall defined by the width and the length dimensions; wherein one of the two opposing sidewalls is maintained at a temperature less than the other one of the two opposing sidewalls; and wherein the slot is skewed into a parallelogram shape that is defined by a negative skew angle, β<0, (i.e., in a counter-clockwise direction); wherein the skew angle is measured between a sidewall and a Y-axis; and wherein the Y-axis coincides with the direction of gravity.
