초록

Gas separation is facilitated by imposing cyclic gas flow and pressure variations on a gas mixture in an adsorption column from the opposite ends thereof. By employing specified relative volume displacements and phase angles for such cyclic variations, the productivity of desired product is enhanced.

청구항

An improved pressure swing adsorption process for separating a more readily adsorbable gas component(s) from less readily adsorbable gas component(s) of a gas mixture comprising: (a) introducing said gas mixture to an adsorption column, containing an adsorbent capable of selectively adsorbing the more readily adsorbable gas component(s) of said gas mixture, at a point between the opposite ends of the column; (b) imposing cyclic gas flow and pressure variations on the gas mixture in said column from a first end thereof by a first, larger, cyclic volume di...
