    摘要： A process is provided for recovering oxygen-rich gas by enriching gaseous oxygen contained in crude gas by a single-tank PSA process which utilizes a single adsorption tower loaded with an adsorbent. A cycle is repeated including introducing crude gas into the adsorption tower, desorbing unnecessary components from the adsorbent, introducing washing gas into the adsorption tower for discharging the remaining gas from the adsorption tower, and raising the internal pressure of the adsorption tower. The desorbing includes recovering semi-enriched oxygen gas existing in the adsorption tower after finishing of the adsorption for retention in a recovery tank. The introduction of washing gas includes introducing part of the semi-enriched oxygen gas existing in the recovery tank into the adsorption tower as the washing gas. Raising the internal pressure includes introducing the rest of the semi-enriched oxygen gas retained in the recovery tank into the adsorption tower.

    摘要： This invention includes a pair of chambers each containing a piston which is reciprocated slowly by a computer controlled reversible fluid pressure pump between an advanced position for moving room air through a molecular sieve bed to strip nitrogen from the air and deliver oxygen enriched air to a patient, and a retracted position to back-flush the sieve bed with oxygen enriched air and exhaust the nitrogen rich air to the atmosphere. The pistons may be moved by piston rods or by a rack and pinion drive. In a third embodiment a single cylinder forms a pair of chambers separated by a central exhaust chamber, and expandable bellows in the chambers extend and retract either alternatively or simultaneously. In a fourth embodiment a single cylinder containing a single piston forms a pair of chambers one on each side of the piston and a molecular sieve bed communicates with each chamber.

    摘要： A pressure swing adsorption process for the separation of a pressurized feed gas containing at least one more strongly adsorbable component and at least one less strongly adsorbable component. The process comprises (a) introducing the pressurized feed gas into a feed end of an adsorber bed containing one or more solid adsorbents which preferentially adsorb the more strongly adsorbable component and withdrawing from a product end of the adsorber bed a first adsorber effluent gas enriched in the less strongly adsorbable component, wherein the first adsorber effluent gas is utilized as final product gas; (b) terminating the introduction of the pressurized feed gas into the adsorber bed while withdrawing from the product end of the adsorber bed a second adsorber effluent gas enriched in the less strongly adsorbable component, wherein the pressure in the adsorber bed decreases while the second adsorber effluent gas is withdrawn therefrom, and wherein the second adsorber effluent gas is utilized as additional final product gas; (c) depressurizing the adsorber bed to a minimum bed pressure by withdrawing additional gas therefrom; (d) repressurizing the adsorber bed by introducing repressurization gas into the bed, wherein at least a portion of the repressurization gas is provided by pressurized feed gas; and (e) repeating steps (a) through (d) in a cyclic manner. No final product gas is required for purge or repressurization in the process cycle steps.

    摘要： The flow of gas between two vessels, each of which undergoes cyclic changes in gas pressure, is controlled by two check valves installed in parallel between the vessels. The first check valve allows gas to flow from the first vessel to the second vessel when the differential pressure between the vessels exceeds a first value, and the second check valve allows gas to flow from the second vessel to the first vessel when the differential pressure between the vessels exceeds a second value. The gas flow control method is particularly useful in pressure swing adsorption processes.

    摘要： A total delivery oxygen concentration system is provided to supply concentrated oxygen to end users having a variety of oxygen capacity requirements. The system includes a first oxygen concentrating device that may be operated either singularly to produce a first flow of concentrated oxygen or in conjunction with a supplemental oxygen concentrating device. When operating in conjunction with the supplemental oxygen concentrating device, the first oxygen concentrating device serves as a source of compressed air for the supplemental oxygen concentrating device and receives a second flow of concentrated oxygen from the supplemental oxygen concentrating device to provide a combined concentrated oxygen flow to the end user.
