摘要: Method of operating a pressure swing adsorption system having a plurality of parallel adsorber vessels and a plurality of valves and gas manifolds adapted to introduce gas into each adsorber vessel and withdraw gas from each adsorber vessel in a cyclic series of sequential process steps. A leaking valve may be identified by (1) determining a value of an operating parameter that is a function of the mass of gas provided to a receiving adsorber vessel or withdrawn from an adsorber vessel during a selected process step, portion of a process step, or series of process steps; (2) determining the deviation of the value of the operating parameter from a predetermined reference value; and (3) using the magnitude and direction of the deviation to determine whether any valves are leaking.

摘要: Method for the separation of a gas mixture comprising providing a pressure swing adsorption system having a plurality of adsorber vessels, wherein each vessel has an inlet, an outlet, and a bed of particulate adsorbent material disposed therein. The adsorbent material is selective for the adsorption of one or more components from the gas mixture, and each bed of adsorbent material is characterized by a bed depth and by an average particle diameter less than about 1.3 mm. A feed step is carried out during a feed time period wherein the gas mixture is introduced into the adsorber vessel, one or more components are selectively adsorbed from the gas mixture, and a product gas is withdrawn from the adsorber vessel. The bed depth in feet times the dimensionless ratio of the empty bed residence time to the feed time period is less than about 4.

摘要: Method for the separation of a gas mixture comprising providing a PSA system with at least one adsorber vessel containing adsorbent material that is selective for the adsorption of carbon monoxide and nitrogen, passing a feed gas mixture containing at least hydrogen and carbon monoxide and optionally containing nitrogen through the adsorbent material in a feed step and withdrawing a purified hydrogen product from the adsorber vessel, wherein the feed step has a duration or feed time period of about 30 seconds or less. The adsorbent material is characterized by any of (1) a Henry's law constant for carbon monoxide between about 2.5 and about 5.5 (mmole/g)/atm; (2) a carbon monoxide heat of adsorption between about 6.0 and about 7.5 kcal/gmole; (3) a Henry's law constant for nitrogen greater than about 1.5 (mmole/g)/atm; and (4) a selectivity of carbon monoxide to nitrogen between about 5.0 and about 8.0.
