摘要:
Containerized gas separation system comprising (a) a container having an interior, an exterior, and an exterior volume defined by the exterior dimensions of the container and (b) a pressure swing adsorption system installed in the interior of the container and adapted to recover a product gas from a feed gas mixture, the pressure swing adsorption system being adapted to deliver the product gas at a product gas flow rate, wherein the ratio of the exterior volume of the container to the product gas flow rate is less than about 2000 ft 3 /(ton per day).
摘要:
Apparatus (1) for providing positive airway pressure therapy comprising a mask (3) adapted for the delivery of pressurized air to maintain positive airway pressure in a patient's airway and an air pump system (5) comprising a plurality of pump elements adapted to supply pressurized air to the mask, wherein the air pump system (5) is attached directly to the mask (3) or is adapted to be worn on a part of the patient's body spaced apart from the mask (3).
摘要:
Rapid cycle pressure swing adsorption processes, systems and apparatus for the separation of a multi-component feed gas mixture by selectively adsorbing at least one more readily adsorbable component in a bed of adsorbent material are provided. The ratio of a bed depth and a bed volume is low and the pressure gradient in the bed exceeds 9,49 kPa/m (0.035 psi/inch) during the feed step.
摘要:
Hydrogen is purified from a feed gas mixture including hydrogen and at least one impurity selected from carbon monoxide and nitrogen using an adsorption apparatus having a discharge end adsorption layer containing an adsorbent with a Henry's law constant (K H ) at 70°F (21°C) for the impurity from 0.8 to 2.2 mmole/g/atm (0.1 MPa) for carbon monoxide or from 0.55 to 1.4 mmole/g/atm (0.1 MPa) for nitrogen. High purity (99.99+%) hydrogen can be obtained.
