  • Publication number: 20110132032
    Abstract: A method and apparatus in which air is liquefied and stored for later energy recovery during which the liquid air is pumped to high pressure, heated and then expanded to recover the energy. During the recovery of energy, the pumped liquid air is heated within a regenerator that stores the refrigeration within the liquid air. During the liquefaction of the air, part of the refrigeration required is obtained from the refrigeration stored in the regenerator.

  • Patent number: 7871457
    Abstract: A method of producing a carbon dioxide product stream from a synthesis gas stream formed within a hydrogen plant having a synthesis gas reactor, a water-gas shift reactor, located downstream of the synthesis gas reactor to form the synthesis gas stream and a hydrogen pressure swing adsorption unit to produce a hydrogen product recovered from the synthesis gas stream. In accordance with the method the carbon dioxide from the synthesis gas stream by separating the carbon dioxide from the synthesis gas stream in a vacuum pressure swing adsorption system, thereby to produce a hydrogen-rich synthesis gas stream and a crude carbon dioxide stream and then purifying the crude carbon dioxide stream by a sub-ambient temperature distillation process thereby to produce the carbon dioxide product. A hydrogen synthesis gas feed stream to the hydrogen pressure swing adsorption unit is formed at least in part from the hydrogen rich stream.

  • Publication number: 20030161780
    Abstract: A method and a system for supplying a carbon dioxide fluid feed from a carbon dioxide purifying means to one or more applications. The feed is combined with contaminants at the applications to form an effluent, and at least one effluent is returned to the purifying means for recycling the carbon dioxide. Carbon dioxide from a carbon dioxide source is combined with the carbon dioxide of the system so that the purity of the carbon dioxide from the source is upgraded prior to the applications.
