  • Removal of nitrogen oxide from gas streams
    Patent number: 6136283
    Abstract: Temperature rise during the exothermic reduction of nitrogen oxides contained in a carbon dioxide-rich gas stream to nitrogen by contacting the gas stream with ammonia in a reactor containing a reduction catalyst is controlled by recycling a portion of the gaseous effluent from the reactor to the gas stream prior to its introduction into the reactor, thereby cooling the reactor contents without diluting the carbon dioxide in the effluent.
    Type: Grant
    Filed: November 26, 1997
    Date of Patent: October 24, 2000
    Assignee: The BOC Group, Inc.
    Inventor: Sidney Simon Stern
  • Process for the production of petrochemicals
    Patent number: 6002019
    Abstract: Petrochemicals are produced by the vapor phase reaction of a hydrocarbon with air in the presence of a suitable catalyst. The petrochemical product is removed from the product gas stream, and part or all of the remaining gas stream is passed through a bed of hydrophobic adsorbent, which adsorbs mainly the unreacted hydrocarbon from the gas stream without adsorbing water vapor. The adsorbed hydrocarbon is purged from the bed with air, and the air-hydrocarbon mixture is recycled to the partial oxidation reactor.
    Type: Grant

    Date of Patent: December 14, 1999
    Assignee: The Boc Group, Inc.
    Inventors: Satish S. Tamhankar, Divyanshu R. Acharya, Sidney Simon Stern
  • Air separation method and apparatus
    Patent number: 5711166
    Abstract: A method and apparatus of separating air in which the air is rectified wig a single column nitrogen generator which produces a nitrogen stream which is expanded into a refrigerant stream and then taken as a medium pressure product. Oxygen enriched air can be taken as low pressure and medium pressure enriched air products. A stream of oxygen enriched air can be used to regenerate the pre-purification unit and also taken as a wet product.

    Inventors: Anish Mehta, Sidney Simon Stern
  • Cooling process for subambient and above ambient temperatures
    Patent number: 4015439
    Abstract: The present invention relates to the provision for cooling in systems where above ambient cooling temperatures are indicated, for at least certain system services, while water as a coolant therein is contraindicated.
