Patent application number | Description | Published |
20090185972 | METHODS FOR HYDROGEN STORAGE AND REFRIGERATION - A hydrogen storage system for storing hydrogen gas at elevated pressures and cryogenic temperatures is disclosed. The hydrogen gas is fed to a storage container which contains a physisorption type material and a volatile liquid container for liquid nitrogen. Cryogenic conditions are maintained within the storage container during the periods of storage and the periods where the hydrogen gas is removed from the storage system. | 07-23-2009 |
20100115970 | THERMAL MANAGEMENT APPARATUS FOR GAS STORAGE - An apparatus for storing gases such as hydrogen gas at cryogenic temperatures. The hydrogen gas is stored in a storage vessel at cryogenic temperatures and those cryogenic temperatures are sustained by a heat exchanger apparatus which provides nearly uniform distribution of a volatile liquid throughout the hydrogen gas being stored. | 05-13-2010 |
20100139485 | GAS RECOVERY PROCESS - A method for concentrating a single gas component from a gas mixture is disclosed. The method utilizes concentration units and recovery units to concentrate the single gas component which is often at very low concentrations in the gas mixture. This method allows for the recovery of a valuable gas depending upon application such as oxygen and Ar-40. | 06-10-2010 |
20110038783 | CARBON DIOXIDE PRODUCTION FOR ENHANCED OIL RECOVERY - A method for producing carbon dioxide by the steps of feeding a CO | 02-17-2011 |
20120172629 | OXIDATION METHOD AND REACTOR - A method and apparatus for increasing the concentration of oxygen in the reaction medium present in the oxidation reactor. A volume of aqueous medium from the oxidation reactor is removed and pressurized and oxygen is added to it. The oxygen-rich volume of aqueous medium is then reintroduced into the oxidation reactor at an increased pressure to ensure adequate mixing with the aqueous medium having a lower content of oxygen. | 07-05-2012 |
20130177497 | METHODS FOR THE OZONOLYSIS OF ORGANIC COMPOUNDS - A method for producing ozone for use in ozonolysis reactions. Oxygen is separated from the mixture of ozone and oxygen from an ozone generation unit and is fed back to the oxygen feed to the generation unit. Nitrogen is fed to the ozone separation unit and the mixture of nitrogen and ozone is fed to the ozonation reactor where the ozone will react with organic compounds to produce desired end products. | 07-11-2013 |
20130183219 | METHODS FOR REDUCING NITROGEN OXIDES EMISSIONS - A method to reduce the emission of contaminants such as nitrogen oxides from the operation of a submerged combustion vaporizer. Fuels are combusted and the combustion gases are fed to an aqueous system which heats up and vaporizes cryogenic fluids in tube bundles in the submerged combustion vaporizer. Ozone is added to the aqueous system and will react with the contaminants allowing for their removal from the aqueous system. | 07-18-2013 |
20130343962 | OXIDATION METHOD AND REACTOR - A method and apparatus for increasing the concentration of oxygen in the reaction medium present in the oxidation reactor. A volume of aqueous medium from the oxidation reactor is removed and pressurized and oxygen is added to it. The oxygen-rich volume of aqueous medium is then reintroduced into the oxidation reactor at an increased pressure to ensure adequate mixing with the aqueous medium having a lower content of oxygen. | 12-26-2013 |
