20140137779 | NEAR ZERO EMISSIONS PRODUCTION OF CLEAN HIGH PRESSURE STEAM - Substantially pure high pressure steam is produced within a high pressure heat exchanger. Heat for the high pressure heat exchanger is provided from an outlet of an oxy-fuel combustion gas generator which discharges a steam/CO | 05-22-2014 |

20130022537 | HYDROGEN PRODUCTION FROM AN OXYFUEL COMBUSTOR - A method is provided for hydrogen production from a hydrogen and carbon containing fuel combusted within an oxyfuel combustor. The oxyfuel combustor combusts hydrogen and carbon containing fuel with oxygen at a non-stoichiometric ratio, typically fuel rich. In such an operating mode, products of combustion include steam, carbon dioxide, carbon monoxide and hydrogen. These products of combustion are then passed through a hydrogen separator. Remaining products of combustion can be optionally combusted at a stoichiometric ratio with oxygen in a second oxyfuel combustor discharging substantially only steam and carbon dioxide. A turbine or other expander can be provided downstream from the gas generator to produce power and eliminate carbon monoxide from the system. The system can be operated in a second mode where the gas generator combusts the fuel with oxygen at a stoichiometric ratio to maximize electric power generation without hydrogen production at periods of peak power demand. | 01-24-2013 |
20120160187 | ZERO EMISSION STEAM GENERATION PROCESS - This invention provides a new process to generate steam directly from untreated water produced simultaneously with thermally recovered crude oil, and to inject the steam and combustion products into a hydrocarbon reservoir to recover hydrocarbons and to sequester a portion of the carbon dioxide produced during the creation of steam. The invention removes the ongoing additional water requirements for thermal oil recovery and the need for surface treating of produced water for re-use, yielding improved process efficiencies, reduced environmental impact, and improved economic value. | 06-28-2012 |
