20080289820 | Combined Hydrogen Production and Unconventional Heavy Oil Extraction - A method of producing hydrogen and extracting heavy oil from underground reserves is provided. This method includes providing a carbon monoxide source stream and a water vapor stream to a first reactor, wherein the first reactor comprises a water shift reactor and a membrane-type separation device. This method also includes separating the products of the water shift reactor, thereby producing at least a hydrogen-rich stream, and a high pressure off-gas stream. This method also includes providing the high pressure off-gas stream and an oxidant stream to a combustion chamber. This method also includes combusting the oxidant stream and the high pressure off-gas stream as at least part of a combustion cycle thereby producing a hot injection gas stream. This method also includes combining the hot injection gas stream with a liquid water stream, wherein the combined stream may be used to heat the underground reserve sufficiently to release petroleum hydrocarbons therefrom. | 11-27-2008 |
20080223075 | Process and Apparatus for the Separation of Air by Cryogenic Distillation - A process for separating air by cryogenic distillation in a column system comprising a high pressure column and a low pressure column comprises compressing all the feed air in a first compressor to a first outlet pressure, sending a first part of the air at the first outlet pressure to a second compressor and compressing the air to a second outlet pressure, cooling at least part of the air at the second outlet pressure in a heat exchanger liquefying at least part of the air at the second outlet pressure and sending the liquefied air to at least one column of the column system wherein at least 50% of the liquefied air sent to the column system has been compressed in the second compressor, cooling a second part of the air at the first outlet pressure in the heat exchanger and expanding at least part of the second part of the air in an expander from the first outlet pressure to the pressure of a column of column system and sending the expanded air to that column, at least partially vaporizing an auxiliary fluid, eventually further warming said auxiliary fluid in the heat exchanger, sending at least part of this auxiliary fluid to a third compressor to a third outlet pressure, introducing at least part of said auxiliary fluid at said third outlet pressure in the heat exchanger, cooling said auxiliary fluid and at least partially liquefying said auxiliary fluid, removing said auxiliary stream from the heat exchanger and expanding it to a fourth pressure level before reintroducing it in the heat exchanger where it will be partially vaporized as above-mentioned, removing liquid from a column of the column system and vaporizing the liquid by heat exchange in the heat exchanger. | 09-18-2008 |
