20090101007 | Method for recovery of carbon dioxide from a gas - The present invention relates to a method for recovery of carbon dioxide from a gas stream. The method is a two-step method in which carbon dioxide is compressed in the first step, while the residual carbon dioxide is recovered by an absorption process in a subsequent step. The present invention also relates to the use of the method for the recovery of carbon dioxide and a plant for recovery of carbon dioxide. | 04-23-2009 |
20100101415 | METHOD FOR RECOVERY OF HIGH PURITY CARBON DIOXIDE - The present invention describes a method for recovery of high purity carbon dioxide, which is substantially free of nitrogen oxides. This high purity carbon dioxide is obtained by introducing into the method a step in which carbon dioxide absorbed in an absorbing agent is flashed. The present invention also discloses a plant for recovery of said high purity carbon dioxide comprising an absorption column, a flash column, a stripper column, and a down stream purification unit comprising a washing column, a dehydrator, a condenser and a distillation unit. | 04-29-2010 |
20100278711 | REMOVAL OF CARBON DIOXIDE FROM A FEED GAS - The present invention relates to a new process for removal of carbon dioxide from a feed gas, wherein the feed gas is fed to and concentrated in a stripper column (A) before condensation of the gaseous carbon dioxide. The present invention also relates to different uses of the removed carbon dioxide and to a plant for removal of carbon dioxide from the feed gas. | 11-04-2010 |
20110200517 | HIGH PURITY CO2-3 - The present invention relates to a method for recovery of high purity carbon dioxide from a gaseous source and uses thereof. More specifically, the present invention relates to the production of high purity carbon dioxide, which is substantially free of nitrogen, oxygen, nitrogen oxides, sulphurous compounds and volatile organic contaminants, particularly benzene. The present invention also relates to a method for removal of benzene from a carbon dioxide feeding gas as well as the use of said high purity carbon dioxide in foodstuffs. | 08-18-2011 |
20110265647 | METHOD FOR PURIFICATION OF CARBON DIOXIDE USING LIQUID CARBON DIOXIDE - The present invention relates to a method for removing at least one contaminant from a gaseous stream substantially comprising carbon dioxide. More specifically said method comprising the step of subjecting the gaseous stream to an absorption step in which the absorbent is liquid carbon dioxide. | 11-03-2011 |
20120006197 | METHOD FOR RECOVERY OF CARBON DIOXIDE FROM A GAS USING A PROCESS GAS HEATED REBOILER FOR CARBON DIOXIDE REMOVAL IN A STRIPPER - The present invention relates to a method for recovery of carbon dioxide from a gas (G | 01-12-2012 |
20130133363 | HIGH PRESSURE RECOVERY OF CARBON DIOXIDE FROM A FERMENTATION PROCESS - The present invention relates to a method for recovering carbon dioxide from a gaseous stream originating from a fermentation process by compression, absorption, condensation and distillation, wherein at least the absorption and condensation is performed under a high pressure of at least 30 bar. | 05-30-2013 |
20130152628 | METHOD AND PLANT FOR THE PURIFICATION OF CARBON DIOXIDE USING LIQUID CARBON DIOXIDE - The present invention relates to an improved method for removing contaminants from a gaseous stream substantially comprising carbon dioxide. More specifically, the method comprises the step of subjecting the gaseous stream to an absorption step in which the absorbent is liquid carbon dioxide wherein the waste of carbon dioxide is minimized by utilizing a compressing means for generating a pressure difference between two streams in a reboiler. | 06-20-2013 |
20140190206 | METHOD FOR PURIFICATION OF CARBON DIOXIDE USING LIQUID CARBON DIOXIDE - The present invention relates to a method for removing at least one contaminant from a gaseous stream substantially comprising carbon dioxide. More specifically said method includes the step of subjecting the gaseous stream to an absorption step in which the absorbent is liquid carbon dioxide. | 07-10-2014 |
