20150157957 | METHOD AND APPARATUS FOR COOLING A FLOW CONTAINING AT LEAST 35% CARBON DIOXIDE AND MERCURY - In a method for cooling a flow containing at least 35% carbon dioxide and at least 0.2 μg/Nm | 06-11-2015 |
20150174523 | PROCESS AND APPARATUS FOR THE SEPARATION OF A STREAM CONTAINING CARBON DIOXIDE, WATER AND AT LEAST ONE LIGHT IMPURITY INCLUDING A SEPARATION STEP AT SUBAMBIENT TEMPERATURE - In a process for the separation of a stream containing carbon dioxide, water and at least one light impurity including a separation step at subambient temperature, the feed stream is compressed in a compressor comprising at least two stages to form a compressed feed stream, the compressed feed stream is purified in an adsorption unit to remove water and form a dried compressed stream, the dried compressed stream or a stream derived therefrom is cooled to a subambient temperature and separated by partial condensation and/or distillation in a separation apparatus, liquid enriched in carbon dioxide is removed from the separation apparatus, the adsorption unit is regenerated using a regeneration gas and the regeneration gas is formed by separating, by permeation in a permeation unit, the dried compressed stream or a gas derived therefrom, the permeate of the permeation unit constituting the regeneration gas. | 06-25-2015 |
20150276309 | Process and Apparatus for Separating NO2 from a CO2 and NO2- Containing Fluid - A process for separating carbon dioxide from a fluid containing carbon dioxide, NO | 10-01-2015 |
20150300734 | Method for Separating a Carbon Dioxide-rich Gas by Partial Condensation and Permeation - A carbon dioxide-rich gas is cooled in a first heat exchanger; the carbon dioxide-rich gas cooled in the first heat exchanger enters a first phase separator at a first temperature between −50° C. and −53° C.; a carbon dioxide-enriched liquid is drawn from the first phase separator and acts as product; a carbon dioxide-depleted gas from the first separator is reheated in the first exchanger to a second temperature between −35° C. and −45° C., without having been expanded downstream from the first phase separator and enters a permeation unit at the second temperature; the reheated gas is subjected to at least one permeation step in the permeation unit in order to produce at least two fluids which are then reheated in the first exchanger, the fluid from the permeation unit, reheated in the exchanger, which exits the permeation unit at the lowest temperature, being at a temperature of more than −54° C. | 10-22-2015 |
20150315020 | METHOD FOR PRODUCING HYDROGEN BY REFORMING HYDROCARBONS USING STEAM, COMBINED WITH CARBON DIOXIDE CAPTURE AND STEAM PRODUCTION - A method for producing hydrogen by reforming hydrocarbons using steam, combined with carbon dioxide capture and steam production, which involves mixing the hydrocarbons to be reformed with steam in order to produce the feedstock for the reforming, generating a syngas; the syngas is then cooled, and enriched with H | 11-05-2015 |
20150321914 | METHOD FOR PRODUCING HYDROGEN BY REFORMING HYDROCARBONS USING STEAM, COMBINED WITH CARBON DIOXIDE CAPTURE AND STEAM PRODUCTION - A method for producing hydrogen by reforming hydrocarbons using steam, combined with carbon dioxide capture and steam production, which involves mixing the hydrocarbons to be reformed with steam in order to produce a feedstock for reforming, generating a syngas; the syngas produced is cooled, enriched with H2 and CO2, and then cooled; the condensates of the method are separated from the syngas in order to be used in the method, the saturated syngas being treated by adsorption with pressure modulation so as to produce hydrogen and a gaseous effluent containing CO | 11-12-2015 |
20160003530 | METHOD AND APPLIANCE FOR SEPARATING A MIXTURE CONTAINING CARBON DIOXIDE BY CRYOGENIC DISTILLATION - In a method for separating at least one lighter impurity of a gaseous mixture containing at least 30% mol of carbon dioxide, a liquid ( | 01-07-2016 |
20160003533 | SEPARATION AT SUB-AMBIENT TEMPERATURE OF A GASEOUS MIXTURE CONTAINING CARBON DIOXIDE AND A LIGHTER CONTAMINANT - A device for separating a gas mixture containing at least 35 mol % carbon dioxide and also at least one gas lighter than carbon dioxide, comprising a first phase separator configured to receive a first partially condensed flow from an exchange line; a first phase separator configured to separate the gas phase from the liquid phase; a cooling means configured to receive the gas phase from the first phase separator and cool said gas phase to form a second partially condensed flow. The resulting liquid phase is then sent to a first valve and is expanded to a lower pressure that is at most 300 mbar lower in order to form a first expanded liquid, which is then mixed with a second liquid originating from the second phase separator in a mixing means that is located upstream of a third valve. | 01-07-2016 |
