20130017146 | METHOD FOR PRODUCING HYDROGEN WITH REDUCED CO2 EMISSIONSAANM Darde; ArthurAACI ParisAACO FRAAGP Darde; Arthur Paris FRAANM Valentin; SoleneAACI MeudonAACO FRAAGP Valentin; Solene Meudon FRAANM Court; PhilippeAACI VincennesAACO FRAAGP Court; Philippe Vincennes FRAANM Tranier; Jean-PierreAACI L'Hay-Les-RosesAACO FRAAGP Tranier; Jean-Pierre L'Hay-Les-Roses FRAANM Traversac; XavierAACI ParisAACO FRAAGP Traversac; Xavier Paris FRAANM Terrien; PaulAACI BaltimoreAAST MDAACO USAAGP Terrien; Paul Baltimore MD US - The present invention relates to a method for producing hydrogen, with reduced carbon dioxide emissions, from a hydrocarbon mixture. In said method, the hydrocarbon mixture is reformed so as to produce a synthetic gas that is cooled, then treated in a shift reactor so as to be enriched with H2 and CO2. Optionally dried, said mixture is treated in a PSA hydrogen purification unit in order to produce hydrogen. The residue is treated by means of partial condensation with a view to capturing CO4 before said residue is sent as fuel to reforming. | 01-17-2013 |

20130340472 | METHOD AND APPARATUS FOR LIQUEFACTION OF CO2 - In a method for the liquefaction of a gas containing at least 60 mol % of CO2, in order to produce at least one liquid product, a first feed gas is compressed from a first pressure to a second pressure and cooled so as to form a liquid or supercritical flow, at least part of the liquid or supercritical flow is cooled in a heat exchanger in order to form a cyclic liquid at the second pressure, the cyclic liquid is divided into at least two fractions, including an auxiliary fraction, at least one fraction being vaporized in the exchanger by means of heat exchange with the liquid or supercritical flow part, and where there are at least two fractions, each one is vaporized at a different pressure, and the at least one gas formed is then compressed and mixed with the first feed gas, the auxiliary fraction either forming the liquid product or one of the liquid products, or being treated by separation at a sub-ambient temperature in at least one separating means in order to form the liquid product. | 12-26-2013 |
20140026611 | METHOD AND APPARATUS FOR LIQUEFYING A GAS OR COOLING A FEED GAS AT SUPERCRITICAL PRESSURE - The invention relates to a method for liquefying a feed gas or cooling a feed gas at supercritical pressure, in which the feed gas mixed with a cycle gas is condensed or cooled in order to form a supercritical gas or liquid at the first pressure, the liquid at the first pressure is cooled in a first heat exchanger (E | 01-30-2014 |
20140026612 | Method and Apparatus for Liquefying a CO2-Rich Gas - This invention relates to a method for liquefying a gas containing at least 60 mol % of CO2, in order to produce at least one liquid product, wherein the gas is cooled in order to form a fluid flow, at least a portion of the liquid or supercritical flow is cooled in a heat exchanger in order to form a cycle fluid having a cycle pressure, the cycle fluid is divided into at least two fractions including an auxiliary fraction, one of the fractions being expanded up to a first pressure in a valve in order to form a biphasic mixture, and then sent to a phase separator. The liquid fraction of the phase separator is vaporized so as to form a vaporized gas in the exchanger, the vaporized gas then being expanded from the first pressure to a second pressure in an expansion means, and then compressed in the cycle compressor and mixed with the first feed gas. | 01-30-2014 |
