Beschreibung
Zusammenfassung:	Plant and process aiming at separating, from syngas or biogas mixtures, liquid methane, gaseous hydrogen, liquid carbon monoxide and gaseous carbon dioxide with high purity level, wherein the process comprises the following steps: * - purifying the gas mixture; * - cooling the purified gas mixture to obtain carbon dioxide in the solid state; * - sublimating the solid CO2 to obtain gaseous carbon dioxide with high purity level; * - fractionally cooling for the treatment of the fuel mixture separated from CO2, aiming at separating liquid methane, gaseous hydrogen, liquid carbon monoxide. L'invention concerne une installation et un procédé visant à séparer, à partir de mélanges de gaz de synthèse ou de biogaz, du méthane liquide, de l'hydrogène gazeux, du monoxyde de carbone liquide et du dioxyde de carbone gazeux avec un niveau de pureté élevé, le procédé comprenant les étapes suivantes : purification du mélange gazeux; refroidissement du mélange gazeux purifié pour obtenir du dioxyde de carbone à l'état solide; sublimation du CO2 solide pour obtenir du dioxyde de carbone gazeux avec un niveau de pureté élevé; refroidissement fractionné pour le traitement du mélange combustible séparé du CO2, afin de séparer le méthane liquide, l'hydrogène gazeux et le monoxyde de carbone liquide.
