Title (DE) VERFAHREN UND VORRICHTUNG ZUR BEHANDLUNG EINES KOHLENDIOXIDHALTIGEN GASSTROMS AUS EINER GROSSFEUERUNGSANLAGE
(EN) METHOD AND DEVICE FOR TREATING A GAS FLOW COMPRISING CARBON DIOXIDE FROM A LARGE COMBUSTION PLANT

Abstract:
(DE) Die Erfindung betrifft ein Verfahren und eine Vorrichtung zur Behandlung eines kohlendioxidhaltigen Gasstroms aus einer Großfeuerungsanlage, insbesondere eines Kraftwerks. Der Gasstrom wird in einer Kohlendioxidreinigungsstufe R in einen Teilgasstrom mit erhöhtem Kohlendioxidgehalt und einen Teilgasstrom mit vermindertem Kohlendioxidgehalt aufgetrennt. Der Teilgasstrom mit erhöhtem Kohlendioxidgehalt wird einer Weiterverwertung und/oder Speicherung S zugeführt. Insbesondere kann durch Verpressung des Kohlendioxids im Untergrund die Emission klimaschädlicher Gase vermindert werden. Zur Erhöhung des verpressbaren CO2- Anteils wird vorgeschlagen, dass der Teilgasstrom mit vermindertem Kohlendioxidgehalt einer Druckwechseladsorptionsstufe PSA zugeführt wird, in der eine kohlendioxidreiche und eine kohlendioxidarme Fraktion erzeugt werden. Die kohlendioxidreiche Fraktion wird zur Kohlendioxidreinigungsstufe R zurückgeführt oder direkt der Weiterverwertung und/oder Speicherung S zugeführt.
(EN) The invention relates to a method and to a device for treating a gas flow comprising carbon dioxide from a large combustion plant, particularly a power plant. The gas flow is separated in a carbon dioxide scrubbing stage R into a partial gas flow having increased carbon dioxide content and a partial gas flow having reduced carbon dioxide content. The partial gas flow having increased carbon dioxide content is fed into a further processing and/or storage unit S. In particular, by compressing the carbon dioxide in the bedrock, the emission of climate-damaging gases can be reduced. In order to increase the proportion of compressible CO2, the invention proposes that the partial gas flow having reduced carbon dioxide content is fed into a pressure swing adsorption stage PSA, wherein a fraction rich in carbon dioxide and a fraction having low carbon dioxide content are generated. The fraction rich in carbon dioxide is fed back into the carbon dioxide scrubbing stage R, or fed directly into the further processing and/or storage unit S.
(FR) L'invention concerne un procédé et un dispositif de traitement d'un courant de gaz contenant du dioxyde de carbone provenant d'une grande installation de combustion, notamment d'une centrale électrique. Le courant de gaz est séparé lors d'une première étape de purification de dioxyde de carbone R en un courant partiel de gaz ayant une teneur accrue en dioxyde de carbone et un courant partiel de gaz ayant une teneur réduite en dioxyde de carbone. Le courant partiel de gaz ayant une teneur accrue en dioxyde de carbone est acheminé vers une valorisation ultérieure et/ou un stockage S. L'émission de gaz nuisibles pour le climat peut être réduite notamment par compression du dioxyde de carbone dans le sous-sol. Pour augmenter la fraction de CO2 compressible, il est proposé que le courant partiel de gaz ayant une teneur réduite en dioxyde de carbone soit acheminé vers une étape d'adsorption à pression alternée PSA dans laquelle une fraction riche en dioxyde de carbone et une fraction pauvre en dioxyde de carbone sont produites. La fraction riche en dioxyde de carbone est acheminée vers l'étape de purification de dioxyde de carbone R ou est acheminée directement vers la valorisation ultérieure et/ou le stockage S.
