Method and arrangement for separating carbon dioxide from a feed stream containing carbon dioxide

A method for separation of carbon dioxide from a carbon dioxide-containing feed stream, comprising:

• subjecting at least a part of the feed stream to a temperature swing adsorption to obtain a first successive stream and a second successive stream, the first successive stream being depleted in carbon dioxide and the second successive stream being enriched in carbon dioxide, in each case in relation to the feed stream, and
• subjecting at least a part of the second successive stream to a membrane separation to obtain a third successive stream and a fourth successive stream, the third successive stream being depleted in carbon dioxide and the fourth successive stream being enriched in carbon dioxide, in each case relative to the second successive stream,
• subjecting at least a part of the fourth successive stream to a compression and partial liquefaction in a heat exchanger to obtain a gaseous fraction and a liquid fraction, the gaseous fraction being depleted in carbon dioxide and the liquid fraction being enriched in carbon dioxide, in each case relative to the fourth successive stream, and
• subjecting at least a part of the gaseous fraction to the temperature swing adsorption together with the feed stream and subjecting at least part of the liquid fraction to an expansion and used as refrigerant in a heat exchanger for partial liquefaction.
