Enriching atmosphere inside floating greenhouse with carbon dioxide obtained from waste gas emissions, e.g. for market gardening, involves storing carbon dioxide-rich liquid phase inside floating body

摘要

A carbon dioxide-rich liquid phase is stored inside a floating body (5) associated with the greenhouse (1), before the carbon dioxide is separated from the liquid in a desorption device (4). A method for enriching the atmosphere inside a floating greenhouse comprising a floating body containing carbon dioxide involves: (1) removing carbon dioxide from a waste gas emission by gas/liquid separation in an absorption device, to form a carbon dioxide-rich liquid phase and a waste gas with a low carbon dioxide content; (2) removing carbon dioxide from the liquid phase by gas/liquid separation in a desorption device, to form a liquid phase with a low carbon dioxide content and carbon dioxide; and (3) supplying the carbon dioxide to the floating greenhouse. The carbon dioxide-rich liquid phase is stored inside the floating body between steps (1) and (2).
