METHOD OF RECOVERING CARBON DIOXIDE FROM A FLUID

摘要

A method of recovering carbon dioxide from a gaseous fluid containing carbon dioxide and other gases mutually inert to each other. The gaseous fluid is passed through silicone oils in an absorption chamber at ambient or lower temperatures where the carbon dioxide is absorbed by the silicone oils. The silicone oils, laden with carbon dioxide, is then circulated through a series of coils in contact with a heat generating apparatus. After heat from the apparatus has been picked up, the silicone oils are then transported to a desorption chamber. In the desorption chamber the silicone oils laden with carbon dioxide is agitated and further heated. This agitation and heating along with a vacuum applied to the surface of the silicone oils in the desorption chamber causes the carbon dioxide to be given off as a gas. This gaseous carbon dioxide is transported to a storage chamber through a conduit surrounded by cooling coils. The silicone oils are then recirculated by a pump through a conduit surrounded by cooling coils where the temperature of the silicone oils is again brought back to ambient or lower temperature before it again passes through the absorption chamber where the mixture of the silicone oils and carbon dioxide takes place.
