Abstract
Official abstract text for this publication.
In one embodiment, a carbon dioxide separating and capturing apparatus includes an absorption tower to allow a gas containing carbon dioxide to contact with an absorption liquid and discharge a rich liquid, a regeneration tower to cause the absorption liquid to release a gas containing the carbon dioxide and discharge a lean liquid, and first and second regenerative heat exchangers to heat the rich liquid with the lean liquid. The first regenerative heat exchanger heats the rich liquid with the lean liquid from the second regenerative heat exchanger and discharges the rich liquid in a liquid phase, and the second regenerative heat exchanger heats the rich liquid in the liquid phase with the lean liquid from the regeneration tower. The lean liquid from the first regenerative heat exchanger and the rich liquid from the second regenerative heat exchanger are fed to the absorption and regeneration towers, respectively.
First claim
Opening claim text (preview).
The invention claimed is: 1. A carbon dioxide separating and capturing apparatus comprising: an absorption tower to which a gas containing carbon dioxide is introduced, the absorption tower being configured to allow the gas to contact with an absorption liquid for absorbing the carbon dioxide, and to discharge a rich liquid which is the absorption liquid having absorbed the carbon dioxide; a regeneration tower configured to heat the absorption liquid to cause the absorption liqu…
