USE OF CARBON DIOXIDE GENERATED IN MANUFACTURING SYNTHETIC HYDROCARBON CHAINS

摘要

The invention relates to the use of a carbon dioxide stream generated in oxygen gasification of organic matter for carbonating calcium from a liquid containing calcium ions. The invention also relates to a manufacturing process of paper or board, wherein organic matter is gasified with oxygen in order to carbonate the calcium, the produced carbon dioxide stream is reacted with a liquid containing calcium ions and the carbonated calcium is added to the pulp during the papermaking process as a filler or onto finished paper as a coating.
