Equipment for permanently storing ardealite

The present application relates to an apparatus for permanently storing ardealite. The present invention relates to an apparatus for producing materials for permanently depositing ardealite and simultaneously permanently sequestering carbon dioxide, comprising: a decomposition reactor (10) adapted to decompose said calcium sulfate contained in ardealite with hydrogen into calcium oxide, sulfur dioxide and water, whereby the gas stream contains sulfur dioxide and water and the solid stream contains the resulting calcium oxide product; a sulfuric acid production unit (50) adapted to convert sulfur dioxide contained in the gas stream obtained from the decomposition reactor (10) into sulfuric acid; a carbonation reactor (20) adapted to carbonize calcium oxide contained in the solid stream with carbon dioxide to calcium carbonate in a temperature range of 500-800 DEG C to obtain permanently deposited solid material wherein the decomposition reactor (10) is connected by one or more lines to the sulfuric acid produc
