摘要
An apparatus comprises a separator, a compressor, a mixer and a pump. The separator operates on an input gas mixture comprising carbon dioxide gas and one or more other gases, providing a separated carbon dioxide gas output. A compressor compresses the separated carbon dioxide gas output, providing a second output comprising at least one of gaseous carbon dioxide and liquid carbon dioxide. A mixer mixes the second output with liquid water under pressure to provide a third output comprising: at least one of liquid carbon dioxide and gaseous carbon dioxide; and water with dissolved carbon dioxide. A pump pumps the third output into an underground structure such that components of the third output react with available rock surfaces to form stable carbonates.
