CO2 Capture and conversion pilot plant produces up to 2 tonnes of CO2 containing calcium carbonate product per day using raw flue gas with no concentration of CO2 needed.
Calera’s Pilot Plant located in Moss Landing, CA has now been in operation for approximately two years and the calcium carbonate produced from the capture and conversion of CO2 from the neighboring gas power plant has been used in a variety of demonstration and commercial projects.
The technology uses flue gas directly without the need to concentrate the CO2 and Calera has demonstrated the technology on CO2 from gas power plants and from coal burning. The flue gas containing CO2 is contacted in a scrubber with an aqueous alkalinity solution that effectively removes the CO2 and then contacted with a calcium source that results in the formation of the special calcium carbonate product that is then dried to a free flowing powder. This powder can then be used to make products such as board type products because of the special cementing nature of the calcium carbonate.
