Abstract: In some aspects, a method of carbonation control can include monitoring, via a first sensor, an environmental condition in a contactor unit, the contactor unit including a plurality of carbonation vessels including carbonation medium, monitoring, via a second sensor, an environmental condition at a location outside of the contactor unit, predicting, based on the measured environmental condition in the contactor unit and the measured environmental condition at the location outside of the contactor unit, a local humidity in a carbonation vessel from the plurality of carbonation vessels, a water content of the carbonation medium in the carbonation vessel from the plurality of carbonation vessels, and a carbonation extent of the carbonation medium in the carbonation vessel from the plurality of carbonation vessels for a carbonation forecasting period, and executing an action on the plurality of carbonation vessels based on the predicted water content and predicted carbonation extent.

Abstract: Embodiments described herein relate to capturing and sequestering CO2 emissions from the cement production process with the potential to produce carbon-negative cement. Methods described herein can include contacting calcium oxide (CaO) with ambient air at a carbonation station to form a first stream of calcium carbonate, combining the first stream of calcium carbonate with a second stream of calcium carbonate in a calciner to form a combined stream of calcium carbonate, and applying heat to the calciner to decompose the combined stream of calcium carbonate into a stream of calcium oxide and a CO2 stream. The method further includes sequestering the CO2 stream, dividing the stream of calcium oxide into a first calcium oxide stream and a second calcium oxide stream, feeding the first stream of calcium oxide to the carbonation station, and feeding the second stream of calcium oxide to a kiln to produce a clinker.

Abstract: A plurality of carbonation plots are positioned in communication with atmospheric carbon dioxide to facilitate sequestration thereof via ambient weathering. The carbonation plots include a composition rich in metal oxides, which are positioned within the environment, such as on non-arable land, and exposed to the environment to react with carbon dioxide in the air and form metal carbonates. After about one year of exposure, the composition is recollected and calcined to produce a carbon dioxide stream and replenish the metal oxides, which can be redistributed in the carbonation plots to sequester additional carbon dioxide. The systems and methods of the present disclosure enable capture and redistribution of carbon dioxide for industrial-scale uses for very abundant quarry minerals and enable large-scale low-cost carbon capture projects for municipalities or corporations.
