Abstract

Abstract Mineral carbonation is a realistic route for capture and storage of carbon dioxide. The principal advantages of this approach are the chemical stability and storage safety of mineral carbonates, the opportunities for process integration available, and the potential for conversion of low‐value materials into useful products. In this work, the valorization of alkaline waste materials from thermal processes by mineral carbonation utilizing intensified and integrated mineral carbonation routes is explored. Process intensification aims at providing the paradigm‐shifting techniques needed to revolutionize the chemical engineering industry in the twenty‐first century, particularly focusing on improvements toward process efficiency, yield, and sustainability. The combination of process intensification and process integration strategies has the potential to produce economically feasible and industrially acceptable carbonation technologies that can soon be implemented large scale, several examples of which are already proven at laboratory scale and are herein discussed. © 2011 Society of Chemical Industry and John Wiley & Sons, Ltd

Recomputing p-values needs the paper’s full text.

Claims the paper makes

We couldn’t retrieve this paper’s full text, so its claims and self-check weren’t run. The registry and citation checks still apply.

Claims other papers make about this one

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • The particle size is a key parameter affecting carbonation because reducing size increases surface area and consequently the availability of reactive Mg and Ca.

    “The particle size is a key parameter affecting carbonation because the reduction of size increases surface area and consequently the availability of reactive Mg and Ca.65”
  • The liquid/solid (L/S) ratio is an important parameter because carbonation requires specific L/S ratios to be efficient.

    “The liquid/solid (L/S) ratio is an important parameter because carbonation requires specific L/S ratios to be efficient.65”
  • Temperature influences both the dissolution of CO2 in water (dissolution decreases with temperature) and dissolution of calcium and magnesium from minerals (dissolution increases when temperature increases).

    “Temperature influences both the dissolution of CO 2 in water (dissolution decreases with temperature) and dissolution of calcium and magnesium from the minerals (dissolution increases when temperature increases).”
  • Low temperatures enhance the diffusion of CO2 in the carbonated shell, while high temperatures increase the magnesium and calcium available.

    “Low temperatures enhance the diffusion of CO 2 in the carbonated shell, while high temperatures increase the magnesium and calcium available.65,67”
  • Stirring or sonication during carbonation limits the formation of carbonate shells, allowing further dissolution of Mg and Ca and diffusion of CO2.

    “Stirring or sonication during carbonation limits the formation of carbonate shells, allowing further dissolution of Mg and Ca and diffusion of CO 2 .65”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
