Abstract
A method/system for sequestering carbon dioxide from cement and lime production facilities wherein carbon dioxide from flue gases originating from cement or lime production facilities is recovered and transported to a building materials production facility where it is sequestered.
Claims24
A method of sequestering carbon dioxide from cement and lime production facilities comprising
- i) treating flue gas produced at the cement and/or lime production facility to render the carbon dioxide transportable, wherein the amount of flue gas treated is 1-8% of the total flue gas produced at the cement and/or lime production facility;
- ii) transporting the carbon dioxide to a building materials production facility;
- and
- iii) performing at least one operation of
- (a) treating one or more building materials with the carbon dioxide in such a manner as to permanently sequester the carbon dioxide in the building material;
- (b) treating a process water produced in the building materials facility with the carbon dioxide to lower a pH of the process water, or
- (c) treating concrete or a concrete component at the building materials production facility to cool the concrete or component.

A method of sequestering carbon dioxide from cement and lime production facilities comprising
- i) treating flue gas comprising carbon dioxide from the cement or lime manufacturing process to render the carbon dioxide transportable, wherein the amount of flue gas treated is 1-8% of the total flue gas produced at the cement and/or lime production facility;
- ii) transporting the carbon dioxide to a precast concrete production facility;
- and
- iii) treating a precast object comprising a cement binder with the carbon dioxide, wherein the treatment with carbon dioxide occurs upstream of a curing operation.
