The present invention relates to methods and systems for improving the utilization of energy in a cement manufacturing plant comprising an absorption based contaminant, e.g. CO, capture process using thermal regeneration of a liquid absorbent. The methods and systems of the present invention are characterized in that the thermal regeneration of the liquid absorbent is at least partially effected using a hot exhaust gas stream generated in the kiln of the cement manufacturing plant.

Heat integration of a cement manufacturing plant with an absorption based carbon dioxide capture process

A system and process for capturing COis disclosed. The processincludes reusing heat from a COcompression processby providing the heat to a fuel treatment process. The heat may used to dry a fossil fuel to improve the efficiency of the fossil fuel combustion.

Waste heat recovery from a carbon capture process

A system () for regenerating a rich absorbent solution (), the system including: an absorber () facilitating interaction between a process stream () and an absorbent solution, wherein the process stream comprises an acidic component, and interaction of the process stream with the absorbent solution produces a reduced acidic component stream () and a rich absorbent solution; at least one heat exchanger accepting at least one of said reduced acidic component stream and the process stream to transfer heat to a heat transfer fluid (); and at least one mechanism () to transfer the heat transfer fluid from said at least one heat exchanger to a regenerator () regenerating the rich absorbent solution, wherein each of the at least one mechanisms is fluidly coupled to each of the at least one heat exchangers.
