Oxy-fuel combustion has been shown to be an attractive technology to be implemented in cement production with CO₂ capture from a process point of view. Due to the market situations and future perspectives it is necessary that the technology can be retrofitted into existing plants. As part of the H20...

Oxy-fuel conditions may have a considerable influence on the cement production process. This paper presents the results of a first validation work aiming to model the combustion behavior under rich CO₂ conditions. The experiments took place in a 500 kWth pulverized fuel combustion rig. A swirl burne...

Aluminum production contributes to global CO₂ emissions both due to the production process itself and due to the generation of electric power required for aluminum production. A concept is presented for increasing the CO₂ concentration in the aluminum exhaust from ∼1% to ∼5% through the feeding of a...

Aluminium smelting plants typically emit 1.5 tonne of CO₂ per tonne of aluminium produced. However, the CO₂ concentration in the exhaust is very low, typically below 1%, since large quantities of air are employed for cooling of the electrolytic cells and for cooling of the raw gas before gas treatme...
