Approvisionnement en oxygène pour le captage du CO2 grâce à l'oxycombustion de charbon.

Oxygen supply for CO2 capture by oxyfuel coal combustion.

Numéro : pap. n. 085



The air separation unit (ASU) is one of the key parts of an oxycombustion power plant with CO2 capture and it is important that its design is optimised to give the right balance between power consumption, capital cost, flexibility and operability. To achieve the maximum benefit, this design optimisation should include not only the ASU, but also integration with the rest of the plant. In previous papers, Air Products has given details of the factors that need to be considered in the specification and design of an ASU, and how these influence the final design. In this paper, the authors summarise the results of these earlier studies and then go on to describe in more detail how the overall oxycombustion system can be optimised by integration of the ASU process with the rest of the system, and by designing the ASU with operating flexibility.
