Fossil fuel e.g. coal, combustion performing method for e.g. refinery kiln, involves liquefying part of treated fumes by compression and cooling, and compressing liquefied fumes by using multiphase pump for obtaining compressed flux

摘要

The method involves mixing an oxygen rich flux with a carbon dioxide rich flux for forming a mixture, and burning a fuel e.g. petrol, with the mixture. Combustion fumes are treated for condensing water and driving out sulfur compounds. A part of the treated fumes is liquefied by compression of the fumes at a pressure comprised between 50 and 70 bars and by cooling of the compressed fumes at a temperature comprised between 0 and 40 degrees. The partially liquefied fumes are compressed, by using a multiphase pump e.g. helicon-axial dynamic pump, for obtaining a compressed flux.
