摘要

The procedure and device for the separation of carbon dioxide from exhaust gas of plant that burns fuels such as natural gas, petroleum, coal and biomass with burned chalk, comprise carrying out calcination of limestone through heat that is brought over high temperature heat exchanger out of same process or through waste heat that is brought over high temperature process. The heat released during the adsorption is again used in the same process or bounded in the processes. The separation and the calcination are carried out in two crossover turbulence layers. The procedure and device for the separation of carbon dioxide from exhaust gas of plant that burns fuels such as natural gas, petroleum, coal and biomass with burned chalk, comprise carrying out calcination of limestone through heat that is brought over high temperature heat exchanger out of same process or through waste heat that is brought over high temperature process. The heat released during the adsorption is again used in the same process or bounded in the processes. The separation and the calcination are carried out in two crossover turbulence layers by which the flow of the bed materials inverts one of the turbulence layers and the inflow of the bed materials inverts other turbulence layer. The calcination is carried out in a high temperature heat exchanger in flying stream, while the carbon dioxide adsorption takes place through the turbulence layer in flue gas stream in suitable temperature zone between convection heat surfaces of steam generator.
