Method for producing cement with separation of CO2
A plant for producing cement clinker from calcium carbonate-containing raw meal. A preheating stage preheats the raw meal, which preheating stage is heated by exhaust gases from a following sintering stage. A stage is provided for deacidification and sintering of the raw meal. A cooling stage for the sintered meal is of at least two-stage design and has a gas separation stage for separating exhaust gases from the deacidification and sintering stage which is routed in a first gas circuit from the cement clinker cooling gas. A gas/gas heat exchanger is arranged downstream of the preheating stage in the gas flow direction, through which heat exchanger heat from the combined exhaust gases which leave the preheating stage is transferred into a gas, extracted from the gas for cooling the cement clinker, routed in a second gas circuit, for drying the raw meal in a preceding grinding stage.
