Low emission thermal plant

A thermal power station for carbonaceous fuel, comprising:

• a combustion chamber, where the fuel is burned under elevated pressure in the presence of oxygen;
• a gas pipe for leading an exhaust gas from the combustion chamber through cooling means into a contact device where the exhaust gas is brought into contact with an absorption agent in which mainly CO2 is absorbed and where the other gases in the exhaust gas, in the main, are not absorbed;
• a gas pipe for withdrawal of a not absorbed or CO2 depleted fraction, from the contact device;
• means to reheat the CO2 depleted fraction;
• means for expansion of the reheated CO2 depleted fraction before releasing the expanded CO2 depleted fraction into the surroundings;
• and
• means to transport the absorption agent with absorbed CO2 from the contact device to deposition or to means for regeneration of the absorption agent for re-circulation to the contact device,
• wherein the combustion chamber comprises means to provide steam and lines to lead the steam to steam turbines for expansion of the steam.
