Abstract
The present invention discloses a carbon dioxide capture power generation system provided with a boiler to combust a fuel in the oxygen atmosphere, a carbon dioxide capture equipment to remove carbon dioxide in the wake flow of the boiler, a piping branching from the wake flow of the boiler to recycle the combustion exhaust gas to the boiler, and a desulfurization equipment to remove sulfur oxides and a sulfuric acid removal equipment to remove a sulfuric acid gas in the upstream of carbon dioxide capture equipment and in the wake flow of the boiler.
Claims11
A carbon dioxide capture power generation system comprising:
- a boiler to combust a fuel;
- a carbon dioxide capture device to remove carbon dioxide disposed downstream of the boiler;
- a dehydration device to remove moisture disposed upstream of said carbon dioxide capture device,
- a piping branching from downstream of the boiler to recycle an exhaust gas to the boiler;
- and
- a desulfurization device to remove sulfur oxides from said exhaust gas and a sulfuric acid removal device to remove a sulfuric acid gas which is different from said desulfurization device, both said desulfurization device and said sulfuric acid removal device being disposed upstream of said carbon dioxide capture device and said dehydration device and downstream of the boiler;
- wherein no dehydration devices are between said desulfurization device and said sulfuric acid removal device.
