摘要： Since CO2 is identified as a main greenhouse gas, its capture and storage is essential to control of global warming. Flexible operation of CO2 capture and compression equipment will increase the competitiveness of power plants (1) designed for CO2 capture and compression and will allow earlier introduction of this kind of plants. The main objective of the present invention is to improve the plant operating characteristics by taking advantage of the additional flexibility, which can be realized by controlling the power consumption of the CO2 capture and compression system. One particular aim is to minimize the impact of CO2 capture and compression on the capacity of a power plant (1), i.e. to maximize the electric power the plant can deliver to the power grid. Further, the impact of CO2 capture and compression on the average plant efficiency shall be reduced. Both are achieved by an operating method, in which the power consumption of the CO2 capture system is used to control the net output (D) of the plant. Besides the method a power plant (1) designed to operate according to this method is subject of the present invention.

摘要： A method is provided for managing an amount of energy utilized by a carbon dioxide capture system. The method includes providing a fuel and a feed stream to a combustion system. The feed stream includes oxygen and a portion of a flue gas stream generated upon combustion of the fuel. The method also includes subjecting the flue gas stream to a carbon dioxide capture system to remove carbon dioxide therefrom, measuring a concentration of oxygen present in the feed stream, and selectively adjusting an amount of the flue gas stream included in the feed stream based on the measured concentration of oxygen in the feed stream. The selective adjustment is performed such that the feed stream maintains an oxygen concentration in a range of between about 10% to 90% by volume and the carbon dioxide capture system operates at an energy load between 1.4 GJ/ton of carbon dioxide and 3.0 GJ/ton of carbon dioxide.
