Title:
POWER PLANT WITH CO2 CAPTURE AND COMPRESSION
Document Type and Number:
WIPO Patent Application WO/2009/087210
Kind Code:
A3
Abstract:
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 plants frequency response 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 provide a power reserve for under- frequency events without deloading the plant (1 ) to part load. This is 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 (1 ). Besides the method a plant (1 ) designed to operate according to this method is subject of the present invention.
