Power plant for co2 capture

Abstract

Since CO2 is identified as a main greenhouse gas, its capture and storage is essential to control global warming. Competitiveness of power plants designed for CO2 capture and compression, retrofit ready power plants and efficient ways to retrofit conventional power plants to CO2 capture plants will allow earlier utilization of CO2 capture systems (12). The objective of the present invention is to provide a fossil fired power plant with minimum impact of the CO2 capture system (12) on the conventional part of the plant as well as a method to operate such a plant. Further, a power plant, which is ready for the retrofit of a CO2 capture plant and a method of retrofitting an existing plant into a power plant with CO2 capture as well as a method to operate this kind of plant are the object of the invention.; One main aspect of the invention is to add a power plant part, which is capable of providing the steam and power required to operate CO2 capture system (12), and to provide a CO2 capture system (12), which has the capacity to remove CO2 from the flue gas flows of the conventional, and of the additional power plant part.

Description

technical field [0001] The present invention relates to CO with integrated 2 Captured power plants and CO 2 capture ready (CO 2 capture ready) power generation equipment. Background technique [0002] In recent years, the production of greenhouse gases has obviously led to global warming, and further increases in the production of greenhouse gases will exacerbate global warming. Due to CO 2 (Carbon dioxide) is considered to be the main greenhouse gas, and carbon capture and storage is considered as a possible main method to reduce the release of greenhouse gases into the atmosphere and control global warming. This application will CO 2 The capture, compression, transport and storage process is called CCS. CO removal from flue gas after combustion of carbon-based fuels 2 Or the process of removing and treating the carbon before burning it is called capture. Regeneration of any absorbent, sorbent, or other removal of carbonaceous CO from flue gas or combustible gas st...

Problems solved by technology

[0008] The purpose of these methods is to reduce the specific CO 2 Power requirements for capture equipment, however they add to the complexity of the equipment and its operation

Furthermore, complex integration schemes make it difficult to integrate CO 2 Conversion of capture plants to existing power plants or power plant concepts
