Complex exergy analysis of an integrated oxy-fuel combustion power plant with CO2 transport and storage
Abstract
The paper presents a method of the complex system exergy analysis, as well as an example of application in the case of an integrated oxy-fuel combustion (OFC) power plant with CO2 transport and storage. Complex exergy analysis consist of (a) local exergy losses, (b) cumulative exergy consumption, (c) cumulative exergy losses and (d) cumulative degree of thermodynamic perfection. The algorithms of the complex system exergy analysis are based on "input-output method" of the direct energy and material consumption. In the structure of the balance we distinguished main products (e.g. electricity), by-products (e.g. nitrogen) and external supplies (e.g. hard coal). The considered system (OFC power plant with CO2 transport and storage infrastructure) consists of seven interconnected modules, viz. boiler island, steam cycle, air separation unit, cooling water and water treatment module, flue gas quality control module, CO2 processing unit and CO2 transport and storage module, among which there also exist feedback relations.
