Abstract

Oxy-combustion technology is a zero-emission technology with great potential for commercial use in the nearfuture. Application of this technology is linked with high energy losses in oxygen production and preparation ofcaptured CO2 for transport to a storage place. In the analyzed oxy-combustion power plant with cryogenic airseparation unit the compression of gases is responsible for most of the energy consumption. Compressed gasesare sources of significant amounts of waste heat energy. Effective use of this energy is crucial to reducing theefficiency drop caused by additional installations. One method extensively examined in the literature for effectiveutilization of medium-grade and low-grade waste heat energy is the application of the Organic Rankine Cycle(ORC), which uses a low-boiling medium to produce additional electric power. The paper presents the results ofanalyses of the use of heat recovered from three sources identified in the oxy-combustion unit to power the ORCmodule. This includes heat from gases in the compression installations within the air separation unit, the CO2processing unit and the CO2 compression installation. Thermodynamic and economic analyses were performedto assess the potential investment.
