Abstract
EU regulations in the field of climate policy imposes strict limits on the emission of pollutants. In addition, there are ongoing work on systems to CO2 capture, which is considered a major cause of global warming on Earth.
During gas combustion emits significantly less pollution and carbon dioxide which ifs their advantage. However, because of the limited CO2 emission it is possible to introduce the uptake of said compound by chemical absorption, predisposed to be used for the coal-fired plants. Low concentrations of carbon dioxide in the exhaust gas can be increased by using exhaust gas recirculation system of a gas turbine, while reducing energy consumption during capture. In addition, the second topic discussed in the article relates to the use of hydrogen fuel for gas system. It has been shown that hydrogen admixture injection for natural gas affect considerable reduction emission carbon dioxide.
This article presents the change in the operating parameters of the combined cycle with installation of CO2 capture and exhaust gas recirculation. Built a mathematical model of the system using the code of Ebsilon Professional and performed parametric calculations. In the report, there was conducted an analysis of the dependence of the change of LHV of gaseous fuel which is a mixture of natural gas and hydrogen for proper work of the gas turbine installation.
The built model and obtained results are useful in the analysis of combined cycle systems integrated with separation of carbon dioxide from the flue gas.
