Abstract

Abstract: Oxy-fuel combustion is one of the mainstream techniques of large-scale commercial CO₂ capture. In order to intensively study the performance of CO₂ capture, also the capability of the integrated desulfurization and denitrification in the compression process during oxy-fuel combustion, the liquid carbon dioxide is used to wash the mixed gas on the 50 kg/h test stand and related parameters are adjusted. It is showed that NO_x, SO_x and other pollutants can be removed in the compression process simultaneously. Furthermore, the test on the effect of liquid-gas ratio on NO_x and SO_x removal efficiencies is conducted. The results show that the total NO_x and SO_x removal efficiencies are both up to more than 98% with SO₂ contents less than 50×10^-6 and NO_x contents less than 30×10^-6 in the exhausted flue gas. The study concludes that the compression and purification process has the potential to achieve the integrated desulfurization and denitrification.

Key words: coal-fired power generation, oxyfuel combustion, compression and purification, desulfurization and denitrification, carbon dioxide, pollutant control
