Sour compression process for the removal of SO and NO from oxyfuel-derived CO2

Kinetic study of the nitric oxide oxidation between 288 and 323 K, under pressure, focus on the oxygen influence on the reaction rate constant

“…They came to the conclusion that at high pressure the reverse reaction of NO oxidation has an impact on the reaction rate. Murciano et al 36 observed better NO oxidation to NO 2 when the total pressure increases from 0.5 to 1.5 MPa and the nitric oxide partial pressure increases from 1.6 × 10 −4 to 4.7 × 10 −4 MPa. Ting et al 37 obtained the same global reaction kinetics typically used at atmospheric total pressures; they did not found any influence of the total pressure on the reaction rate or the rate constant k 1 .…”

Mapping the Cu-BTC metal–organic framework (HKUST-1) stability envelope in the presence of water vapour for CO2 adsorption from flue gases

“…Emitted at 50-75°C and 0-1 barG [1], flue gases contain large amounts of CO 2 , as much as 5-15 vol.%, together with other gases such as nitrogen (70-75 vol.%) and water vapour (5-7 vol.%), depending on the fuel being used [1,2]. Novel combustion technologies, such as oxyfuel combustion can provide flue gas streams with over 99 vol.% CO 2 concentration, facilitating the CO 2 capture [3]. However, the target concentration of CO 2 in the exhaust clean gas to be released into the atmosphere is only 0.03 vol.% [4].…”

Effect of operating pressure and fuel moisture on net plant efficiency of a staged, pressurized oxy-combustion power plant

“…It is important to note, however, that the material of construction only forms a small part of the boiler cost, which is mainly governed by boiler tube costs. The effect of pressure on the design of the DCC is not obvious, though there is potential for size reduction with increasing pressure, both due to the potential increase in performance of the integrated pollutant removal reactions at higher pressure (White et al, 2013;Murciano et al, 2011;Ajdari et al, 2014) and reduced gas volumes.…”
