Detailed modelling of a flue-gas desulfurisation plant

A rate equation for Ca(OH)2 and CO2 reaction in a spouted bed reactor at low gas concentrations

“…The carbonation reaction of hydrated lime with CO 2 has been studied for many applications such as the CO 2 separation from flue gas or from syngas, the storage of energy, chemical heat pump, and the clean hydrogen production by reaction integrated coal gasification (Gomez et al, 2007;Lee, 2004;Kojima et al, 1989). The study of reaction kinetics of CO 2 with different absorbents is of importance for the above mentioned processes.…”

“…Lack of capture/sequestration strategy is one of the main factors which results in an increase in CO 2 emission. Recently, several technologies are developed or the existing technologies are being improved, which could help in reduction of CO 2 emissions (Gupta and Fan, 2002;Gomez et al, 2007;Al-Marzouqi et al, 2008). Fossil-fuel based power plants nowadays are experiencing a large number of CO 2 separation processes (Gupta and Fan, 2002).…”

Non-isothermal modeling of the flue gas desulphurization process using a semi-dry spouted bed reactor

“…Custom technologies for FGD can be classified into three different categories. Wet processes (wet lime/limestone scrubbers), semi-dry processes (spray dry scrubbers, duct sorbent injection) and dry processes (furnaces sorbent injection, varying adsorbent) (Gǐomez et al, 2007;Nygaard et al, 2004;Ma et al, 2001).…”

Research Progress of wet FGD process with waste marble

“…China's energy structure is dominated by coal, the SO 2 in the flue gas of thermal power plant is the main component of air pollution, which has the characteristics of high SO 2 concentration and large amount of flue gas, and is also the main material to form acid rain [1].Acid rain not only seriously corrodes buildings and public facilities, but also destroys large areas of forests and crops, so the removal of sulfur in the exhaust gas is a very important issue in flue gas treatment [2][3].…”
