Use of limestone for SO2 removal from flue gas in the semidry FGD process with a powder-particle spouted bed

Sulfur Removal in Bio-Briquette Combustion Using Seashell Waste Adsorbent at Low Temperature

“…As is the case in coal combustion, it is necessary to adsorb and control SO x emission during co-combustion. Many kinds of adsorbents have been adopted in the past, particularly calcium-based adsorbents [12][13][14][15][16][17][18][19][20][21][22][23][24][25]. The first generation of calciumbased scrubbers (a type of FGD) was made in Great Britain in 1920.…”

“…Limestone (in the form of CaO and Ca(OH) 2 in some cases) is commonly added as adsorbent to coal and coal/co-fuel blend combustions, both for pulverized and briquetted coal [19][20][21][22][23][24][25]. There is also a combined adsorbent of Ca(OH) 2 /fly ash [21].…”

Desulfurization of Flue Gas: SO2 Absorption by an Ionic Liquid

“…A variety of processes for SO 2 control, such as wet FGD, dry FGD, and semidry FGD processes, have been commercially widely adopted. [1] However, these methods require a large amount of water and further treatment of the resultant wastewater is also needed, or they produce by-products such as calcium sulfate. Recently, dry and catalytic methods for SO 2 removal have attracted much interest due to their economic benefits, [2] and copper on alumina (CuO/Al 2 O 3 ) catalyst sorbent is usually used.…”

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

“…Also the optimum performance of this system is investigated by studying the effects of different parameters such as bed height, molar ratio of sorbent to acid gas (Ca/S) and inlet concentration of SO 2 . bed and then collected by a bag filter (Moeini and Hatamipour, 2008).Several experimental investigations have been reported on this kind of reactor (Ma et al, 2001(Ma et al, , 1999(Ma et al, , 2000Liu and Kato, 2000;Xu et al, 2000) and the results confirm that PPSB has the advantage of higher SO 2 capture efficiency over the conventional existing processes.Mathematical modeling as an attractive and capable technique for performance analysis, scale up and optimization of the PPSB has been considered and employed by several investigators. The first model for this process was developed by Liu and Kato (2000).…”
