Desulfurization behavior of Ca-based absorbents …
11-10-2001 · The capture of H 2 S or SO 2 with Ca-based absorbents, limestone and dolomite, was investigated under a periodically changing condition between reducing and oxidizing atmospheres, taking account of the coexistence of these atmospheres in a fluidized-bed coal gasifier. The degree of desulfurization in the reducing atmosphere was large compared with that in the oxidizing atmosphere.
Desulfurization Performance and Kinetics of …
20-7-2020 · This desulfurization process has such advantages of lower capital cost, smaller site area, and no water consumption in comparison with other desulfurization processes. Moreover, the final desulfurization product, which is lignite char along with K 2 SO 4 , which can be used as either soil conditioner or fertilizer and avoids the cost of sorbent regeneration and loss.
Desulfurization of H2S using cobalt-containing …
1-3-2005 · Fig. 2 shows desulfurization performances of various absorbents flowing H 2 S. The normalized concentration represents the ratio of H 2 S concentration at the outlet to that of the inlet feed. Thus, the normalized concentration indicates the removal efficiency and the normalized time corresponds to the fractional conversion of cobalt oxide to the sulfide form of Co 9 S 8 .
Desulfurization performance of fly ash and CaCO3 …
1-1-2017 · To validate the desulfurization performance of the experimental setup, conventional calcium-based absorbent was selected for the experiment, and it is convenient to compare with other absorbents. Regarding industrial production, limestone and lime are usually applied for the wet flue gas desulfurization process.
Catalytic effect of Mn2+, Fe3+ and Mg2+ ions on ...
15-6-2020 · It is noteworthy that we only need to add a set of desulfurization equipment, without introducing other absorbents. It is known to all that wet flue gas desulfurization with limestone as the sorbent is one of the most widely used wet washing processes, due to its high desulfurization efficiency and low cost [9] , [10] , [11] .
Composite Solid Absorbent for Simultaneous …
The composite solid absorbent was developed for simultaneous desulfurization and denitrification of low-temperature flue gas. ... and phase compositions of fresh and used absorbents were measured to investigate the enhanced performance mechanism of absorbent and its removal mechanism for SO 2 …
Removal of sulfur dioxide using absorbent …
1-6-2005 · In order to elucidate the role O 2 and NO in the desulfurization reaction, the absorbent synthesized from coal fly ash and CaO was tested for its desulfurization activity in four series of experimental runs. Fig. 2 shows the breakthrough curves of the four experimental runs. The spent absorbents after the desulfurization activity were tested using FTIR analysis and the spectrum are …
