The addition of wetting agents such as polyether silicone oil

Compound No.3 and XHG-248 into desulfurization solutions to improve the performance of WFGD system for removal of fine particles was investigated in rotating-stream-tray scrubber with Na2CO3 as reagent.The influence of liquid-gas ratio and temperature of desulfurization solutions on role of wetting agents and the performance was studied

and the effect of heterogeneous condensation enlargement and addition wetting agents on fine particles removal efficiency was also examined.The results showed that temperature of desulfurization solutions has significant influence on performance of wetting agents

and the removal efficiency can be improved at normal temperature using anyone of wetting agents studied

but when the temperature of desulfurization solution rises to 45℃ only Compound No.3 is of efficiency.The removal efficiency can be significantly improved by simultaneously adding proper amount of steam between trays and wetting agent Compound No.3

increasing from about 20% to 65%.
