Filtration together with dry sorbent injection of activated carbon is widely used for VOCs removal in contaminated flue gas in incineration process. In addition, the sorbent acts as filter aids to the fabric media that enhance the efficiency of the filtration process. This study introduced a newly three in one formulated filter aids known as PrekotAC, which is a combination of PreKot™ and activated carbon. Similarly, a four in one filter aids known as TrikotAC, a combination of three materials PreKot™, activated carbon and lime is also introduced in this study. The adsorption of the formulated PrekotAC 10:90 and TrikotAC 10:5:85 on toluene was investigated in this study. The results showed that PrekotAC 10:90 was able to adsorbed more toluene compared to TrikotAC 10:5:85 . However, formulated filter aids TrikotAC 10:5:85 able to reduce the pressure drop across the filtration plant compared to PrekotAC 10:90 . The ability to reduce pressure drop in fabric filtration system means that the formulated material able to prolong the cleaning cycle of the filter plant which simultenously preserve the life span of the filter bag.
