CONCLUSION: Absorption performances of silicone oil towards toluene, DMS and DMDS were determined and showed that this solvent could be used during the first step of the process. The experimental design allowed equilibrium achievement within 30 - 60 minutes. Thus silicon oil gives a superior factor of 550 696. -Xylene removal using one- and two-phase partitioning biotrickling filters: steady/transient-state performance and microbial community International Journal of Environmental Science and Technology. In addition, it is also necessary to take measures to prevent moisture and air intrusion. In order to make silicone useful in aqueous systems, there are a variety of emulsions available. Silicon oil chemically known as polydimethysiloxane was found to be better absorbent for VOCs than water which quickly becomes saturated.
