Abstract
A calculation procedure to determine the influence of the silicone volume fraction on the physical absorption of VOCs in water/silicone oil mixtures is presented ( η silicone oil = 5 mPa s). It is based on the “equivalent absorption capacity” concept previously developed by Dumont et al. (2010) [1] and applied to a countercurrent gas–liquid absorber. The calculation procedure is first applied to three VOCs: dimethylsulphide (DMS), dimethyldisulphide (DMDS) and toluene, and then generalised to other VOCs. The influence of VOC partition coefficients ( H voc,water and H voc,solvent) and the ratio m R = H voc,water/ H voc,solvent is shown. For VOCs having a much higher affinity for silicone oil than for water ( m R > 20 as for DMDS and toluene), it is preferable to use pure silicone oil rather than water/silicone oil mixtures for absorption.
