Determination of distribution coefficients of volatile sulfur-containing compounds among aqueous solutions and gas phase by continuous gas extraction

Activity Coefficients at Infinite Dilution of Alkanols in the Ionic Liquids 1-Butyl-3-methylimidazolium Hexafluorophosphate, 1-Butyl-3-methylimidazolium Methyl Sulfate, and 1-Hexyl-3-methylimidazolium Bis(trifluoromethylsulfonyl) Amide Using the Dilutor Technique

“…This kind of equipment was already described previously. 23 It is very similar to the arrangement designed and employed by Krummen et al 13,20 An exactly known amount (of about 3 cm 3 ) of the solvent (i.e., the ionic liquid) is filled into the glass-made saturation cell (S), which has a total volume of 5 cm 3 . The saturation cell is immersed in a water thermostat (WT; model U-10, VEB Pru ¨fgera ¨tewerk Medingen, former GDR) with a maximum variance of ( 0.1 K. Since the ionic liquid is nonvolatile at any experimental conditions, an additional presaturation cell 13 that saturates the carrier gas with the solvent, as it is indispensable for volatile solvents, is not needed.…”

Study of the Mass Transfer–Biodegradation Kinetics in a Pilot-Scale Biotrickling Filter for the Removal of H2S

“…All the operating conditions and other model parameter values are listed in Table . The Henry’s constant ( H ) of H 2 S is 0.47 at the gas–biofilm interface . All the CFD simulations were performed on a 3.3 GHz Intel 1 CPU (10 cores) with 128 GB of RAM.…”

(Vapour+liquid) equilibria, (VLE) excess molar enthalpies and infinite dilution activity coefficients of selected binary systems involving n-hexyl pyridinium bis(trifluoromethylsulphonyl)imide ionic liquid: Experimental and predictions using modified UNIFAC (Dortmund)

“…The apparatus and the experimental procedure were described in detail in previous studies [18]. The method is alternatively called the dilutor technique, as well as continuous gas extraction technique [19]. The ionic liquid being non-volatile, there was no need for a pre-saturator cell.…”
