Abstract

We present liquid vapor equilibria data and Henry's law con¬stants for Methyl-ethyl Ketone, Toluene, Butyl Acetate, Acetone and i-Propanol in surfactants: Octylphenyl Decaethoxylate, Sorbi-tan Monooleate and Sodium Sulfonate at temperatures of 20 to 70 C.

The objective of this study is to determine the effect of applying surfactant absorption technique (neat surfactants) to volatile organic compounds (VOC's) for the removal of these species as organic vapors from air emission streams.

Liquid/vapor equilibrium data are presented as curves in sever¬al different ways:

i. Each individual VOC at four temperatures between 22 C to 70 C in the respective surfactants Octylpenyl Decaethoxylate, Sorbitan Monooleate and Sodium Sulfonate. Liquid phase concentration ranges vary for 0.05 to 0.45 mole fraction.

ii. ii. Vapor/liquid concentrations for all the 5 organics in the respective surfactants. At the individual temperatures : 22 C, 40 C, 60 C and 70 C. Liquid phase concentration ranges vary for 0.05 to 0.45 mole fraction.

iii. Vapor/liquid equilibria data for each organic at the four respective temperatures in all surfactants (the different absorption capacity of each surfactant).

Vapor concentration data was determined through use of gas chromatography. Analyses of vapor samples over the liquid at the equilibrium was achieved.

All the surfactants provided significant absorbent capacity for the VOC's efficient except for Acetone.

This study determined that the application of pure surfactant scrubbing to absorb the organic vapor is very promising.
