Abstract

Recent research has indicated the potential for emissions of volatile organic compounds (VOCs) from industrial process drains, and a need for better understanding of the mass transfer kinetics associated with such emissions. In this study, a two‐zone model was developed in an effort to isolate individual mass transfer mechanisms. Zone 1, described in this paper, consists of the underlying channel in either a sealed or unsealed drain. A series of nine experiments we re completed on a laboratory drain system over a range of operating conditions to determine mass transfer parameters. Liquid‐phase mass transfer coefficients we re highly correlated with liquid flow rate for both sealed and unsealed drains. Gas‐phase mass transfer coefficients were less predictable, but were relatively constant.
