Kj. Liekhus et Mj. Connolly, Estimation of volatile organic compounds (VOC) concentration within inner void volume of vented waste drums, WASTE MAN, 19(3), 1999, pp. 199-206
A test program has been conducted to demonstrate that the concentration of
volatile organic compounds (VOC)s within the innermost layer of confinement
in a vented waste drum can be estimated using a model incorporating diffus
ion and permeation transport principles as well as limited waste drum sampl
ing data. A. waste drum is assumed to contain a vented rigid polymer liner
that holds waste packaged in multiple layers of polymer bags. The model con
sists of a series of material balance equations describing steady-state VOC
transport from each distinct void volume in the drum. The primary model in
put is the measured drum headspace VOC concentration. Model parameters are
determined or estimated based on available process knowledge. This paper su
mmarizes the experimental measurements and model predictions of 13 VOCs in
three different drum configurations in vented waste drums. (C) 1999 Elsevie
