Abstract:

 Based on conventional mass transfer models developed for oxygen, the use of the non linear ASCE method, 2-point method, and one parameter linear-regression method were evaluated for carbon dioxide stripping data. For values of < approximately 1.5/hr, the 2-Point or ASCE method are a good fit to experimental data, but the fit breaks down at higher values of . How to correct for gas phase enrichment remains to be determined. The one-parameter linear regression model was used to vary theover the test, but it did not result in a better fit to the experimental data when compared to the ASCE or fixed assumptions.
