Abstract

Solubility data for CO2 in monoethylene glycol (MEG) are limited in the open literature with most of the data limited to temperatures above 298.15 K through a small number of sources. This work focused on the solubility of CO2 in pure MEG in a wider range of temperatures and pressures as experimental data in such conditions are extremely limited in the open literature. These results can be used to optimize EoS and increase prediction reliability due to the wider range. The solubility of CO2 in MEG was measured between 263.15-343.15 K and 0.2-40.3 MPa. The experimental results from this study are compared to available data from the open literature together with the CPA-SRK72 calculations. The data from this work together and open literature were used to calculate a binary interaction parameter (BIP) of 0.053 between 263.15-398.15 K to correlate the experimental data. The experimental results showed an overall absolute average deviation of 4.81% from the calculated modeling results.
