Abstract

Gas Processors Association (GPA) initiated Project 992 to study the impact of sulfur species on glycol dehydration. This project is first systematic attempt to provide reliable thermodynamic data related to systems involving aqueous glycol solutions, CO2, and sulfur species. Two research reports have already been published: RR-183 (Davis et al. 2002) on solubility of CO2 and (CO2 + CH4) in MEG and TEG aqueous solutions and RR-189 (Marriott et al. 2005) on solubility of H2S and (H2S + CH4) in MEG and TEG aqueous solutions.

This report presents solubility data of COS and H2S in MEG and TEG aqueous solutions at VLE conditions. A total of more than 100 solubility measurements are presented for this challenging system in this report including about 30 data points for the systems involving MEG and about 65 for systems involving TEG. The solubility measurements generated by Project 992 will be utilized to refine the equation of state predictions for the solubility of H2S, CO2, and COS in glycol solutions and thus improve the modeling of all glycol dehydration systems handling sour gas components.
