Pilot plant studies of CO/sub 2/ absorption by DEA at high CO/sub 2/ partial pressures
The removal of carbon dioxide from natural gas is a frequently encountered gas conditioning process. Absorption of CO/sub 2/ by an aqueous amine solution is one of the most common methods for CO/sub 2/ removal. In the past total acid gas (CO/sub 2/ + H/sub 2/S) usually accounted for less than 30% of the gas from the producing well. With the use of CO/sub 2/ miscible flooding for enhanced oil recovery and gas from ultra deep wells, the acid gas contant may easily exceed 80%. There is a lack of operating data in the literature for such high CO/sub 2/ concentrations. The goal was to determine the effects of CO/sub 2/ partial pressure (% CO/sub 2/ in the feed gas) on the rich DEA loading and on the overall mass transfer coefficient. The authors chose DEA because of its less corrosive nature; its resistance to degradation by COS and CS/sub 2/; its lower vaporization losses, and its low solubility for liquid hydrocarbons. The availability of this operating data can hopefully be used to develop correlations which can be used to design new adsorption plants or more accurately predict the performance of existing units.
