Gas treating with formulated amine mixtures: Optimization through modeling and simulation
- Dow Chemical U.S.A., Freeport, TX (US)
With rapidly increasing use of specialty formulations in the gas processing industry, it has become necessary to understand the underlying physical and chemical phenomena in order to predict the effect of design and operating variables on the process performance. Accordingly, the VLE, reaction kinetics, and mass transfer models for amine formulations have been developed and incorporated in an overall absorber simulator, which does rigorous tray-by-tray calculations using a rate approach. This paper presents the optimization of a typical gas treating plant through a case history. The quantitative effects of changing gas composition, capacity, circulation rates, and solvent formulations on the overall absorber performance are illustrated. The use of simulation to determine the best solvent formulation for a given set of operating conditions and plant requirements is demonstrated.
