Abstract
Absorption is one of the unit operations which is widely used in the oil and gas gas industries. The reproduction of the operating conditions of any plant, in particular, of a natural gas processing unit is, very important because modifications and procedures of optimization can be accomplished to increase the performance and the flexibility of the process and to maintain the economic competitiveness. In the present study, a robust and simple predictive tool is developed for rapid estimation of absorption efficiency as a function of absorption factor and number of absorber stages. Predicted results are compared with the reliable data and shows excellent agreement. The average absolute deviation between the experimental data and the proposed correlation was found to be around 1 %. Results indicate that the proposed method appears to be superior owing to its accuracy and clear numerical background, wherein the relevant coefficients can be retuned quickly if new data are available in the future. The predictive tool proposed in the present work is novel and unique expression which is non-existent in the literature. This is expected to benefit the oil and gas industries in making design amendments leading to informed decisions for the prediction of absorption/stripping efficiency for a given application in oil and gas processing industries.
