Mass Transfer Flux of CO2 into Methyldiethanolamine Solution in a Reactive‐Absorption Process

The mass transfer parameters of both gas and liquid phases affect the mass transfer flux of CO2 in absorption processes. In this study, an accurate correlation is proposed to calculate the CO2 mass transfer flux in an absorption‐reactive process by methyldiethanolamine (MDEA) solution using the Buckingham π theorem. The various parameters include film parameter, CO2 loading, concentration ratio, partial‐to‐total pressure ratio, film thickness ratio, and diffusion ratio which are incorporated in the model. An average absolute relative error of 4.4 % for the calculation of mass transfer flux was stated. An innovative correlation is proposed based on the Buckingham π theorem for prediction of CO2 mass transfer flux in the reactive‐absorption process using methyldiethanolamine solution. Effects of various parameters such as film parameter, CO2 loading, concentration ratio, ratio of partial pressure to total pressure, film thickness ratio, and diffusion ratio are considered in this model.
