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.

反应吸收过程中二氧化碳向甲基二乙醇胺溶液中的传质

气相和液相的传质参数都会影响吸收过程中CO ₂的传质通量。在这项研究中，提出了一种精确的相关性，以使用白金汉π定理，通过甲基二乙醇胺（MDEA）溶液计算吸收反应过程中的CO ₂传质通量。各种参数包括膜参数，CO ₂负载，浓度比，分压/总压比，膜厚度比和扩散比，这些参数已包含在模型中。计算出传质通量的平均绝对相对误差为4.4％。
