Based on the diffusion equation of multivariate mass transfer, the method of estimating the multivariate mass transfer coefficient of gas-liquid mass transfer process with chemical reaction and adsorption on the enhanced factors of gas-liquid mass transfer and gas-liquid mass transfer accompanied by chemical reaction and adsorption was proposed. The non-equilibrium model and the mass transfer coefficient obtained from the above method are used to simulate the process of fatty acid methyl esterification reaction, which is consistent with the experimental results.
