Adsorption–Desorption of Surfactant for Enhanced Oil Recovery

Surfactant loss due to adsorption on the porous medium of an oil reservoir is a major concern in enhanced oil recovery. Surfactant loss due to adsorption on the reservoir rock weakens the effectiveness of the injected surfactant in reducing oil–water interfacial tension (IFT) and making the process uneconomical. In this study, surfactant concentrations in the effluent of the corefloods and

Adsorption, Absorption and Desorption What's the

Adsorption and desorption are the main processes operating in chromatography. It is the relative rates of adsorption and desorption onto and off the stationary phase that allows chemicals in samples to be separated. If the column conditions favour adsorption of a molecule, then the molecule will adhere to the stationary phase and be separated
