The mass transport for a liquid/liquid extraction system is examined using a numerical concept following the idea of the interface‐tracking method. Separate, body‐fitted, static computational domains are arranged around an imported steady‐state interface topology. The domains are coupled at the free interface to capture the behaviour of the conjugated system. The steady‐state hydrodynamics are the basis for the simulation of the transient mass transport, which is calculated as a passive scalar concentration or one‐way coupling. The investigation is restricted to the extraction from the disperse to the continuous phase. Simulation results for an extraction from the disperse to the continuous phase show that most of the mass is transferred through the wall‐film region into the continuous phase.
