This article presents experimental and modelling studies on the absorption of NH 3 into water in a rotor‐stator reactor (RSR). The influences of operating parameters such as the rotation speed of rotor, liquid flow rate, and gas flow rate on the overall volumetric mass transfer coefficient (K y a) of NH 3 were investigated. It was found that K y a increased with an increasing rotation speed, liquid flow rate, and gas flow rate. A correlation to predict the K y a of NH 3 in the RSR was established and found to be in agreement with the experimental data with deviations within 10 %. A comparison was made between the K y a of NH 3 in the RSR and RPB, and the result showed that K y a of NH 3 in the RSR was 13 % higher than that in the RPB, thus signifying that the RSR has better intensification effect for mass transfer limited processes than the RPB.
