Hybrid processes have received more attention in pollutant removal due to the combination of advantages of each process. A membrane combined with absorption was developed and studied for the removal of volatile organic compounds (VOCs) from lab to industrial scale. The ionic liquid membrane containing 1‐butyl‐3‐methylimidazolium bis(trifluoromethyl sulfonyl)imide ([Bmim][NTf 2 ]) showed competitive absorption on toluene. An industrial‐length ionic liquid membrane was investigated under optimized conditions based on lab‐scale results for a long time. The arrangement of the membrane modules was also evaluated, including connection in series and parallel. As a result, the proposed ionic liquid membrane is highly promising for industrial applications.
