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.

Ionic liquids (ILs) are promising alternative solvents for traditional organic compounds using selective separation. However, some environmental risks of ILs, resulting in a limitation of their applications in industry. In this work, the stability of ILs into multi-channel tubular ceramic membranes (ILM) provides a promising way to realize the use of ILs with environmental damages reducing. This novel process has been investigated for toluene removal from a toluene/air gas mixture based on 1-butyl-3-imidazolium bis(trifluoromethylsulfonyl)amide ([Bmim][NTf2]) as a liquid sorbent. In addition, the effects of operating conditions on toluene separation were studied and discussed by experiment and modeling. The absorption capacity of toluene by the ILM on proposed operating conditions was around 224.74 mg per gram of the ionic liquid. The support ceramic membrane can effectively prevent ILs leakage from causing secondary waste and ensure longtime operation. Regeneration of polluted ILM was available.

Membrane processes are promising methods to separate gases from feed streams without phase changing. A hybrid process, the combination of ionic liquids with a ceramic membrane (ILM), has been developed for humidity removal in a green continuous process. This new concept provides a more efficient and available ionic liquid (IL)-based membrane regeneration process, which just switches the moist feed stream to dry air. Furthermore, the ILM presents high stability and mechanical resistance during long-time operation. In addition, the influences of several operating parameters, including flow rate, temperature, absolute pressure, and feed concentration on process efficiency were investigated. The lower inlet flow rate was found to be favorable for drying humid air. Moreover, when the pressure increased, the mass of absorbed water was increased, while the feed concentration had no significant effects on the membrane separation performance. However, the operating temperature had a great effect on humidity removal. It is necessary to note that the processes at room temperature can limit the energy consumption. The absorbing process of ILM remained efficient after several absorption desorption cycles. Therefore, the new ILM hybrid process that has been developed has great potential for consecutive humidity removal processes.
