Increasingly high demands are being placed on new separation technologies due to stricter product quality requirements, environmental legislation, energy efficiency demands, and the need to reduce costs [1]. To meet these increasing demands, there is a tendency to combine processes into hybrids. In a membrane contactor, separation is fully integrated-with an extraction with stripping or an emulsion liquid membrane (ELM) operation with hollow fiber (HF) contactor or absorption process-into one piece of equipment. This allows the advantages of both processes to be fully exploited [2].
