Resumo: Abstract This work aimed to produce zeolite membranes MCM-22 using two methods of synthesis, dip coating (DC) and vapor phase transport (VPT), to be evaluated in the oil/water emulsion separation process. The membranes were prepared at 150 °C for 10 days and characterized by X-ray diffraction and scanning electron microscopy. They were evaluated in tests of pure water permeation and oil/water emulsion separation system of a synthetic effluent, using a stainless-steel module under the conditions of the initial concentration of the emulsion of 100 mg/L, temperature of 25 °C and pressure of 2.0 bar. The results showed that the MCM-22 zeolite membrane by DC had the final value of the permeate concentration of 3.2 mg/L and the membrane prepared by VPT presented a final value of 3.9 mg/L which were within the standards required by Resolution No. 392 of CONAMA which is up to 20 mg/L of mineral oils.
