Abstract: A gas processing apparatus using a hybrid composite file is provided to prevent VOCs(volatile organic compounds) gases from leaking when a vehicle is filled with gasoline using an enclosure-type nozzle, thereby preventing air pollution. A gas processing apparatus(200) using a hybrid composite file comprises the following units. An enclosure-type nozzle(100) is installed in a filling gun(2) of a filling apparatus(1). A separating film module(220) collects VOCs gases of sucked gasoline through a suction unit selectively. A low-temperature condensation unit(230) condenses VOCs gases at a low temperature in order for the VOCs to become a liquid and discharges the VOCs.
