PURPOSE: To reduce cost required for collecting PFC and environment load. CONSTITUTION: Gas comprising PFC is separated into PFC and other gas by a cooling mechanism trap 101 before it is diluted by nitrogen gas. A temporary storage mechanism 102 temporarily stores separated PFC to concentration by which efficient collection can be conducted and it is packed into a temporarily stored PFC cylinder.
