摘要：A method for reducing the volume of gases released into the atmosphere during a test for detecting perforations in an underground fuel storage tank or a container for other chemical or volatile liquids using a method involving the reduction in the pressure in the ullage of the tank. The method involves the cooling of the evacuated gases as they are evacuated from the tank to condense a portion of the evacuated gases, thereby reducing the volume of the evacuated gases which is released to the atmosphere.
