ABSTRACT:
Floating roof storage tanks are modified to include a foam surge tank, a low-pressure blower and a foam generator for generating vapor-suppressing foam during withdrawal of liquid from the storage tank and after the floating roof reaches its lowest elevation in the storage tank so that the tank space previously occupied by volatile liquid is provided with a vapor-suppressing foam blanket during liquid withdrawal and refill. The surge tank is mounted directly on the floating roof and discharges its foam through an opening in the roof into the tank storage space. During liquid refill the foam may be forced out through a vent conduit onto the roof of the tank and dissolved and recovered.
