low boiling point volatile solvent float roof storage tank

Flash Point - an overview | ScienceDirect TopicsThe majority of solvent cleaning work is performed in equipment of two types relative to flash point, either an open tank or a closed tank.. An open tank would typically be used for cleaning at less than the boiling point (cold cleaning). The potential for ignition of solvents in cold cleaning, under shipment, or storage conditions is assessed by measuring flash point in an open cup tester.
