For floating roof tanks,multiple shunt connections at 1.5-m intervals around the roof perimeter are recommended (Bouquegneau,2007).Interestingly,in some cases tank shunts have been found to actually increase the risk of fires during lightning storms,as they are a source of sparking when hit by lightning (LEC,2006).TITLE V PERMIT APPLICATION STORAGE TANKS15.For Internal Floating Roof tanks A.Rim Seal system description _____ Liquid Mounted Primary _____ Liquid Mounted Primary plus Secondary SealStorage tanks,Fixed-roof tanks,Floating roof tanks ProductsCharacteristicsIndustryTypesAdvantagesOther usesConstructionFutureVersionsEquipmentFunctionSummaryOperationExamplesStorage tanks containing organic liquids,non organic liquids,vapors and can be found in many industries.Most storage tanks are designed and built to the American Petroleum Institute API-650 specification.See more on wermacUSERS GUIDE to TANKS - United States Environmental (7) You may only use the Vapor Weight Speciation option for Horizontal Fixed Roof Tanks and Vertical Fixed Roof Tanks.If you enter 100 percent of the vapor component information for a tank using this speciation option,individual compound emissions will be calculated using the
