The most common types are floating-roofs and fixed-roofs. Fixed roofs are permanently affixed to the top of the tank, which creates a great deal more space for vapors to accumulate when the tank is less than full. The less material in the tank, the more room for vapors to build up.
Choose Your Suitable crude oil storage tanks Types. In general, crude oil storage tank has two kinds, fixed roof tank and floating roof tank. Fixed roof tank is usually used when the quantity of crude oil is not too large. While, floating roof tank is the optimum selection for storing larger quantities of crude oil.Floating Oil Skimmers | Oil Skimmers of All Types - SKIMOILOur floating weir skimmers (FWS) originally designed as surface oil skimmers, simply drain an area from the top down and remove whatever is flowable on/from the waters surface.In the ash ponds we found that the FWS with their laminar flow-do a great job of removing surface water without stirring up all the stuff under the water surface.HMT > Products > Internal Floating RoofsHMT offers a comprehensive line of internal floating roofs for aboveground storage tanks.

The two main types of floating roofs designated by API 650 are external (Annex C) and internal (Annex H). External Floating Roof (Annex C)Storage of crude oil with vapour pressure higher than 11 , best floating roof oil typesI am currently looking at options for large storage tanks (> 100000 bbls) for hot crude oil. Currently the true vapour pressure is approx 13.5 psia at the storage temperature. The tank designers are of the opinion that above 11 psia, this excludes standard atmospheric or cone roof tanks or floating roof tanks.
When emptying floating roof tanks, landing the legs will create a vapor space above the liquid, thus causing air to be drawn in through the roof seals. The resulting atmosphere may be in the flammable range.
