Design and Study of Floating Roofs for Oil Storage Tanks

Design and Study of Floating Roofs for Oil Storage Tanks Authors: Prof. Dr. Mohamed El-Samanody *, Dr. Ashraf Ghorab*, Ahmed Saad Noaman** *Department of Mechanical Power Engineering Ain Shams University **Senior Mechanical Engineer - Petrojet _____ Abstract - Floating roofs are widely used to store petroleum products with high volatility , floating roof oil fixed drawingDesign, Construction and Operation of the Floating Roof oil as one if it. There are different types of tank such as fixed roof tank, open roof tank, floating roof tank etc. Floating roof tank is which the roof floats directly on top of the product, with no vapour space and eliminating the possibility of flammable atmosphere.Floating roof tanks - PetroWikiClosed floating roof tank (CFRT) The closed floating roof tank (CFRT) is similar to an IFRT. It uses an internal floating roof but eliminates natural ventilation of the tank vapor space. Instead, the CFRT is equipped with a pressure-vacuum (PV) vent and may even include a gas blanketing system such as that used with fixed roof tanks. Emissions , floating roof oil fixed drawing
