Transient Cooling of Waxy Crude Oil in a Floating Roof Tank


Transient Cooling of Waxy Crude Oil in a Floating Roof Tank

The transient cooling of waxy crude oil stored in a floating roof tank located in alpine region is studied by means of numerical simulation, accomplished with a two-dimensional model in cylindrical coordinates with the finite volumes method. The typical evolution of transient natural convection and temperature distribution is investigated which can be divided into four stages.sp.info Crude oil storage tanks: types, design, dimensionsFloating roof oil tanks have a cylindrical steel shell. As the name of the tank suggests, this cylindrical steel shell has a floating roof, meaning that it floats on top of the liquid that is in the tank. This is a very interesting concept. When the crude oil levels are low, then the position of the roof will be low as well.sp.info Tanks Emissions for TRI Reportinghad a floating roof to account for clingage.
