Projeto de um tanque de armazenamento atmosférico com teto flutuante para estocagem de gasolina

In this paper are discussed the main project stages of an atmospheric storage tank with floating roof. It emphasizes the calculations of the bottom, the shell and the floating roof, discussing its stages and conditions, based on the technical standards of the project. The storage tanks are static equipment working under low pressure and has an essential importance for the operation of a process plant. This paper has the purpose of obtaining the dimensions and materials of each component of the tank through the calculations and prove them with results obtained by numerical simulation by finite elements with the help of Autodesk Inventor software, consolidating the project
