Design Analysis of Butene Storage Spherical Tank

Spherical storage tank for chemical plant is analyzed for the loads and their combinations in accordance with Section Ⅷ, Division 2 of the ASME Boiler and Pressure Vessel Code. Design Analysis of Butene storage tank is carried out by utilizing 3-dimensional plate and beam elements of a general purpose finite element program. Two separate 3-D finite element models are used; one for the global analysis of the entire spherical storage tank, the other for the local analysis of junction part and its vicinity of shell-to-supporting structures. The analysis is focused on the equator plate in the shell and the junction part of shell-to-supporting structures.
