Design and modelling of hemispherical and flat dish end pressure vessel

Abstract

Pressure vessels are widely used in industries for processing and storing fluids which are at different temperature and pressure in analogous to ambient. The design of these pressure vessels become the most paramount factor as any discrepancy would cause the vessel to explode, leading to injure many humans and failure of the setup. This paper designs the pressure vessel according to the pressure vessel handbook for both hemispherical and flat dish end pressure vessel so as to determine the most economic and efficient design. The various stresses engendered within the vessel were calculated and were learned to be within the permissible limits. The outer and inner diameter of the vessel was found to be 607mm and 480mm and the thickness of the vessel was determined to be 63.5mm. This design could withstand an internal pressure and temperature of 150psi and 500°F. The dimensions obtained from the design were further used to model both hemispherical and flat dish end pressure vessel with help of CAD in Catia V5R19.
