Analysis of vertical pressure vessel with skirt support

Abstract

Emphasizing safety has been the top priority in the design of pressure vessels because of their frequent exposure to high-pressure, high-temperature conditions and potential containment of hazardous materials. It is essential to make sure that these containers are impervious to leaks and strong enough to resist the rigors of their operational environment. This study aims to investigate the exact design of a vertical pressure vessel (PV) in accordance to Section VIII, Division 1 of the Boiler and Pressure Vessel (B&PV) Codes of the American Society of Mechanical Engineers (ASME). The study considered various loads by following the UG-22 criteria. Utilizing a 2D axisymmetric model in ANSYS APDL, we conducted a comprehensive simulation to assess the vessel's performance. Following Section VIII, Division 2 of the ASME B&PV Codes, our evaluations cover structural, thermal, and thermo-structural aspects to prevent plastic collapse. Special attention is given to the junction of the vessel's skirt and head, identified as a zone with elevated temperature (Hot Box). This region was subjected to Extensive finite element analysis (FEA) to ensure that the stress levels remain in the acceptable bounds.
