Design and Development of Liquid Nitrogen Storage Vessel Using ASME Boiler and Pressure Vessel Code

Praharaj, Rajendra Kumar (2015) Design and Development of Liquid Nitrogen Storage Vessel Using ASME Boiler and Pressure Vessel Code. MTech thesis.



A pressure vessel is a closed container which is designed to store liquid or gas at a pressure or temperature, which is different from the ambient temperature and pressure. During operation, the pressure vessel has to withstand several induced stresses due to internal or external pressure. Thus, for the safety purpose storage vessels has to be designed according to ASME standards and rules. In most of the liquid nitrogen storage vessel, there was no proper control over the heat loss and differential pressure even in static condition which leads to fatal accidents and unnecessary loss of the LN2. Thus, it is important to design the fluid storage container such that no leakage can take place as well as the container has to withstand desired pressure and high or low temperature. The design mainly concerned with two chambers mounted concentrically out of which one experiences internal pressure and other experiences external pressure with proper fixture and connecting arrangements. The operating pressure is 0.1 MPa for both inside nitrogen storage vessel and outside vacuum jacketed vessel. The present work explores the proper design guidelines for the design of storage vessel which can which can withstand the differential pressure with minimum heat loss using ASME codes and standards. ASME Boiler & Pressure vessel code (ASME Sec VIII, Div-1, Edition 2010, Addenda 2011) has been used for the design of the vessel and materials are selected as per ASME Sec II Part A & D (M), Edition 2010. The connecting pipes are designed as per the ASME B 36.10. Finite Element Analysis and experimental testing have been carried out for validation
