Storage Tanks – Selection of Type, Design Code and Tank Sizi

ABSTRACT
The present work gives an insight into the proper selection of type,
design code and sizing of storage tanks used in the Petroleum and Process
industries. In this work, storage tanks are classified based on their design
conditions. Suitable design codes and their limitations are discussed for each
tank type.
The option of storage under high pressure and ambient temperature, in
spherical and cigar tanks, is compared to the option of storage under low
temperature and slight pressure (close to ambient) in low temperature and
cryogenic tanks.
The discussion is extended to the types of low temperature and
cryogenic tanks and recommendations are given to select their types. A study
of pressurized tanks designed according to ASME code, conducted in the
present work, reveals that tanks designed according to ASME Section VIII
DIV 2 provides cost savings over tanks designed according to ASME Section
VIII DIV 1.
