ABSTRACT
The design of storage tanks for crude oil and petroleum products requires, in general, careful consideration of the following important factors:
• The vapor pressure of the materials to be stored • The storage temperature and pressure • Toxicity of the petroleum material
In order to meet the environmental constraints on air pollution, to prevent fire hazards, and to avoid losses of valuable petroleum products at the same time, it is recommended to adopt the following:
• The use of floating-roof tanks for petroleum materials with a vapor pressure of 1.1211.5 psia (at the storage temperature) or
• Using fixed-roof tanks along with the VRU system (to be described later).
