摘要

At present, storage capacity of single tank and tank farm has been greatly increasing. For the applicability of current design standards, the change poses a real challenge. This paper focuses on the applicability of safety spacing between tanks, which is one of the most important parameters of tank farm safety design. Taking PHAST and FDS as main research tools, the accident consequences of different accident scenarios for different scales of oil tanks were calculated to study the safety performance change caused by the increase of capability. The research results show that, when current standards are used to design the safety spacing between tanks, the safety performance increases as the capability increase. Considering the high property density, when designing the safety spacing for ultra-large oil tank, it is suggested that more strict safety performance target be chosen.
