The crude oil terminals often have large throughputs, and the fire risk of crude oil is high. Hence, the fire design standards are becoming more and more stringent, which makes it difficult for some old crude oil terminals to meet the relevant provisions of the new standards. In this study, we took a typical old crude oil terminal as an example, and utilize TNO software simulation to assessment the pool fire consequences. Several issues caused by the changes in the old and new standards are analyzed, such as the fireproof distance, explosion-proof and fireproof. Furthermore, we have put forward targeted solutions and treatment principles to help enterprise better deal with them.
