ABSTRACT

Firefighting water system in some refinery in Shandon province is simulated by EPAnet software. The worst using condition of firefighting water system is checked and studied. By analyzing point pressure and piping velocity, some optimization design measures are taken. These measures may reduce engineer investment and be used to check and optimize firefighting water system in similar refinery.
