Fire Exposure and Relief Protection for Vessels Containing Reactive Chemicals

The client was storing reactive materials in vessels that could be subject to fire exposure. They wanted to be sure that the relief protection on the vessels was correctly sized, or if not, what changes were necessary for an effective relief system.

A refinery approached ioMosaic for the purposes of ensuring that pressure relief capacity was adequate for the loss of liquid seal scenario in a high-pressure separator (2,000 psig). They were also concerned about the pressure waves that would occur in the high-pressure separator’s outlet lines on rapid closing of the isolation valves and sought our expertise.

A large oil refinery with a very complex flare network had become so complex that the tools the refinery was using to evaluate the flows through the flare network could not adequately model the system. Management no longer had confidence that their model results reflected the actual network performance and therefore, could not be sure the system would perform properly in the event of a global relief scenario at the facility.
