Design Basis & Overpressure Scenario Evaluation
ZAP first issued a documented design basis fixing calculation methods and assumptions for client agreement before analysis began. Field data gathered during site visits was combined with client models and process simulation to evaluate piping losses, relieving temperatures, and materials of construction. Scenarios assessed included fire, hydraulic expansion, blocked outlet, control device failure, abnormal heat input, exchanger tube rupture, and vessel overfill.
Staged, Code-Compliant Mitigation Recommendations
Where devices were found inadequate, ZAP recommended mitigation in a staged hierarchy favoring the least intrusive modification, giving the client a prioritized, code-compliant basis for relief system upgrades. The project demonstrates ZAP’s capability to perform comprehensive relief and flare system studies on live, operating cryogenic gas processing facilities.
