Case Study Explanation- New Pump Shutoff Head
In the design of process facilities, overlooking seemingly minor details can lead to major safety and #operational challenges. This case study explores a real-world scenario where the #procurement of a #centrifugalpump for a new #petrochemical plant unveiled an unexpected #overpressure risk in the discharge system.
#discover how a deviation in the pump's shutoff pressure from initial estimates led to a potential overpressure situation for a critical heat exchanger. Learn about the various solutions considered by the engineering team, including safety interlocks, pressure #relief valves, and equipment upgrades, and the trade-offs involved in each approach.
This case study highlights the criticality of thorough equipment #evaluation , effective #communication between stakeholders, and a holistic approach to risk mitigation in process design. Whether you're a process engineer, project manager, or safety professional, this video offers valuable lessons to enhance your knowledge and decision-making skills in similar scenarios.
Description of the Problem: The case study focuses on an overpressure hazard discovered during pump procurement. When the actual pump curves arrived, the pump’s real #shutoff pressure (28 barg) exceeded the #design pressure and MAWP of the downstream heat exchanger HX-101, which had been designed for only 25–26 barg. This mismatch created a critical safety risk: HX-101 could fail if a #blockage occurred while the #pump was running. The case study examines how this pressure mismatch was identified and how the #team ultimately resolved the issue by upgrading the exchanger.
