Requirements

Bridge the Gap Between Engineering Theory and Plant Reality.

In the world of Process Engineering, a Pressure Relief Valve (PRV) is not just a component; it is the final barrier between safe operation and catastrophic failure. While universities teach the physics, the industry demands a deep understanding of codes, complex relief scenarios, and sizing precision.

I am Swati Thuturkar, and I have spent over 21 years navigating the technical landscapes of global giants like Reliance Industries, KNPC, and Tecnimont. I created this course to transfer that “on-the-ground” knowledge to the next generation of chemical and process engineers.

This course isn’t just a lecture; it is a Technical Mentorship. We move beyond basic definitions to explore the rigorous standards of API 520, 521, and ASME Section VIII, ensuring you can handle any safety challenge a refinery or petrochemical plant throws at you.

What You Will Learn

  • The Fundamentals: Master the force-balance physics of spring-loaded, bellows, and pilot-operated valves.
  • Code Compliance: Understand the critical nuances of ASME Sec VIII and API 520/521/526.
  • Relief Scenario Analysis: Learn how to identify and calculate for cases like Blocked Outlet, Fire, Thermal Expansion, and Tube Rupture.
  • Advanced Sizing: Step-by-step tutorials on calculating orifice areas for gas, liquid, and steam services.
  • Installation Best Practices: Avoid common field errors in inlet/outlet piping that lead to “chattering” and valve failure.
