Failure Analysis and Field Repair of Urea reactor

Abstract

The outer shell of a Multi-layered Urea reactor ruptured while the plant was in operation. The plant madean emergency shutdown, samples were collected, and an investigation carried out to establish the root cause of the failure. The paper explains the detailed analysis performed, corrective action implemented, and a health assessment for the equipment’s safe working. The paper also includes references to similar failures in old multi-layered urea reactors subsequently and the mitigation plans to avoid such failures.
