Introduction
This practical training course provides a comprehensive walk-through of the key operational aspects of Urea Synthesis and the High-Pressure (HP) Recovery Section, with particular emphasis on the daily responsibilities of Senior Field Operators.
The course focuses on practical field knowledge rather than extensive theoretical concepts. It covers normal operation, process monitoring, equipment behavior, abnormal operating conditions, troubleshooting, process upsets, corrective actions and safe operator response.
Participants will work through realistic operating situations and three practical case studies to develop a systematic approach to identifying abnormalities, analyzing possible causes and taking appropriate corrective actions.
Course Objectives
