Introduction:

Process plant operations and troubleshooting form the daily reality of refinery control rooms and field operations. Operators continuously manage distillation columns, hydrotreating units, furnaces, hydrogen systems, pumps, and compressors while responding to alarms, process upsets, and changing product quality conditions.This training program presents structured operational frameworks, troubleshooting models, system interaction principles, and performance control structures used in modern process plants. It provides an institutional perspective on how operational reliability and fault management support production continuity, safety governance, and asset integrity.

Program Objectives:

By the end of this program, participants will be able to:

• Identify early signs of instability in refinery units such as distillation, hydrotreating, and reforming units.

• Interpret pressure, temperature, flow, and level trends to understand cause-and-effect across the process.

• Select correct operating actions during common refinery upsets and alarm flooding situations.

• Gain the required skills to apply structured troubleshooting steps to isolate root causes of process deviations.

• Respond effectively during abnormal and emergency conditions to protect personnel, equipment, and product quality.

Target Audience

• Refinery plant operators and senior technicians.

• Control room and DCS operators.

• Production and shift supervisors.

• Process engineers supporting operations.

• Maintenance coordination and reliability staff working with operations teams.

Program Structure:

Day 1: Process Plant Fundamentals for Refinery Operations:
