Petrochemical Process Fundamentals

Evaluates foundational understanding of petrochemical industry workflows including upstream, midstream, and downstream operations. Tests knowledge of feedstock processing, unit configurations, common products (e.g., olefins, aromatics), and typical refinery/petrochemical integration. Candidates must demonstrate a clear grasp of basic thermodynamic and chemical principles applied across different process stages.

Equipment Types & Functions

Assesses technical familiarity with the function, design intent, and operational role of core static and rotary equipment (e.g., reactors, distillation columns, heat exchangers, compressors, pumps). Also includes condition monitoring basics, startup readiness checks, and recognizing early signs of equipment failure or malfunction in a plant environment.

PFDs and P&IDs Interpretation

Tests practical ability to read, interpret, and navigate Process Flow Diagrams (PFDs) and Piping & Instrumentation Diagrams (P&IDs). Covers isolation strategies, valve and line identification, instrumentation symbols, safety interlocks, and the use of drawings for shutdown planning or maintenance coordination.

Unit Operations & Field Tasks

Focuses on routine and critical field activities such as local gauge reading, equipment patrols, leak checks, line tracing, and troubleshooting abnormalities. Also covers working knowledge of unit-specific operations like fractionation, cracking, reforming, or polymerization, based on process layout.

DCS/Control Room Operations

Assesses control room competency in monitoring plant health via Distributed Control Systems (DCS), handling alarms, initiating setpoint adjustments, and collaborating with field operators. Includes exposure to interlock logic, trip signal verification, and control loop awareness in real-time decision-making.

Shutdowns, Startups, and Equipment Handover

Tests deep operational knowledge of safely executing start-up and shutdown sequences, nitrogen purging, steam blowing, depressurizing, and handing over equipment for maintenance. Also evaluates sequencing logic and handover documentation as per SOPs.

SOPs, PCPs & Documentation Practices

Evaluates understanding of creating, following, and updating Standard Operating Procedures (SOPs) and Process Control Procedures (PCPs). Covers document control, versioning, alignment with HAZOP recommendations, and integration with audit or compliance systems for process governance.

Permit to Work & Safety Systems

Tests knowledge of industrial safety compliance through the Permit-to-Work (PTW) system including hot work, cold work, confined space entry, and work-at-height. Includes Lockout/Tagout (LOTO) procedures, Job Safety Analysis (JSA), risk hierarchy, and safe job execution principles.

Emergency Handling & Trip Recovery

Assesses preparedness and structured response to plant emergencies such as fire, toxic gas leaks, unit trips, and electrical blackouts. Covers emergency SOPs, equipment isolation, communication protocols, muster point awareness, and safety system engagement.

Planning, Compliance & Team Leadership

Evaluates supervisory capabilities in production planning, turnaround coordination, team assignment, permit validation, MOC (Management of Change), and interdepartmental communication. Tests managerial alignment with KPIs, plant availability targets, and regulatory expectations.
