• Reviewed and assessed separator vessel adequacy documentation per API 12J, verifying residence time, vapor-
liquid separation performance, and nozzle momentum compliance.
• Reviewed and verified heat exchanger thermal adequacy reports (HTRI) for critical exchangers, covering fouling
tendency, vibration risks, and overall thermal performance.
• Assessed flare system adequacy documentation, confirming header backpressure limits for both normal
operation and emergency depressurization (EDP) scenarios.
• Performed and validated hydraulic adequacy checks for existing piping systems, confirming acceptable fluid
velocities, pressure drops (ΔP), and control‑valve authority.
• Prepared and coordinated Design Basis, HMBs, PFDs, P&IDs, line sizing and datasheets in alignment with licensor
(Axens) and SAES/API requirements.
• Supported HAZOP/LOPA reviews and managed action closeouts for critical deviations; ensured alignment with
SAES‑L‑132, SAES‑G‑005, SAES‑B‑058.
• Drove no‑CAPEX revamp philosophy by validating reuse of existing vessels/exchangers/pumps via mechanical
adequacy checks and performance verification.

Additional support on CDU pump upgrades, overhead compressor replacement, steam network optimization,
Mercury removal in naphtha, EPR flare optimization, and Merox/LCO‑to‑VGO jump‑over modifications.

• Designed tank farm and utility systems including API 2000 safety devices; executed pump sizing and control
valve selection.
• Built hydraulic models for cooling water, steam, and utilities; conducted surge/transient analysis for critical
lines.
• Delivered FEED for PETROKEMYA Benzene Off‑Gas transfer to AR‑RAZI, including PFDs, P&IDs, PSV/valve sizing,
and steady‑state simulations.
• Engineered Maaden Umm Wual wellfield and 64.5‑km transmission pipeline; performed steady‑state and
surge analysis, booster pump sizing, and buffer tank sizing.

• Led process improvement and cost‑reduction studies for base‑oil production; prepared performance monitoring
dashboards.
• Supported operations troubleshooting and commissioning activities, including Base Oil Color Improvement
project.

• Verified heat exchanger performance and carried out hydraulic sizing for process gas pipelines.
• Participated in plant troubleshooting, HAZOP proceedings, and modification studies to improve reliability.

• Performed HYSYS simulations, PipeNet hydraulic calculations, and HTRI‑based exchanger design ratings.
• Developed Mass & Heat Balance, line sizing, and control valve datasheets for multiple projects.
