Basic Engineering Design (BED) for Vacuum Fractionation Unit (VFU) Optimization Project

MECIP was awarded the Basic Engineering Design (BED) for the Vacuum Fractionation Unit (VFU) Condensate Residue High Rundown Temperature and Bottom Loop Congestion Improvement Project at a Major Refining Company in Malaysia. The project was initiated to address operational challenges arising from increased condensate residue production, resulting in elevated rundown temperatures and recurring congestion within the vacuum fractionation column bottom system.

The scope involved comprehensive multidisciplinary engineering studies and design development to identify practical and sustainable solutions for improving VFU performance, process reliability, and operational flexibility. MECIP carried out process simulations, hydraulic evaluations, heat exchanger sizing, pump and relief system assessments, utility adequacy studies, and detailed process safety reviews, including HAZID, HAZOP, and hazardous area classification studies.

The engineering package covered process, mechanical, piping, rotating equipment, electrical, instrumentation, civil and structural, corrosion, and inspection disciplines. Key deliverables included process design basis development, PFDs, P&IDs, equipment and piping layouts, stress and mechanical integrity assessments, electrical system studies, foundation and structural evaluations, material selection reviews, and comprehensive EPCC cost estimates. The project also incorporated engineering design for pump tie-in modifications, supporting future implementation and integration with existing refinery facilities.

Through the application of advanced engineering tools and refinery expertise, MECIP delivered a robust engineering solution that established the technical foundation for enhancing VFU operability, mitigating process bottlenecks, improving equipment reliability, and supporting the long-term optimization of refinery operations.
