World’s Largest & India’s First LC-MAX™ Residue Upgradation Facility
Project Name: RUF (Residue Upgradation Facility) – Visakh Refinery Modernisation Project (VRMP), HPCL, Visakhapatnam
Project Description:
World’s largest and India’s first LC-MAX Residue Upgradation Facility for HPCL at Visakh Refinery, Visakhapatnam. Using advanced LC-MAX™ technology from CLG and KBR, the facility converts heavy refinery residues into high-value fuels like naphtha, gasoline, diesel, and LPG — delivering a 93% conversion rate, far above industry norms.
- 3.55 MMTPA high-efficiency LC-MAX Reaction Unit
- Compact site footprint (300m × 180m) within an operating refinery
- 50–60% modularised execution with modules from L&T Hazira, Kattupalli & global yards
- India’s first fully precast substation buildings
- Three LC-MAX reactors manufactured by L&T Heavy Engineering
- 7,200 workforce and 37 cranes deployed at peak, including 3,200 MT, 2,000 MT & 1,600 MT cranes
- Achieved 50+ million safe man-hours with Zero LTI
This landmark project strengthens India’s refining efficiency, energy security, and clean-fuel capability.
