The successful commissioning of the Residue Upgradation Facility (RUF) at HPCL’s Visakh Refinery, featuring the world’s first and largest LC-Max unit, marks a major milestone in India’s refining journey. Engineers India Limited (EIL), as Project Management Consultant (PMC), provided comprehensive PMC services for this landmark facility, which sets a global benchmark in scale, technological complexity, and execution excellence. The 3.55 MMTPA Residue Upgradation Facility, implemented as part of the Visakh Refinery Modernization Project (VRMP), ranks among the most complex and technologically advanced residue processing facilities commissioned worldwide. EIL delivered end-to-end project management and engineering services across the entire project lifecycle, while Larsen & Toubro (L&T) executed the project as the EPC contractor. The facility deploys LC-Max technology, a world-first at this scale, enabling an exceptional 93% conversion of bottom-of-the-barrel residues into high-value distillates. This significantly enhances refinery margins, improves refining complexity, and maximizes value extraction from every barrel of crude—aligned with India’s growing energy demand. The successful commissioning of the facility reflects seamless collaboration among HPCL, EIL, L&T, licensors, vendors, and project teams, who collectively navigated unprecedented technological, logistical, and execution challenges to deliver a project to global standards. For EIL, the commissioning of the LC-Max-based RUF adds another “First” to its six-decade legacy of delivering complex, mission-critical energy infrastructure for the nation. The project further reinforces EIL’s position as a world-class consultancy, capable of managing frontier technologies and mega-scale projects with precision and reliability. This achievement strongly aligns with the Hon’ble Prime Minister’s vision of “Atmanirbhar Bharat”, demonstrating India’s ability to conceptualize, engineer, and execute cutting-edge refining technologies domestically, while strengthening national energy security. The Residue Upgradation Facility at Visakh Refinery is poised to serve as a global showcase project, setting new benchmarks in technology integration, execution excellence, and indigenous capability in the refining sector.
