HPCL Starts Up 3.55 MMTPA Residue Upgradation Unit at Visakh Refinery

The LC-Max upgrade is designed to lift distillate yields and margins, placing the site among India’s most complex refineries.

Overview

  • The unit uses LC-Max-based residue hydrocracking to convert about 93% of bottom-of-the-barrel oils into higher-value products.
  • HPCL projects up to a 10% increase in distillate yield and stronger gross refining margins by enabling processing of heavier and opportunity crudes.
  • Commissioning lifts the Visakh refinery’s Nelson Complexity Index to 11.6 as part of the wider modernisation program.
  • The facility houses three LC-Max reactors of roughly 2,200 tonnes each, with key equipment fabricated in India under the Aatmanirbhar initiative.
  • Engineers India served as project management consultant and Larsen & Toubro was the EPC contractor, and HPCL has deployed a digital optimisation suite with real-time monitoring and AI-driven control.
