Description

Project Overview

The project involves setting up of a Greenfield 9 MMTPA refinery-cum-petrochemical complex at Pachpadra in Barmer district of Rajasthan. With a processing capacity of nine million tonnes of crude oil per annum (Mtpa), the refinery complex will produce environment-friendly clean fuels, as well as petrochemicals to be used as feedstock in packaging, textile, and petroleum industries.

Project Progress and Timeline

  • Physical Completion: 82% as of September 2024, with crude pipelines nearing 94% completion.
  • Crude Unit Start: October 2025, with phased commissioning of downstream units to follow.
  • Full Operations: Expected by December 2025, ramping up to 80% capacity by year-end and full utilization by 2027.
  • Petrochemical Integration: Polypropylene, LLDPE, and HDPE units to begin operations in early 2026, three months after refinery startup.

Key Features and Units

  • Crude Mix: Designed to process both indigenous Rajasthan crude and imported Arab mix crude (initially 1.5 MMTPA Rajasthan crude + 7.5 MMTPA Arab mix; shifting to 9.0 MMTPA Arab mix after 8 years)[1]
  • Process Units: The facility will have 29 process units; major units include[1][2]
