Mathura Refinery, the sixth refinery of IndianOil was commissioned in 1982 with a capacity of 6.0 MMTPA to meet the demand of petroleum products in north western region of the country, which includes National Capital Region. Refinery is located along the Delhi-Agra National Highway about 154 KM away from Delhi. The major secondary processing units provided were Fluidised Catalytic Cracking Unit (FCCU), Vis-breaker Unit (VBU) and Bitumen Blowing Unit (BBU). The original technology for these units was sourced from erstwhile USSR, UOP etc. Soaker drum technology of EIL was implemented in VBU in the year 1993. For production of unleaded Gasoline, Continuous Catalytic Reforming Unit (CCRU) was commissioned in 1998 with technology from Axens, France. A Diesel Hydro Desulphurisation Unit (DHDS) licensed from Axens, France was commissioned in 1999 for production of HSD with low Sulphur content of 0.25% wt (max). With the commissioning of Once Through Hydrocracker Unit (licensed from Chevron, USA) in July 2000, capacity of Mathura Refinery was increased to 8.0 MMTPA.
Diesel Hydro-treating unit (DHDT) & MS Quality Up-gradation Unit (MSQU) was installed with world class technology from Axens and UOP respectively in 2005 for production of Euro-III grade HSD & MS w.e.f. 1st April 2005 as per Auto Fuel Policy of Govt. of India. Project for FCC Gasoline Desulphurization (FCCGDS) and Selective Hydrogenation Unit (SHU), the Prime-G technology of Axens, France was commissioned in February 2010 and supply of Euro-IV grade MS and HSD started on continuous basis from February 2010.
Mathura Refinery is having its own captive power plant, which was augmented with the commissioning of three Gas Turbines (GT) and Heat Recovery Steam Generator (HRSG) in phases from 1997 to 2005 using Natural Gas (NG) as fuel to take care of environment.
For upgrading environmental standards, old Sulphur Recovery Units (SRU) were replaced with new Sulphur Recovery Units with 99.9 % recovery in the year 1999. Additional Sulphur Recovery Unit is under implementation as a hot standby. Mathura Refinery had also set up four nos. of continuous Ambient Air Monitoring Stations far beyond the working area before commissioning of the Refinery in 1982 as a mark of its concern towards the environment and archaeological sites. Its close proximity to the magnificent wonder Taj Mahal adds extra responsibility towards maintaining a cleaner environment.
Mathura Refinery has planted 1, 67,000 trees in surrounding areas including refinery & township and 1, 15,000 trees in Agra region around Taj Mahal. The Ecological Park which is spread across 4.45 acres, is a thriving green oasis in the heart of sprawling Refinery.
At Mathura Refinery, technology & ecology go hand in hand with continuous endeavour for Product Quality up-gradation, Energy Conservation and Environment Protection. Mathura Refinery is the first in Asia and third in the world to receive the coveted ISO-14001 certification for Environment Management System in 1996. It is also the first in the World to get OHSMS certification for Safety Management in 1998 and 50001 certification for Environment Management System in 2018.
With the incoming of modern technologies, Mathura Refinery witnessed progression in its production capacity and keeping pace with the new Government policies of clean fuels, it became the pioneer in production and supply of Bharat Standard VI MS and HSD to Delhi/ NCR. Although, the refinery had produced BS VI fuel in 2016 and given some barrels to Honda and Mahindra- the auto giants for their engine testing purposes, the full fledged supply of these clean fuels started from January 2018.
Mathura Refinery has followed the vision of Prime Minister Narendra Modi towards "Make in India" and has commissioned a new Unit OCTAMAX, the breakthrough technology developed by IOC's R&D Centre that converts C-4 streams from Catalytic Cracker unit to high-octane gasoline (petrol) blending stream, thereby enabling compliance with stringent fuel quality norms.
Other future endeavours that underline the Refinery's commitment towards the environment include conservation of Yamuna river ecology. As part of this, Mathura Refinery recently entered into an agreement with the National Mission for Clean Ganga for using treated effluent (20 MLD) from a proposed Sewage Treatment Plant in Mathura - Vrindavan area, instead of fresh river water, for refinery operations in the next two years. Thus, from 2020-21, Mathura Refinery will stop drawing fresh water for industrial use from raw water sources and will instead use treated sewage water.
