as the critical raw material for making purified terephthalic acid (PTA), needed to make polyester fibre, filament yarn and bottle grade resin
(PET). To date, the refinery is the only producer of ortho-xylene (OX), required for making phthalic anhydride that goes into the manufacture of ‘L’ Series Amino Acids Hydroquinone
plasticisers, among other uses.
Acetonitrile Isopropyl Alcohol
The refinery was also conceived with a high severity fluidised catalytic cracker (FCC), with a ~10% propylene yield. This served as monomer
for downstream polypropylene (PP) at compelling cost-economics. The Delayed Coker – amongst the largest in the world – employs severe Calcium Cyanamide Malononitrile
thermal cracking to convert low value heavier residues to higher value light products with rejection of metals into the petcoke coproduced. The
recovery of some of these metals – vanadium and titanium, in particular – is a task that is yet to be taken up. The gasification complex – also the Chlorosulfonyl Isocyanate O-Phthalodinitrile
world’s largest – converts this low-value petcoke to usable, high-value fuel (synthetic natural gas, SNG), making Jamnagar energy-efficient and
self-sufficient in meeting its power and utilities requirement. The Refinery Off-Gas Cracker (ROGC) produces up to 1.7-mtpa of ethylene, which Crotonaldehyde Para Chloro Benzonitrile
feeds into downstream plants for polyethylenes at attractive cost-economics.
Crotonic Acid Paraldehyde
Oil to chemicals – the next stage
The chemicals focus of the refinery is slated to increase in line with plans amongst other refining majors globally. As several studies have Cyanuric Chloride Phenothiazine
pointed out, petrochemicals already represent the fastest growing use for crude oil. Though sustainability pressures on plastics will have an impact
on demand for virgin polymers, markets for petrochemicals, as a whole, will continue to expand for the foreseeable future in India, though not Dicyandiamide Sodium Butyrate
perhaps at the fast clip of the past few decades.
Diisopropyl Ether Sodium Caprylate
While a typical naphtha cracker operating downstream of a refinery processes about 8-10% of crude oil for chemicals, tighter integrated schemes
such as that practiced by RIL in Jamnagar take the chemical conversion potential up to 17-20%. Newer greenfield oil-to-chemical (O2C) projects Glycolic Acid Tertiary Butyl Alcohol
aim to valorise up to 40-60% for chemicals. Jamnagar has some way to go in this respect.
Guanidine Carbonate Thiophenol
About four years ago, there was a plan to carve out the key oil and petrochemicals assets, including those in refining, fuel retail and aviation fuel,
into a separate unit. This was widely seen as a precursor to a stake sale to Saudi Aramco, the world’s largest oil producer, but that has not panned out. Guanidine Nitrate Triacetine
New energy initiatives Hydrobromic Acid 48% Valeronitrile
For now, the Jamnagar site is also being repurposed to locate the new energy initiatives of RIL, including the integrated manufacture of
polysilicon, silicon wafers, photovoltaic cells as well as solar panels. Investments are also being made into integrated battery manufacturing,
including the well-established lithium ion and the emerging sodium ion. Green hydrogen manufacturing is also a priority, with substantial investments PLEASE CONTACT WITH YOUR SPECIFIC REQUIREMENTS
allocated for electrolyser manufacturing, with aim of hitting a manufacturing cost of $1 per kg of green hydrogen. While there are many who doubt
this target is feasible, getting anywhere close will count as no mean achievement. The hydrogen so produced is expected to be used to make green CHEMET
fuels – e.g., green methanol using captured carbon dioxide, and other green fuels.
This reinvention of a classic refinery-petrochemical complex to a new energy hub is a mammoth and complex exercise and will mark another
chapter in the evolution of Jamnagar. Unlike the earlier changes, which essentially involved ramping up scale of a well-established set of operations, HEAD OFFICE : Span Centre, 2nd Floor, Ramakrishana Mission Road, Santacruz(West), Mumbai - 400 054, INDIA.
