Reliance Industries Ltd,(RIL) India's largest
Private Sector enterprise is also India's major
producer of Ethylene Oxide.
RIL has India's largest EO / EG Plant with an
installed MEG Capacity of 300 KTA and Pure EO
Capacity of 56 KTA..The EO/EG Plants, located
at Hazira near Surat in Gujarat are World Class
manufacturing facilities, set up with the technical
collaboration from ABB Lummus Crest, Netherlands
(Shell Process).Beginning with an initial Pure
EO Capacity of 24 KTA in 1992, RIL has now a total
Pure EO Capacity of 56 KTA.
Reliance has grown its Business by laying emphasis
on three critical areas:Quality,Safety and Customer
The Quality Management system at Hazira with
regard to Manufacture and Sales of Ethylene Oxide
has received an ISO 9002 accreditation. RIL has
a very strong orientation towards Health, Safety
& Environment and this philosophy has been
the guiding factor in fashioning its HSE Policies
& programs. Impressed by the Health &
Safety practices, the British Safety Council has
awarded a 5 Star Rating to the Hazira Manufacturing
RIL has the unique distinction of servicing its
EO Clientele round the year, with deliveries made
on all 365 days of the year. Proven ability to
deliver, coupled with a high level of Customer
Service has enabled the company to stay ahead
of the competition, and clearly emerge as a leader
in the domestic Ethylene Oxide market.
Ethylene Oxide is manufactured by the direct Oxidation
of Ethylene over silver catalyst to yield aqueous
Ethylene Oxide which is further purified to make
high purity Ethylene Oxide.
Ethylene oxide is a colorless gas condensing at
low temperatures to a mobile liquid. It is usually
stored in liquefied condition under pressure.
It is miscible in all proportions with water,
alcohol, ether and most organic solvents. Ethylene
Oxide vapour is inflammable and explosive.
Ethylene Oxide is packed in pressurised Road Tankers.
EO is a versatile petrochemical
capable of reacting with almost all the Organic
Compounds. The major applications of EO are in
the manufacture of:
1. Non Ionic Surfactants
Condensates of EO with Alkyl phenols, fatty alcohols
etc, find diverse use as non ionic surfactants
in the textile auxiliaries, binders, pharmaceuticals,
cosmetics and oil field chemicals
2. Glycol Ethers
It is made by reaction of EO with alcohol.Glycol
Ether is used in manufacture of brake fluids and
Mono, Di, Tri ethanolamines are formed when EO
is condensed with Ammonia. They are used for the
purification of natural gas in refineries and
4. Vinyl Sulphone
It is formed by the reaction of Acetyl Sulphonyl
chloride, Sodium bisulphate and EO. It is used
to manufacture Reactive Dyes for Cotton Fabrics.
5. Polyethylene Glycols
Higher glycols formed by the reaction of DEG /
MEG with varying molecules of EO. Depending on
the Molecular weight, the PEG’s find use in Pharmaceuticals,

Ethylene Oxide is a colourless liquid below
10.76oC and 760 mm of Hg, lighter than
water. It has a sweet, pungent ether-like odour.
Ethylene oxide is extremely flammable, highly
reactive and toxic compound. The vapours are heavier
than air and explosive in nature. Contamination
with many materials including metal oxides, metal
halides, acid and alkalis, metal hydroxides can
lead to runaway polymerization reaction which
always generates heat and can be explosively violent.
The liquid vaporises rapidly and can produce severe
eye and skin burns. Ethylene oxide may cause delayed
skin burns even if only dilute solutions remain
on the skin. Short term exposures to EO vapours
can result in difficulty in breathing, coughing,
lung irritation, dizziness, nausea, vomiting,
unconsciousness, and even death. Longer exposure
to high concentrations may cause severe damage
to lungs, nervous system, reproductive system
and other organs.
Ethylene oxide is also toxic to the developing
fetus and is mutagenic, suggesting it may cause
hereditary defects. Ethylene oxide is known as
animal carcinogen and there is a limited evidence
that it may cause cancer in man.
Training, proper personal protective equipment
and strict adherence to recommended and precise
work place practices are essential whenever ethylene
oxide is handled, used or stored.

SAFETY GUIDES :
Ethylene oxide (EO) is a hazardous material in
terms of toxicity, flammability and explosive
instability, however, it can be handled and stored
with safety provided appropriate precautions are
observed. This guide describes general properties
of ethylene oxide, hazards involved in handling
and the precautions which can be taken to minimize
the risks in handling ethylene oxide with the
aim of achieving a uniformity of approach to operation
and maintenance of chemical handling pure ethylene
oxide or mixtures in which ethylene oxide represents
a substantial proportion.
There is no suggestion that this guide represents
the final word and it is accepted that it may
have to be brought up to date as dictated by further
experience and technology changes.
