Olefins Plant
An olefin, or alkene, is an unsaturated
chemical compound containing at least
one carbon-to-carbon double bond. It is
a basic ingredient in many chemical and
polymer products.
Production:
- Ethylene: 1,900 KTA

- MTBE: 85 KTA
- Motor gasoline : 950 KTA
PRODUCTS AND THEIR END USES:
TECHNOLOGY FEATURE:
Ethylene
The Steam Crackers
It is a basic building-block for making a wide variety of chemical and
polymer products, including polyethylene.
Uses: Detergent, plastic bags, film, paint, cosmetics.
Propylene
It is a basic building-block for making polypropylene, polymers and other
chemicals.
Uses: Carpets, upholstery, thermal underwear, yachts and polymer
banknotes.
Butenes
Butenes are used as a feedstock in the synthesis of intermediate alcohols.

Methyl Tertiary Butyl Ether (MTBE)
It is an additive used in motor gasoline to raise the oxygen content and
octane number.
Uses: Octane enhancer and anti-knocking agent in motor gasoline.
The heart of the chemical plant are two
world-scale steam crackers that use
proprietary technology to process
hydrocarbon feed molecules into basic
building blocks such as ethylene, propylene
and butene-1. These are subsequently
fed into the polymers plants to produce
polyethylene, polypropylene and specialty
elastomers. Butene serves as a feedstock to
the oxo alcohol plant to produce to produce
iso-nonyl alcohol and also to the polymers
plants as a co-monomer feed. Benzene,
which is produced from the steam cracker,
is recovered at the aromatics plant. Other
by-products from the steam crackers are sent
to the cogeneration units to generate steam
and electricity for use by the chemical plant.
This makes the plant an energy-efficient
manufacturing facility.

Utilities
Utilities, such as electricity and steam, are needed
to support the production of chemicals in the
various units of the Singapore Chemical Plant.
Production:
- Power generation: 360 MW
- Steam: 1650 T/h
USES IN MANUFACTURING:
TECHNOLOGY FEATURE:
Steam is produced for heating purposes
and for driving large turbines, while
electricity is produced to power electrical
motors and product extruders around
the plant. Fuel gas is fired in the heaters
and furnaces to provide heat energy to
the processes.
Cogeneration
The four large heat recovery steam generators (HRSG) at the plant embrace
the concept of co-generation where steam and electrical power are generated
at the same time. Fuel and air are first combusted and the hot air produced is
used to turn gas turbines to generate electricity. The effluent gas is then sent to the HRSGs where heat energy is recovered to produce steam.
Cogeneration enables the maximum amount of energy to be recovered per
unit of fuel consumed. This reduces the overall amount of fuel used and
lowers greenhouse gas emissions. Excess electricity generated is sold to the
Singapore PowerGrid.
Waste Water Treatment
All waste water treated at site meets the discharge specifications required by
the National Environmental Agency (NEA). Waste water treatment uses both
the traditional Bio-Oxidation (BIOX) technology, as well as the state-of-the-art
Membrane Bioreactor (MBR) technology. Using the MBR technology, the quality
of effluent water can be made clean enough to be recycled directly back into
the process. This reduces the overall amount of fresh water used in the plant.
