ENAP: LARGEST REFINERY CAPACITY ON
THE PACIFIC COAST
The state-owned company ENAP, with
annual sales of approximately 6.7 billion
US dollars and a profit of approximately
200 million US dollars (2005), is one of the
largest companies in Chile. As a strategically
important company, it is fully state
owned. ENAP operates plants in three
main locations: Punta Arenas, Talcahuano
(Concepción) and Concón and enjoys a
market share of 90% in the petrochemicals
market (petrol, diesel, aviation fuel,
asphalt). With a processing capacity of
approximately 100,000 barrels of crude
oil per day, the Concón refinery is the
main supplier for the Santiago region.
With its refineries, ENAP has the largest
refinery capacity on the pacific coast.
Santiago suffers from high traffic emissions,
a problem which is exacerbated by its
geographic location in a basin, which
makes air circulation difficult in certain
weather conditions. Against this backdrop,
the Chilean government pursues a strict
environmental policy with increasingly
rigorous emission reduction requirements.
The installation of the delayed coker as
well as the previous projects in which
MAN Ferrostaal acted as an investment
partner for ENAP were realized as part of
a long-term expansion and modernization
programme. The objective of this program
is to produce more clean fuels with
reduced emissions in order to further
improve the quality of life in the metropolis.
THE DELAYED COKER PROCESS
In the delayed coker process, oil sludge
and other viscous residues produced
during vacuum distillation (an oil processing
step) are converted into the valuable substances
liquefied petroleum gas (LPG),
gas, naphtha, diesel and petroleum coke
by rapid heating to approximately 540°
Celsius and subsequent transfer into special
containers (coke drums). Petroleum coke
is a valuable solid substance which can
be burned in power stations to generate

energy or used in the aluminium industry
to produce anodes, given appropriate
quality.
Due to their low proportion of short-chain
hydrocarbons, heavy crude oils yield less
high-quality products in the refinement
process than light crude oils. They also
produce more residues, which is why the
price of heavy crude oils on the global
market is lower than that of light crude oils.
The delayed coker converts these
residues into valuable products while
increasing the distribution of light oil products
and improving the product quality as
well as the efficiency and profitability of
the refinery.
