ABOUT BASF
BASF SE is a German chemical company and the largest chemical
producer in the world. The BASF Group comprises subsidiaries and
joint ventures in more than 80 countries and operates six integrated
production sites and 390 other production sites in Europe, Asia,
Australia, the Americas and Africa. Its headquarters is located in
Ludwigshafen, Germany. BASF has customers in over 190 countries
and supplies products to a wide variety of industries. Despite its size
and global presence, BASF has received relatively little public
attention since it abandoned manufacturing and selling BASF branded consumer electronics products in the 1990s.
At the end of 2017, the company employed around 115,490 people,
with over 52,000 in Germany alone. Between 1990 and 2005, the
company invested €5.6 billion in Asia, for example in sites near
Nanjing and Shanghai, China and Mangalore, India.
BASF is listed on the Frankfurt Stock Exchange, London Stock
Exchange, and Zurich Stock Exchange. The company de-listed its
ADR from the New York Stock Exchange in September 2007. The
company is a component of the Euro Stoxx 50 stock market index.
ABOUT BASF, DAHEJ SITE
Project Type
Integrated chemical complex
Construction Started
2012
Commissioned
October 2014
Investment
INR10bn (approximately $180m)
BASF India’s chemical production complex at Dahej, Gujarat, started
operations in October 2014. At approximately INR10bn ($180m), it
is the biggest investment made by BASF in India.
The complex is located at the 453km² Dahej Petroleum, Chemicals
and Petrochemicals Investment Region (PCPIR). Planning for the
project started in mid-2011, the investment decision was made in
April 2012 and construction activities were completed in 2014 with
zero lost-time incidents.
The chemical complex integrates polyurethane manufacturing
facilities, as well as production facilities for care chemicals and
polymer dispersions to cater to the growing appliances, footwear,
automotive, construction, coatings, paper and home and personal care
industries.
The polyurethane plant produces BASF’s proprietary Elastollan
thermoplastic polyurethane (TPU), Cellasto
microcellular
polyurethane components for automotive NVH (noise, vibration and
harshness) parts, and other polyurethane products applied primarily
in cold and heat-insulation applications.
The plant also integrates production facilities for precursors, such as
polyetherols and polyesterols, and an MDI (methylene diphenyl
diisocyanate) splitter, the first of its kind in South Asia, for
processing crude MDI.
The care chemicals facility at the site, which integrates the
company’s first sulphation plant in the country, produces surfactants
for home and personal care.
The polymer dispersions plant, which complements the company’s
existing dispersions facility in Mangalore, produces BASF’s
proprietary Acronal and Styrofan products for architectural coatings,
adhesives and construction, Styronal and Basonal for paper coating,
and Basoplast for sizing.
The project involved the construction of associated infrastructure,
including non-plant buildings, a demineralised water plant, a boiler, a
cooling tower, a thermal oxidiser, a compressor, a tempered water
package, a wastewater treatment plant, a 66KV switchyard, a fire and
gas system, storage facilities, utilities and offsites.

DECLARATION
An Engineer is one who converts the theories of the textbooks into
the practical working models and processes. We learn many things
more perfectly and accurately through observations and applications.
Learning in classes just gives us the basic idea about any process,
while at the same time industrial training helps us to understand the
detailed and thorough working of that particular process. Hence, we
can clearly understand the principle application of the theoretical
study.
This report consists the various unit operations and operational
details of the plant. This report has been prepared on basis of
information collected and provided during the vocational training I
underwent at BASF India Pvt. Ltd., Dahej. The information given in
this report is true as per my knowledge and data provided by the
industry.

CONCLUSION
The summer training was useful in enhancing our understanding
of the engineering profession technically. In a short span of two
weeks, I was able to learn and observe how work is being done in a
real industry. Practical understanding of all the equipment can be
correlated with the fundamental concepts of engineering. I learnt
technical skills along with having a hard-working attitude. Team
work is another factor one should incorporate in himself as it is
required in an industry to coordinate with all the colleagues
efficiently. This training also improved my soft and functional skills.
I am grateful to BASF for providing me with such an opportunity
which helped me in expanding my knowledge and gave me a new
insight about industries.
