CH. 5 Environmental Protection
80
In the process of executing a project, applying green
engineering to constructions while continuing to develop new
technologies is the greatest technical challenge for the sustainable
growth of an construction company. Supported by technologies,
CTCI uses the latest eco-friendly processes in all its current plant
construction contracts. Compared with the previous generation of
processes, environmental impact has been significantly decreased,
which shows that we have contributed to both economic
growth and environmental protection. With strong engineering
development capabilities and technological background, we
are able to more quickly accumulate technical experience when
involved in international constructions and collaborating with
international construction companies. CTCI not only continue to
develop green technologies but has also applied its technologies
in many plant construction projects and has achieved outstanding
results.

Note 1: RTO = Regenerative Thermal Oxidizer
Note 2: MMA/PMMA = Methyl methacrylate / Poly Methyl methacrylate
Note 3: RFCC = Residual Fluid Catalytic Cracker
Note 4: DHDS = Diesel Hydrodesulfurization
Note 5: LCD = Liquid Crystal Display
Note 6: Annual electricity saved is calculated based on 24-hour operation for 365 days per year. According to information published by
the Bureau of Energy, Ministry of Economic Affairs in 2014, the CO
2
e per kWh of electricity is 0.521 kg. Annual electricity saved in outdoor
lighting is calculated based on 12-hour operation for 365 days per year; Calculation for indoor lighting is 24-hour operation for 365 days
per year.
