CH. 5 Environmental Protection

CTCI has long been committed to introducing and
developing green engineering technologies. From
perspectives of design, procurement, construction,
commissioning, operation, and decommissioning, we offer
businesses economic and viable energy-saving solutions.
With the global trend of actively responding to climate
change and decreasing greenhouse gas emissions, we
have addressed the issue of sustainable growth and
management of natural resources. CTCI has incorporated
environmental protection into its business continuity
management, leading green engineering management
in Taiwan as a pioneer. Under the CSR committee,
the company has established a cross-department
environmental protection group. In addition to enhancing
energy-saving and environmental management of
operating sites, the group also offers clients energy-
saving and carbon-reduction services. In the proposal and
execution of a project, we offer businesses the optimal
energy-saving suggestions, helping them contribute
to mitigating climate change and coexisting with the
environment, so that the construction of a plant is a part of
the mission to protect the environment. We hope to, with
our partners in the value chain, minimize pollution, lower
the risks that impact human health and the environment,
and innovate to increase the green competitiveness of
the industry. Thus, we concretely create win-win situations
for CTCI, partners, stakeholders, society, and the
environment and to contribute to the sustainability of our
ecosystem.

Measures
Application Case or Results
Energy and water saving
during processes
● Updating process technologies or adopting
optimal process designs
● Recycling waste heat from processes or using
regenerative thermal oxidizer for treating VOC
waste gases (Note 1).
● Recycling reusable steam condensate as water
supply for the deaerator; Reusing waste water
from processes after being sorted and treated.
● Increasing equipment efficiency and productivity
● Minimizing fuel consumption from steam generation
● Minimizing water consumption
Energy-saving for rotary
machinery
● Optimizing rotary machinery systems, improving
transmission efficiency
● High-efficiency motors: Increasing electricity efficiency by
20% to 25%
● Using inverters: Achieving better control for process
systems, lower machinery maintenance cost, lower noise
output, and increased adaptability to system changes
Energy-saving for
electrical engineering
technologies
● High-performance transformers: Using
amorphous metal transformers and permalloy
silicon steel transformers to minimize loss of no-
load iron cores
● High-performance lighting and outdoor lighting
switches: T5 blast-proof LED indoor and
outdoor lighting; Manual lighting switches for the
maintenance platform of the outdoor process
tower
● Transformers: Increasing performance while extending
service life; Decreasing greenhouse gas emissions;
Much energy consumption can be saved in production
processes, and materials can be re-used.
● Lighting: Minimizing light pollution and greenhouse gas
emissions
Air pollution prevention
● Hydro-desulfurization and selective catalytic
reduction (SCR) (Note 2).
● Using denitrification, desulfurization, and dust
removal units to treat the pollutants between
the exhaust port and the chimney
● Incorporating the Dyna Wave process
● Reducing emissions of air pollutants, including suspended
particulates (PM2.5).
● Reducing the concentration of exhaust gas (including SO
2
,
NOx, and particulates) more effectively than traditional tail
gas treatment methods
● Achieving the standard for best available control
technology
● Reducingannual NOx emission by more than 246,000 tons
Waste water treatment
● Advanced dual-layer upflow anaerobic sludge
blanket
● Process technologies and membrane bio-
reactor (MBR) (Note 3).
● Using electrodialysis reversal (EDR) in industrial
waste water recycling (Note 4).
● Over 70% of COD removal rate; The 60% of methane in the
biogas is used as fuel for the plant.
● Increasing waste water treatment performance
● Decreasing risks during water shortage
