(2) Owner:

Bharat Aluminum Company Limited.

(3) Capacity:

Flue gas dust removal of 3×135 MW coal-fired power plant.

(4) Date of operation:

Unit 1 in December 2016, Unit 3 in March 2017 and Unit 4 in June 2017.

5) Investment, construction and operation:

The project is invested and operated by the Owner, SEPCO1 Electric Power Construction Corporation is the construction unit and Zhejiang Feida Environmental Science & Technology Co., Ltd. is the EPC contractor for dust removal and renovation.

2. Major environmental problems to be addressed

The emission of flue gas particles from the coal-fired power plant can meet the requirements of relevant emission standards.

3. Environmental standards and/or main index limits to be followed

Environment (Protection) Act, 1986, Environment (Protection) Amendment Rules: the particulate emission limit of thermal power plants installed since January 1, 2017 is 30 mg/m3.

4. Technological process

The last two of four electric fields of the original electrostatic precipitator were replaced by bag dust collectors, and the electrostatic precipitator as a whole was transformed into an electrostatic-fabric integrated dust collector.

5. Environmental pollution control effects

The emission concentration of particulate matter before renovation was 1,450~1,550 mg/m3, and after renovation the emission concentration of particulate matter was less than 30 mg/m3.

6. Social benefits

The project not only contributes to the local air pollution control, but also makes the particulate matter emissions from the owner-owned power plant meet the new emission requirements, and avoid additional costs such as government fines and claims from the surrounding residents.

7. Economic benefits

The successful renovation of the electrostatic precipitator guaranteed normal production of the Owner and promoted the local economic development.

Project significance: India is under rapid economic and urbanization development with increasing energy demand and thus it relies heavily on coal-fired power plants. Air pollution has posed an increasingly serious threat to the health of Indians. Air pollution control is an urgent problem to be addressed in India. In order to control air pollution, India has implemented the new emission standard for pollutants from coal-fired plants since January 1, 2017. To this end, the project was renovated to make particulate matter emissions from the coal-fired power plant meet the new emission standard, guarantee normal production of the Owners, and contribute to air pollution control of the local community.
