Vedanta Aluminium deploys IIoT technology in power plant to improve emissions control
Bhubaneswar, 17thApril 2023: Vedanta Aluminium, India’s largest producer of aluminium, has augmented its 2400 MW Thermal Power Plant with Industrial Internet of Things (IIoT) devices in fabric filters to improve emissions control. Fabric filters are special bag filtersplaced after electrostatic precipitators in chimneys to collect or particulate matter from the hot gas emanating from the power plant boiler system, stopping them from escaping into the atmosphere. The differential pressure between the bags plays a pivotal role in improving the efficiency of the filters. This is the 3rd line of defense in capturing particulate matter and gases, which significantly improves the air quality. The company has moved from the traditional way of measuring differential pressure through transmitters to using IIoT devices for precise monitoring and immediate action.
Customised applications of leading-edge technologies across the value-chain are helping Vedanta Aluminium exercise stringent control on operational parameters tobolsterESG (Environmental, Social & Governance) performance. This includes a laser focus on environmental parameters such as energy conservation, carbon reduction, air quality, water sustainability, circular waste management, and biodiversity.
Highlights of the company’s sustainability journey include:
· Reduced greenhouse gas (GHG) intensity (Scope 1 + Scope 2) from 19.3 tCO2e/MT in FY21 to 17.6 tCO2e/MT in FY22, which is the lowest amongst primary aluminium producers in India
- Launched first low carbon ‘green’ aluminium from India, branded Restora
- India’s largest industrial consumer of renewable energy at 3 Billion Units
- Signed Power Delivery Agreement for 380 MW of renewable power supply to aluminium smelters
- Reduced GHG emissions intensity by 24% in FY 2022, from 2012 baseline
- Commissioned India’s largest fleet of lithium-ion battery powered EV forklifts
