Case Study - TROMMEL Floating Drum Oil Skimmer in Action at NTPC - India's largest thermal power plant.

This case study highlights the successful deployment of Vens TROMMEL Floating Drum Oil Skimmer at NTPC and its impact on operational performance, environmental compliance, and maintenance efficiency. NTPC (National Thermal Power Corporation), India's largest power generation company, operates a range of thermal power plants across the country. These plants require innovative solutions to tackle oil contamination in their cooling water and other industrial systems. Partnering with Vens Hydroluft, one of India's leading manufacturers of oil skimmers, NTPC implemented the Vens TROMMEL Floating Drum Oil Skimmer to enhance operational efficiency and sustainability.

The Challenge

NTPC thermal power plants generate electricity by burning fossil fuels such as coal, oil, and gas. As a byproduct of this energy production, oil contamination is a common issue, especially in cooling water systems, storage tanks, and effluent treatment plants (ETPs). The oil contaminants, if left untreated, can lead to several problems:

  1. Environmental Impact: Oil spills into water bodies can severely harm aquatic life and ecosystems.

  2. Operational Inefficiency: Oil contamination can reduce the effectiveness of cooling systems, causing machinery to overheat and increasing the risk of breakdowns.

  3. Maintenance Costs: Frequent shutdowns for cleaning oil spills increase maintenance costs and downtime.

  4. Regulatory Compliance: Non-compliance with environmental norms can result in penalties and damage NTPC's reputation as a sustainable energy producer.

To address these challenges, NTPC sought an effective oil skimming solution that would be reliable, durable, and capable of handling large volumes of oil contamination across multiple plants.


The Solution: Vens TROMMEL Floating Drum Oil Skimmer

NTPC collaborated with Vens Hydroluft, a Chennai-based leader in the design and manufacture of oil skimmers, to deploy the Vens TROMMEL Floating Drum Oil Skimmer across their thermal power plants. The TROMMEL oil skimmer was chosen due to its robust design, high efficiency, and ability to work in harsh industrial environments.


Key Features of Vens TROMMEL Floating Drum Oil Skimmer:

  1. High Efficiency: The skimmer is designed to efficiently remove floating oil from the water surface, with a recovery rate of up to 98%.

  2. Durability: Built with corrosion-resistant materials, the skimmer is capable of functioning in highly polluted water environments, making it ideal for NTPC’s operational needs.

  3. Floating Drum Design: The floating drum design ensures the skimmer adapts to changing water levels, which is crucial in a dynamic industrial environment like a thermal power plant.

  4. Low Maintenance: The skimmer requires minimal maintenance, reducing operational downtime and maintenance costs for NTPC.

  5. Eco-Friendly Operation: The device allows NTPC to recover spilled oil, reducing environmental impact and allowing for recycling of the recovered oil.


Deployment at NTPC

NTPC's power plants, such as those in Korba (Chhattisgarh) and Singrauli (Uttar Pradesh), which face significant challenges due to oil contamination, were identified as prime locations for deploying the Vens TROMMEL Floating Drum Oil Skimmer. The installation process involved integrating the skimmers with the plants' existing effluent treatment and cooling water systems.

Vens Hydroluft provided comprehensive support during the deployment, including installation, operator training, and after-sales service to ensure smooth operation. The skimmers were strategically placed in areas where oil accumulation was most severe, such as cooling water outflows, oil storage tanks, and water treatment facilities.


Results & Impact

The deployment of Vens TROMMEL Floating Drum Oil Skimmers at NTPC has yielded significant benefits across multiple domains:

  1. Improved Operational Efficiency: The skimmer efficiently removes oil contamination, ensuring the cooling water system operates at optimal efficiency. As a result, NTPC has experienced fewer breakdowns and lower energy consumption.

  2. Reduced Environmental Impact: By preventing oil spills from reaching nearby water bodies, the skimmers have helped NTPC significantly reduce its environmental footprint. NTPC has been able to recover large quantities of oil, reducing the risk of pollution and enabling recycling of the collected oil.

  3. Cost Savings: The reduction in oil contamination has minimized the need for frequent cleaning and maintenance of equipment, leading to substantial cost savings for NTPC. The lower downtime has also contributed to enhanced productivity and power generation capacity.

  4. Regulatory Compliance: NTPC has been able to consistently meet environmental standards and avoid penalties by reducing the oil discharge into surrounding water bodies. The use of the Vens TROMMEL skimmer aligns with NTPC’s commitment to sustainability and responsible energy production.

  5. Long-Term Sustainability: The skimmers’ low maintenance requirements and long service life ensure that NTPC will continue to benefit from the solution for years to come. The technology also enhances NTPC’s ability to meet its long-term sustainability goals by reducing oil waste and promoting cleaner water management.


Conclusion

The successful implementation of the Vens TROMMEL Floating Drum Oil Skimmer at NTPC showcases the impact of advanced oil skimming technology in the energy sector. Vens Hydroluft's innovative solution has not only improved operational efficiency and reduced environmental impact but has also contributed to significant cost savings for NTPC.


As India’s largest thermal power producer, NTPC's adoption of this technology sets a benchmark for other power plants and heavy industries across the country, promoting sustainable practices in oil spill management and water treatment. The partnership between NTPC and Vens Hydroluft underscores the importance of local expertise and innovation in addressing the complex challenges of industrial operations.

Through this case study, it is evident that the Vens TROMMEL Floating Drum Oil Skimmer is a crucial tool in helping NTPC achieve its operational, environmental, and financial goals while maintaining a commitment to sustainability and environmental stewardship.
