Energy Management

The ultimate goal of Energy Management is to control and reduce our organization's energy consumption. This is important because it enables us to reduce costs which is becoming increasingly important in view of increase in energy costs. We at IVL have a very strong focus of energy efficiency improvement, energy reduction which directly reduces our energy costs thus making us more competitive in the market and indirectly it helps in reducing GHG emissions for the products thereby going towards low-carbon economy.

There are multiple benefits from implementing Energy Management system. We can improve the energy efficiency of the machineries / equipment’s their by optimizing their consumption. This would indirectly reduce our utility bills and reduce carbon footprint for our products. IVL has undertaken several concurrent energy savings initiatives for transforming concept of Energy Management into practice through many of energy efficiency projects, which have been established and implemented in similar sites. We have implemented multiple energy efficiency projects saving over last few years. In 2022, we are further exploring options for reduction of energy intensity by conducting third party external audit in our plants for identifying hot spots for further energy reduction. External energy audit reports are being shared to business heads for their reviews and implementation in respective segments.

  • Intensities are calculated based on overall production including inter-company sales.
  • 2020 energy has increased as IVL acquired cracker plants, which resulted in higher energy consumption.
  • 2020 and 2021 environmental data has been restated using a more stringent definition and methodology.
  • 2020 baseline was adjusted for an alignment.

Case studies
Energy Savings Achieved in India

Indorama Ventures Oxides Ankleshwar Pvt Ltd (IVOAPL) has achieved a significant reduction in GHG emissions and energy use through various onsite energy savings initiatives by its Utility and Engineering teams. These initiatives resulted in a reduction of 585 tCO2e/year in GHG emissions and a decrease in energy consumption by 2,345 GJ/year. The company’s commitment to reducing energy use and improving operational efficiency was acknowledged at the National Energy Conservation Awards 2022, further supporting IVL’s Vision 2030 to become a global sustainable chemical company.

Propylene Purification Tower Steam Reduction

The IVOX Port Neches Team carried out studies to determine the impacts of bypassing the Propylene Recycle tower, by sending a portion of the propylene stream to the olefins unit tower for processing, with the remainder sent for recycling to Epoxidation. This project is expected to yield an energy reduction of 324,090 GJ/year along with an emissions reduction of 478 metric tons of CO2. The process efficiencies achieved from this project would lead for a total operational savings of US$ 2.6 million.

Non-GHG Air Emissions Programs

Beyond Compliance: Guangdong IVL PET Polymer Kaiping Limited, our wholly-owned subsidiary in China, has undertaken environmentally-friendly initiatives installing a nitrogen oxide (NOx) reduction system valued at over USD 230,000 to reduce NOx values beyond limits permitted by the government. This initiative has resulted in environmental, social and economic benefits which include:

  • Less NOx emissions in the air, much lower than permitted levels.
  • No solid or liquid contaminant is being generated or secondary pollution during operations.
  • Low running costs due to use of less expensive catalysts.
  • Easy to handle, transport and store as the new reducing agent is uninflammable and non-explosive.

Indorama Petrochem Limited (PET)’s plant in Rayong, Thailand, continues to demonstrate strong stakeholder engagement and significant process optimizations. At the end of 2019, the plant installed a stripping column to reduce the COD/BOD in wastewater prior to its delivery to a wastewater treatment plant. In addition, a catalytic incinerator was installed to remove any off-gas from the process. In 2020, electrostatic precipitators (ESPs) were used to replace the cyclonic separation process for particulate collection. This initiative reduced total suspended particulates by 91% and reduced the NOx emissions rate by 29%. These actions demonstrate IVL’s solutions that meet or exceed stakeholder expectations.

Waste Heat Recovery and Utilization

Optimizing our systems to reduce carbon emissions and energy consumption is integral to reaching our 5% energy intensity reduction by 2025. In support of these reductions, our Trevira Bobingen site in Germany has been utilizing waste heat exchangers. Heat generated by air compressors is recycled and used within the manufacturing process to preheat boiler feed water and finish dip baths. In 2020, This technology achieved an energy saving around 23,740 GJ and reduced carbon emissions of 1,360 tCO2e.
