Advanced Recycling for Plastics

Approximately 350 Million Metric Tonnes of plastic waste are generated annually around the globe, and companies in related industries have committed nearly $1.5 billion to reduce this figure. Nalco Water supports Advanced Recycling methods for plastic waste, such as pyrolysis and other chemical recycling technologies. Government regulations, consumer behavior, and industry emphasis on sustainability are driving unique solutions to provide alternative feedstock for ethylene production. 

Nalco Water is uniquely positioned to identify, diagnose and treat process and utility-related problems at advanced recycling plants, and to handle storage, transport, and processing needs for the ethylene industry or other downstream processors. Our innovative, long-term solutions help optimize operational efficiency, maximize asset reliability and profitability, all while maintaining safety, health, and environmental compliance.

Process Solutions for Pyrolysis Oils

Enhance Product Stability 

Advanced Recycling methods for plastic waste usually create oil-fractions (Pyoil) high in olefinic and diene content, making these products prone to tars, films, and sediment formation. Our innovative and patent-pending extraction and stabilizing solutions effectively remove film- and tar-forming compounds to not only enhance the short- and long-term storage stability, but also make these Pyoils fit for cracking in ethylene furnaces.

Improve Cold Flow Properties 

Continued and reliable operations during winters is critical for any process plant. Many Pyoils demonstrate poor and variable cold-flow properties depending on the plastic waste stream components and different advanced recycling technologies. Nalco Water’s patented EVA-copolymer-based flow improvers ensure optimized flow behaviors in all seasons, eliminating the costly alternative of heat-tracing process equipment and transfer pipelines. Our products are also certified safe for ethylene furnaces.

Optimize Acidic Corrosion 

The Pyoils manufactured by Advanced Recycling methods contain high acidic components, generally coming in through PVC waste and other metallic impurities, and hence demonstrate high TAN figures. The acidic nature of these streams poses significant corrosion threat not only to chemical recycling plants but also to ethylene plants that would eventually process Pyoils in their furnaces. Nalco Water’s optimized neutralizer programs and online chloride monitoring capabilities give valuable insights and control over potential acidic corrosion.
