(147a) Process Solutions for Improving the Stability and Handling Properties of Pyrolysis Oils
Nalco Water has been and continues to be deeply involved with both producers and users of pyrolysis oils as we work with these customers to understand the challenges presented by these streams and develop potential solutions. Over the course of this work, key areas of concern have been identified, including cold flow handling behavior and stability (particularly with regards to the formation of sediment, gums, and/or films). Treatment with various chemical additives provides customers with options for addressing these challenges and improving the overall properties and performance of the pyrolysis oil stream.
Here we will provide a discussion of broad industry trends around chemical recycling (with particular focus on PE and PP recycling), initial findings around the challenges associated with pyrolysis oils, and chemical treatment options that can be considered and have been demonstrated at lab scale.
