Plastic pyrolysis oils as feedstock for steam crackers: Opportunities and challenges—Part 2
Plastic waste is a worldwide challenge. To reduce its carbon dioxide (CO<sub>2</sub>) footprint, the plastics industry is striving to increase circularity by using plastic pyrolysis oils (pyoils) from waste plastics as steam cracker feedstock.
Practical examples and considerations in designing emergency depressurizing systems
Process operating facilities typically process large inventories of gas and volatile hydrocarbon liquids at high pressures, which have the potential of posing major hazards during emergency incidents—such as fire, loss of containment or operating excursion.
Plastic pyrolysis oils as feedstock for steam crackers: Opportunities and challenges—Part 1
Plastic waste is a global challenge. Today, only a minimal amount of plastic waste is recycled, mostly mechanically.
