Closing critical gaps to enable a circular plastics economy

Abstract

Global Petrochemicals, a leading manufacturer of basic chemicals and high-performance polymers, would like to satisfy consumer demands to reduce plastic waste via optimized engineering process designs and societal innovations. In order to fulfill their commitment of producing 10% of their plastics from recovered plastic waste, Global Petrochemical must design and invest in new process technology for Pyoil purification and plastic waste recycling facilities in Bali, Indonesia. To fulfil the outlined goals of Global Petrochemicals, a preliminary design of a Pyoil purification system was created to purify oil from pyrolyzed plastic waste. Fractionated products from the pyrolyzed oil were designed to meet specification requirements and be transported to an ethylene plant in Southeast Asia. Process safety and economic performance were considered when creating and optimizing the preliminary design. In addition to the preliminary design of a Pyoil Purification Unit, strategies for improving the efficiency and effectiveness of a manual sorting and collection facility in Bali, Indonesia were included in final process economics.
