Axens (Rueil-Malmaison, France) and Hyundai Chemical Co. successfully started up a new pyrolysis gasoline (Pygas) unit, part of the Hyundai Chemical petrochemical grassroots complex in Daesan, South Korea. The product has been on-specification regarding the aromatics recovery and the sulfur content in a short period.
Thanks to the strong support of Axens personnel on-site during the commissioning and start-up activities, Axens and Hyundai Chemical, started-up the Pygas units (Pygas first and second stage) in December 2021, few months after entering into a collaboration.
Since the first steps of the project, Axens and Hyundai Chemical Co. worked in close collaboration with the aim of optimizing the process scheme, thus achieving lower energy consumption on the Pygas first stage and less investment in equipment for the Pygas second stage while allowing South Korea to increase even more its ethylene production.
