success of Dynocel 680 hybrid adsorbent in PCK’s dryers, the refinery has reordered Evonik’s hybrid adsorbent, and it continues to be used in its operations today. “The change- out was a full success and we are very happy with its per - formance,” said Steffen Görlich, the responsible process engineer at PCK Refinery. Conclusion As has been demonstrated, selecting the proper adsorbent in olefin purification treatment is critical to ensure the effec - tive removal of all contaminants. However, on top of that, the impact of adsorbent properties should be considered from
a safety, reliability, and predictability standpoint to protect people, profits, and the environment. Florence Pennetreau is a Technical Business Manager at Evonik in Luxembourg. She holds a PhD in chemistry from UCLouvain University in Belgium, with a specialisation in catalysis. Todd Burkes is a Senior Product Manager at Evonik. He has more than 30 years of experience in adsorbents and catalysts, and holds a chemi- cal engineering degree from Texas Tech University. Steffen Görlich is a Senior Process Engineer in the FCC group of PCK’s Tech Service. He has more than 15 years of experience in FCC operation and its downstream units, including ETBE, TAEE, and HF alkylation. He holds a diploma in chemical engineering from Technical University Berlin.
