Aromatics Treatment Process Hydrocarbon Processing

2018-6-3  Aromatics Treatment Process To reduce olefinic content in either a heavy reformate feed or an aromatic extract feed using ExxonMobil Chemical’s Olgone process. Olgone is an alternative solution to clay treating that is used to reduce olefins content and thus, lower the Bromine Index (BI) of heavy reformate and aromatic extract streams.
