Olgone technology removes olefins from aromatics streams; promises to be cleaner than clay treaters
ExxonMobil Chemical Technology Licensing has moved to commercialise its Olgone technology, a method of removing olefins from aromatics streams.
Olgone is a catalyst-driven technology that provides aromatics plant operators with an alternative to the clay treaters currently used to reduce olefin content.
According to ExxomMobil, Olgone is more effective than clay treaters in removing olefinic materials that can interfere with downstream equipment, adsorbents, sieves and catalysts.
Olgone technology could help reduce costs, control solid waste and improve operational efficiency.
The technology can apparently be retrofitted into existing clay treaters and operates at the same process conditions.
“We’ve been using the process in our own aromatics plants for a number of years and are extremely pleased with its superior performance,” says David Starkey, global xylenes licensing manager, ExxonMobil Chemical Technology Licensing.
“It is going to be especially welcome news for plant operators who are now struggling with very short clay treater cycles or wish to expand throughput.
Olgone provides a way to de-bottleneck without the large capital investment of adding new clay treater vessels.”
Olgone apparently uses the same basic chemistry as conventional clay systems to remove olefins, but its processing capacity is 4 to 6 times that of clay, due to a proprietary catalyst system engineered for low-temperature alkylation reactions.
The Olgone catalyst offers improved environmental performance as it is regenerable, unlike the clay that it replaces.
ExxonMobil Chemical Technology Licensing is an arm of ExxonMobil Chemical, a worldwide petrochemical company that manufactures olefins, aromatics, fluids, synthetic rubber, polyethylene, polypropylene and many other kinds of petrochemical products.
ExxonMobil Chemical Technology Licensing develops and licenses methods and techniques discovered in the company’s manufacturing activities.
Its technology offerings span the entire petrochemical and polymer sectors.
