US-headed global process technologies provider Lummus Technology LLC has recently announced the successful start-up of its CDTaee unit for Hellenic Petroleum’s refinery in Aspropyrgos, Greece. For this start-up, the existing CDTame unit was revamped to the latest generation of CDTaee technology for bio-ethers production.

A part of Lummus Technology’s clean fuels technology portfolio, the new CDTaee unit will not only help Hellenic meet its biofuel requirements in Greece but also resolve blending constraints and produce a high-octane gasoline-blending component, TAEE (Tertiary Amyl Ethyl Ether).
Hellenic Petroleum has now started to use the TAEE product in its gasoline blends that it sells in its respective markets.
The start-up of our latest generation CDTaee technology is an excellent example of how Lummus offers innovative sustainability solutions to our customers. We help our customers such as Hellenic Petroleum produce cleaner fuels that are more efficient and perform at a higher level to meet stringent environmental standards, said Leon de Bruyn, President and CEO of Lummus Technology.
The latest generation of the CDTaee process is part of Lummus’ etherification technology portfolio, where the company has a leading position with over 140 references.
In the CDTaee process, TAEE is formed by the reaction of isoamylenes, which are present in light fluid catalytic cracking (FCC) naphtha, with bio-ethanol.
According to the company, the CDTaee process is unique in that extremely high isoamylene conversion can be achieved through proven, novel process design.
