The BenzOUT process is a commercially proven technology for benzene reduction in gasoline. BenzOUT converts benzene, typically in a light reformate stream, to higher alkylaromatic blending components by reacting a benzene rich stream with light olefins, such as a refinery grade propylene stream.
BenzOUT technology avoids octane loss with no hydrogen consumption associated with beneze saturation alternatives by alkylating propylene to the aromatic rich stream. BenzOUT can be a grassroots unit or retrofitted into an existing facility, such as a polygas unit. The technology was developed by ExxonMobil and is available for licensing through Badger Licensing LLC to provide a unique process advantage to help refiners meet benzene regulations, while at the same time achieving an attractive economic return on their investment.
Key Benefits:
Low Operating Costs
Low temperature pressure liquid phase process
No hydrogen consumption
Simple, fixed bed reactor
Volume Swell
Deep conversion of reformate stream benzene
Gasoline volume swell
High Octane
Octane increase in the full reformate
BenzOUT technology advantages and economical benefits
Conversion of 95%+ of the benzene in a reformate stream: highly selective and stable catalyst enabling the process to run at a very high benzene conversion to meet EPA Mobile Source Air Toxics (MSAT) regulations
Low temperature liquid phase process
Octane increase: 2-3 numbers of (research octane number + motor octane number)/2 gain in a full reformate, depending on the feed composition
No hydrogen consumption: refineries could feed all the C8 components (low blending octane values) to the reformer unit to achieve increased hydrogen production and octane gain
Gasoline volume swell: upgrading of light olefins and benzene into high-octane alkylaromatic blendstock would also result in a volume swell of the gasoline pool
