1200 BPD Benzene Removal System

REFINERY  |  MIDWEST US

Problem 

Client had a reformate stream with benzene which needed to be removed prior to downstream processing.

History

The company needed to add distillation capacity at their plant to remove benzene from reformate prior to gasoline blending in their facility.

Solution

The client requested that ChemPro design a continuous distillation system that would remove benzene to upgrade distillates for further blending downstream at their plant. The unit needed to handle a range of feedstock variability. ChemPro conducted extensive process simulations to ensure the system could handle the varying feed, operate reliably throughout the feed range and minimize product losses. ChemPro designed, engineered, and built a modular continuous distillation system. The unique design included a complex control scheme to ensure the system could operate over a range of feed rates and compostions, respond quickly to upsets while maintaining product purities and energy efficiency.

Results

The unit has met all process criteria, increased production capacity and conforms to the product requirements for production.
