Low Energy Transmix Distillation

TRANSMIX TERMINAL COMPANY  |  SOUTHEASTERN US

Problem  

Client had a fast track production capacity need to fractionate a gasoline/diesel stream stored in terminal tanks at their location for resale into the market.

History

Local market conditions for processing transmix feeds became available for a terminal facility owner. The company needed to add distillation capacity at their plant to meet the latest market demands.

Solution

The client requested that ChemPro design a low energy continuous distillation system that would separate fuel oil and gasoline into resalable products. The unit needed to improve energy usage and have a 2 to 1 turndown range in capacity.

ChemPro designed, engineered, and built a modular continuous distillation system, incorporating several unique equipment designs to reduce energy usage by 40-50% compared to existing transmix distillation designs. The unique design included a multi-effect heat integration and reclamation step, which can also be a stand alone add-on feature for existing transmix fractionation units.

Results

The unit has met all process criteria and energy usage requirements.
