5000 BPD ULSD Diesel Hydrotreater

TRANSMIX TERMINAL COMPANY  |  MIDWEST US

Problem  

Client had to meet ultra low sulfur diesel (“ULSD”) spec at their location for resale into the market.

History

The company needed to add hydrotreating capacity at their plant to meet the latest market demands.

Solution

The client requested that ChemPro use a third-party technology company to design and build a low sulfur diesel hydrotreater for their facility. The unit needed to meet the ultra low sulfur spec for ULSD diesel. ChemPro designed, engineered, and built a modular diesel hydrotreater using the basic engineering package provided by the client through a technology company. The unit was integrated into their existing transmix facility to improve heat integration and reduce plot size and overall project costs.

Results

The unit has met all process criteria and after some additional upgrades exceeds capacity output.
