Delek US Holdings has initiated litigation against Marex Group and BTX Energy, alleging that a batch of contaminated crude—supplied via BTX’s terminal—caused at least $30 million in damage to one of its refineries. The contamination involved organic chlorides far above permissible limits, which damaged the Heavy Naphtha Hydrotreater unit and forced the disposal of ~300,000 barrels of processed product.

The dispute is currently lodged in Texas state court, with Marex already requesting transfer to a federal district. Delek’s claim accuses the suppliers of breach of contract and seeks recovery of repair and operational losses.

This case highlights ongoing feedstock risk in refining operations—where one bad crude batch can ripple into equipment failures, processing delays, and contaminated product inventories. As refineries tighten margins, improved due diligence, stricter crude quality controls, and contractual safeguards become more critical.
