PRESS RELEASE: Koch Partners, LP To Build Diesel Hydrotreater And Crude Oil Distillation Unit

Project to aid Wynnewood in meeting operational and environmental goals

TYLER, Texas – Koch Partners, LP will design and build a 20,000 bpsd diesel hydrotreater and a crude oil distillation unit for Wynnewood Refining Company in Wynnewood, Okla. The project, to be executed through an engineering, procurement and construction (EPC) contract, is expected to be completed in spring 2007.

Koch Partners, an affiliate of Koch Chemical Technology Group Inc., will provide process design, detailed engineering, project management, procurement, fabrication and field construction services for Wynnewood, a subsidiary of Gary-Williams Energy Corporation.

The diesel hydrodesulfurization unit will utilize open art technology and is designed to produce naphtha, mineral spirits, jet fuel and ultra-low sulfur diesel (ULSD). The new crude oil distillation unit will allow the refinery to increase crude capacity and process a heavier, more-sour crude slate. The scope of supply for the new crude processing unit includes a new vacuum distillation unit, as well as modifications to existing facilities.

When complete, the project will provide Wynnewood with additional refining capacity and operating flexibility for crude supply and distillate production, while balancing performance and economic objectives. The project is also a key component of the company’s overall strategy for clean fuels.
