Honeywell UOP providing hydrotreating catalysts for ENAP refinery in Chile

DES PLAINES, Ill. — Honeywell announced that Empresa Nacional del Petroleo (ENAP) has begun using Honeywell UOP’s HYT-6219 Unity hydrotreating catalyst in conjunction with Unity hydrocracking catalysts to produce cleaner-burning diesel fuel at its Bío Bío refinery in Hualpen, Chile.

The HYT-6219 catalyst pretreats the petroleum feed used to make diesel fuel, removing sulfur, nitrogen and aromatics that would otherwise hurt the performance and longevity of hydrocracking catalysts later in the refining process. The refinery also uses Honeywell UOP’s HC-130 and HC-120 Unity hydrocracking catalysts as part of its production process.

Hydrotreating is a critical step in the refining process where hydrogen and a proprietary catalyst are used to pretreat petroleum and other products by removing contaminants before conversion into transportation fuels. The process helps produce cleaner-burning gasoline and diesel that meet increasingly stringent global fuel regulations such as the Euro V standard, which specifies sulfur content of less than 10 parts per million in transportation fuels.

Honeywell UOP’s line of Unity catalysts includes more than two dozen hydrotreating catalysts for hydrocracking and fluid catalytic cracking (FCC) pre-treat, and diesel, kerosene and coker naphtha hydrotreating. Honeywell UOP also offers catalysts for naphtha hydrotreating and FCC gasoline desulfurization. The Unity portfolio is a total solution for hydrocracking loads.

According to the International Energy Association (EIA), global demand growth for transportation fuels is shifting toward emerging economies with a diesel bias, while quality specifications for international marine fuels will drive a shift from residual fuel oil to marine diesel. Trucks, which are a key enabler of commercial activity in emerging economies, will lead to a significant increase in carbon dioxide emissions of nearly 900 MMt through 2050, heightening the need for cleaner-burning diesel fuels.

ENAP is a public commercial enterprise owned by the State of Chile whose main activity is the exploration and production of hydrocarbons through its subsidiary Enap Sipetrol SA and the refining, transport, storage and commercialization of petroleum products through Enap Refinerías SA. The company develops activities and operations in Chile, Argentina and Egypt and is headquartered in Santiago de Chile.
