Hydroprocessing has become an increasingly important refinery process.
Hydroprocessing in the refinery consists of hydrocracking and hydrotreating units that upgrade low value oil into cleaner, high value fuel products and reduce sulfur, nitrogren and aromatics in the hydrocarbon streams. With the growing demand for clean transportation fuels, flexibility in product yields, and a shift toward low sulfur diesel, hydroprocessing has become an increasingly important refinery process.
