Refinery Hydrotreating Units

Refinery hydrotreating units are the purification workhorses of a modern refinery, reacting petroleum fractions with hydrogen over a catalyst to remove sulfur, nitrogen, oxygen, and metals. Their output is the cleaner, more stable fuel that current environmental standards demand.

What Hydrotreating Removes

Sulfur compounds convert to hydrogen sulfide, nitrogen to ammonia, and oxygen to water, each leaving the feed as a manageable by-product. Removing these impurities prevents corrosion, protects downstream catalysts, and keeps finished fuels within regulatory limits.

Units for Every Distillate

Naphtha hydrotreating units prepare feedstock for catalytic reforming, while diesel hydrotreaters produce ultra-low-sulfur diesel with sulfur below the tightest limits. Full-range units flex across naphtha, kerosene, and diesel for refineries with varied slates.

Hydrogen, Catalyst, and Separation

Feedstock is preheated, mixed with hydrogen, and passed over a cobalt-, molybdenum-, or nickel-based catalyst bed. Cooled effluent is separated from by-product gas, and recycled hydrogen returns to the loop, improving efficiency and lowering operating cost.

Cleaner Fuel, Longer Equipment Life

Refinery hydrotreating units extend equipment life by preventing fouling and corrosion while producing fuels that cut sulfur and nitrogen oxide emissions. Klean Industries designs and delivers the hydrotreating systems that keep a refinery compliant and competitive.
