What is a hydrotreater?

A hydrotreater is a refinery that reduces sulfur and nitrogen while producing petroleum. Hydrotreating aims at producing cleaner fuels at affordable prices according to Shell Global.

Hydrotreating consists of using hydrogen to react with oil fractions. This process enables vehicles and trains to reduce emissions when using fuel during transportation, notes Shell Global. A reactor is used in the product of the fuel and the process is optimized depending on the customer and the intended use of the fuel. Shell Global is just one company that uses a hydrotreater to create cleaner fuel. This allows a company to meet the demands of cleaner fuel for users around the world.
