hydrodesulfurization
Refinery cleaning process
Hydrodesulfurization is a chemical process that removes sulfur from petroleum and natural gas by treating them with hydrogen at high temperatures and pressures.
The process is essential in refining fuels to meet environmental standards and reduce sulfur dioxide emissions when the fuel is burned: The refinery upgraded its hydrodesulfurization unit to produce ultra-low-sulfur diesel.
