Hydrodesulfurization

Hydrodesulfurization is a catalytic process of removing sulphurous compounds from hydrocarbons the purpose of which is to reduce subsequent harmful emissions in downstream products Produced Sulphur goes on to make elemental Sulphur or Sulfuric acid for industry. The process is based on the Hydrogen displacement of Sulphur (by breaking the Carbon-Sulphur bond) at elevated temperatures and pressures in a catalytic bed usually based on Molybdenum and Cobalt. The vast majority of refineries with have a HDS unit sometimes known as a Hydrotreater a BIH fired heater upstream of the HDS unit conditions the stream for the catalytic process.
