Sulphur in Steels – IspatGuru

Sep 23, 2014· Sulphur in Steels. Sulphur (S) (atomic number 16 and atomic weight 32.066) has density of 2.05 gm/cc. Monoclinic S melts at 119.25 deg C and boils at 444.6 deg C. However, S and iron (Fe) are miscible, and Fe-S binary system at one atmosphere of pressure forms a liquid at temperatures as high as 1800 deg C, far above the boiling point of S alone.

Hydrodesulfurization - Wikipedia

Hydrodesulfurization (HDS) is a catalytic chemical process widely used to remove sulfur (S) from natural gas and from refined petroleum products, such as gasoline or petrol, jet fuel, kerosene, diesel fuel, and fuel oils. The purpose of removing the sulfur, and creating products such as ultra-low-sulfur diesel, is to reduce the sulfur dioxide (SO 2) emissions that result from using those fuels ...

How do I remove sulphur smell after passivation of 303SS?

303 stainless steel contains sulphur and therefore sulfides. When treated in acid, the sulfides are decomposed to form sulphurous gases. To avoid the smell, try dipping the workpiece in dichromate; this will oxidise the sulphurous material and reduce the dichromate to trivalent chromium. Trevor Crichton R&D practical scientist Chesham, Bucks, UK
