Iron sponge has been used to remove H 2 S from gas streams for more than 100 years and the media is comprised of wood chips coated with iron hydroxide. H2SPlus Systems are currently in use throughout the U.S. treating a variety of gas streams to remove H 2 S & mercaptans and reduce SO 2. View Case Studies. How It Works
Part 3A: Iron Sponge Basics November 2017 One of the oldest technologies for the removal of hydrogen sulfide (H 2 S) from gas is the use of "Iron Sponge". A chemicalphysical process, originally developed to remove H 2 S from natural and coal gas streams, iron sponge has been in use for over 140 years and more recently to remove H 2
Commercial sponge iron powder production dates back to 1903 with the invention of the Sieurin process in Sweden. Since 1911 the Hoganas Corporation has continuously manufactured sponge iron, although the early use for this product was as a feedstock for steel making.
The pellets produced by Xindia will er, both to the domestic iron and steel industry and also to burgeoning export markets in China, Japan, Korea, which are largely dependant on imported Iron Ore to feed their blast furnaces and DRI(Sponge Iron) kilns.
