Thyssenkrupp makes methanol from steel mill gases for the first time
Steel and smelting works produce large quantities of process gases, so-called steel mill gases. They contain many valuable chemical elements, from which Thyssenkrupp is now winning back methanol.

According to
Steel mill gases consist of carbon compounds, among them carbon dioxide (CO2), nitrogen and hydrogen. So-called synthesis gas can be produced from these compounds and can then furnish the basis for the production of various chemicals such as ammonia, polymers and even methanol. This also relieves the burden on the environment: not only is the environmentally harmful CO2 that escapes during steel production converted into a recycled material, so is the CO2 that until now has been created when producing synthesis gas from carbon carriers.
The procedure has now been tested in a pilot plant. The demand is there, according to Thyssenkrupp: Around the world there are around 50 steel works that could be considered for the Carbon2Chem project. Moreover, the process is applicable to other industries.
