Development Of Desulphurization And Dearsenication Craft Under Vacuum For Ferrotungsten

Desulfurisation is a chemical process for the removal of sulfur from a material. This can involve either the removal of sulfur from a molecule (e.g. A=S → A:) or the removal of sulfur compounds from a mixture such as petrochemicals or flue gases.

Many of these processes are of great industrial and environmental importance as they provide the bulk of sulfur used in industry (Claus process and Contact process) and also reduce the release of harmful sulfur compounds into the environment (hydrodesulfurization, flue-gas desulfurization); particularly sulfur dioxide (SO2) which leads to acid rain.

It introduces crafts and related factors of desulphurization and dearsenication craft under vacuum for ferro-tungsten. By adapting to the craft, the average arsenic content in ferrotungsten can reach 0. 0352% , the average sulfur content in alloy can reach 0. 0152%, the average dearsenication ratio and desulphurization ratio can reach 27% and 76% respectively.
