biogas purification equipment,
h2s removal system
Large scale biogas plant Chemical desulphurization system/ H2S purification
Why we need desulphurization
Removal of H2S is often required for reasons of health, safety, environment and corrosion of equipment such as gas engines, boilers and piping. Desulphurization is also is necessary when biogas is upgraded to natural gas quality and injected in the grid.
Iron Oxide Desulfurizer is made of iron,manganese salt and their oxide as raw material,pass through the process chemosynthesis to be active oxide,then add the assistant and binder to make it columnar solid .
It has features of larger sulfur capacity ,small resistance,high purification capacity and good water resistance .

3.Desulfuration and Renewal Principles of the ferric oxide
Desulfuration Reaction: Fe2O3.H2O+3H2S=Fe2S3.H2O+3H2O
Renewal Reaction: 2Fe2S3.H2O+3O2=2Fe2O3.H2O+6S (strong exothermic reaction)
