Biogas biological desulfurization is a new technology developed in the 1990s, also known as biological catalytic desulfurization (BDS). It is a new technology that uses aerobic and anaerobic bacteria to remove bound sulfur from petroleum sulfur-containing heterocyclic compounds at normal temperature and pressure.

Biogas desulfurization - acid biological desulfurization process
盈和瑞酸法生物脱硫其反应方程式如下：
The reaction equation of Yinghe Rui acid biological desulfurization is as follows:
H2S+2O2 →H2SO4
H2S+2O2 →H2SO4
2H2S+O2 →2S+2H2O
2H2S+O2 →2S+2H2O

Dehydration, impurity removal and buffer process of biogas desulfurizer:
The pressurized biogas enters the buffer tank to realize the separation of gas, liquid and solid, so as to meet the stable gas supply to the generator unit and ensure the and operation of the generator unit. The separated water and particles are settled to the bottom of the buffer tank by gravity, and at the same time, the impurity gas partially dissolved in the water is discharged from the bottom of the buffer tank with the water. Purified gas enters the generator set from the top
