Product Description

Chemical Method for Hydrogen Sulfide Removal from Biogas

Desulfurization is a chemical process for the removal of sulfur from a material. This involves either the removal of sulfur from a molecule (e.g. A=S → A:) or the removal of sulfur compounds from a mixture such as biogas, methane and oil refinery streams. These processes are of great industrial and environmental importance as they provide the bulk of sulfur used in industry, sulfur-free compounds that could otherwise not be used in a great number of catalytic processes, and also reduce the release of harmful sulfur compounds into the environment, particularly sulfur dioxide (SO₂) which leads to acid rain, and hydrogen sulfide (H₂S) which leads to poison, even death.

Purpose of Desulfurization
Biogas, natural gas, coke oven gas, semi-water gas, petroleum associated gas and waste water contain hydrogen sulfide which is poisonous. Hydrogen sulfide can seriously corrodes equipment and pipelines. Inhalation of trace amounts of hydrogen sulfide can cause disability and endanger life. Therefore, hydrogen sulfide must be removed before it can be used as a clean energy source.

Dry desulfurization system is kind of standard equipment we designed and produced. According to the content of H₂S in gas, the actual content of gas, the life cycle of absorbent, and other relevant data, we will specially design the system structure for customers. If you have fixed the dimensions and internal structure, we're also able to manufacture it according to your design drawings.

For real-time monitoring the reaction speed of sulfide and the oxygen in air in the process of regeneration, we added temperature monitoring equipment, this can avoid accident fires in the process of regeneration.(When the content of the entered air gets too large, the exothermic reaction will be violent, and the temperature will be above the sulfur's ignition point, which will lead to accidental fires.) Or you can simply get the absorbent outside the tank, and let it regenerate in the air. 



Working principles
Fe₂O₃ · H₂O+3H₂S=Fe₂S₃ · H₂O+3H₂O
2Fe₂S₃ ·  H₂O+3O₂ = 2Fe₂O₃ ·  H₂O+6S

Performance and characteristics
1. Simple structure, low investment, long lifetime
2. Easy to manage, reliable operation, dispense with staff on duty, refueling at fixed period, one use one reserve, alternate operation
3. Compared with wet method, need refueling at fixed period
4. High efficiency, applicable to small and medium projects with gas less than 5000m³/day, high precision of desulfurization (lower than 15ppm)


Application:
This dry desulfurization equipment can be used in biogas, livestock farms, starch, papermaking, sewage treatment, alcohol, chemical fiber, pharmaceutical, fertilizer, coking, landfill, gas, natural gas, ceramics, food, corn deep-processing, citric acid and other industries in the purification system.
