Product Description
This dry desulfurization system is a standardized biogas purification process specially designed and manufactured by our company according to the H2S content in biogas, the required service life span and other relevant data. The dimensions and internal structure of desulfurization equipment vary with the type of gas, gas pressure and hydrogen sulfide content. The desulfurization system is particularly suitable for the gas with low hydrogen sulfide content, small processing capacity and high desulfurization precision. What's more, it can effectively prolong the service life of the methane utilization equipment
Management System Certification: ISO9001:2008, ISO14001:2004, OHSAS18001:2007
Principle:
The basic principle of dry desulfurization is a method of oxidizing H2S to elemental sulfur or sulfur oxides by oxygen. The other method is the special iron oxide absorption method (MT series special iron oxide desulfurizer), that is, the active ferric oxide in special iron oxide desulfurizer is used to absorb hydrogen sulfide in the gas and convert it into ferric sulphide, thus removing hydrogen sulfide (at present, this method is mostly used). The composition of the dry process equipment is that a filler is filled in a tank, and the filler layer can be iron oxide desulfurizer, activated carbon desulfurizer, etc. It is better to use iron oxide desulfurizer, so the sulfur content of desulfurizer is large and the cost is low. At a low velocity, the gas passes through the packing layer of the tank from one end, and the hydrogen sulfide is oxidized to sulfur or sulphur oxide or converted to iron sulfide. The gas is left in the packing layer and the gas is discharged from the other end of the container.
Fe2O3 · H2O+3H2S=Fe2S3 · H2O+3H2O
2Fe2S3 · H2O+3O2 = 2Fe2O3 · H2O+6S
Characteristics of Dry Desulfurization :
1. The structure is simple and easy to use.
2. No duty is required in the work process, and regular replacement is done alternately.
3. The desulphurization rate was higher when the new raw material was used and later decreased.
4. Compared with wet type, it needs add desulfurizer regularly.
5. Higher operation cost.
Application of Dry Desulfurization:
Dry desulfurization equipment can be used in the purification system of biogas, animal husbandry, starch, papermaking, sewage treatment, alcohol, chemical fiber, pharmaceutical, chemical fertilizer, coking, landfill, gas, natural gas, ceramics, food, deep processing of corn, citric acid industry and so on.
According to the amount of hydrogen sulfide imported by the user, the amount of gas treated per hour and the cycle required by the user, the tailored desulfurization tank (or desulfurization tower), gas water separator, flame arrester, blower, pressure stabilizer, desulphurizer, water seal, pressure meter, flow meter and matching pipe valve can be designed.
Comparison: (Dry Desulfurization,Wet Desulfurization & Biological Desulfurization)
| Type | Initial Investment | Operating Cost | Management and Maintenance | Application |
| Dry Desulfurization | Lower | Replacement cost of desulfurizer, medium | Frequent replacement of desulfurizer and potential corrosion of tower | Fine desulphurization is suitable for small gas flow and low concentration of hydrogen sulfide. |
| Wet Desulfurization | Medium | Consumption of drugs is high. | Automatic control, Manual labor is needed to add the drugs | It is suitable for intake gas with large methane flow and high hydrogen sulfide concentration. Intake concentration above 20000ppm |
| Biological Desulfurization | Medium | Cheapest, less than 2 cents for each biogas treatment. | Fully automated operation, simple maintenance. | Most suitable for medium-scale biogas desulfurization (200-2000 Nm³/h, initial concentration of hydrogen sulfide in 2000 - 10000 ppm) |
