H2S Biogas Purification Equipment 10ppm Wet Flue Gas Desulfurization

Biogas Purification Wet Desulfurization System For Oxidation Reduction

Biogas Purication Equipment Description:

Dry desulfurization is a simple, efficient and relatively low-cost desulfurization method. It is generally suitable for desulfurization of biogas with low biogas and low hydrogen sulfide concentration. The basic principle of the dry process for removing hydrogen sulfide (H2S) from biogas gas is a method of oxidizing H2S to sulfur or sulfur oxide by O2, which is also called dry oxidation.

Dry desulfurization equipment can used in the purification system of biogas, farm, starch, papermaking, sewage treatment, alcohol, chemical fiber, pharmacy, fertilizer, coking, landfill, coal gas, natural gas, ceramics, food, maize further processing, citric acid, and other industries.

Biogas Purication Equipment Advantage:

1. Easy to install and easy to use.
2. During the work process, no personnel are required to be on duty, and the materials are renewed regularly.
3. The desulfurization efficiency is high, and the effect of recycling can be achieved by oxidation reduction in the later stage.
4. Fine desulfurization, high precision of desulfurization.
5. Initially low investment and medium operating costs.

Biogas Purication Equipment Working Priciple:

First step: Fe2O3 · H2O + 3 H2S = Fe2S3 + 4 H2O (desulfuration)

Second step: Fe2S3 + 3/2 O2 + 3 H2O = Fe2O3 · H2O + 2 H2O + 3 S (regeneration)

The main composition of desulphurizer is ferric oxide (Fe2O3).
After some time of use, Fe2O3 will lose its effectiveness ( you can find that there is bad smell when using biogas). In this case, you must replace the Fe2O3 in time.

Biogas Purication Equipment Application:

It is mainly used for the removal of corrosive hydrogen sulfide (H2S) gas in biogas, and can also be used for other purification of hydrogen sulfide gas, so that the treated gas provides safety for the normal use and service life of the required equipment.
