Description

Dry desulfurizier 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 dey oxidation.

Parameter

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.

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)

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.
