China wholesale Desulfurization Vessel - Dry Desulfurization – Mingshuo

Dry desulfurization system is our company according to the user’s gas hydrogen sulfide (H2S) requires the use of periodic and related data made by professional design standardization, the actual content of gas desulfurization process, gas, tailored dimensions and internal structure, different types of gas, hydrogen sulfide content in different gas desulfurization equipment, the size of different gas pressure design the different, different internal structure. The desulfurization system is suitable for the gas with low hydrogen sulfide content, large processing capacity and high desulfurization precision, especially for prolonging the service life of the methane utilization equipment.

Biogas flows from one end of the desulfurization tower to the other end after being purified by a packed layer (mainly composed of activated carbon and iron oxide). Hydrogen sulfide reacts with iron oxide in the filler layer to form iron sulfide, which can be regenerated after the reaction.

Desulfurization principle:

Fe2O3· H2O+ 3H2S = Fe2S3+ 4 H2O

Regeneration principle:

Fe2S3 + 3/2 O2+ 3 H2O = Fe2O3 ·H2O + 2 H2O+ 3 S
