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.
