Biogas fermentation project H2S gas absorption tower for biogas purifier

Biogas fermentation project H2S gas absorption tower
  Biogas fermentation project H2S gas absorption tower for biogas purifier include 2 desulfurization methods: Wet type desulfurization and Dry type desulfurization.
  Wet desulfurization  1. Wet type desulfurization   Product introduction Wet type desulfurization uses the absorbing agent NaOH, Ca(OH)2 or Na2CO3 to react with H2S, and translate H2S into sulphur.
The technology of desulphurization, regeneration, sulfur melting or filter processing has the advantage of being efficient and simple, easy to manage, and low cost of operation.   The main equipment Biogas plant wet type H2S removal system includes these main equipments:

No.	Equipment Name	No.	Equipment Name
1	Cooling tower	7	Rich liquid trough
2	Spray desulfurization tower	8	Solution preparation tank
3	Padding desulfurization tower	9	Roots blower
4	Regeneration tank	10	Regeneration pump
5	Sulfur foam tank	11	Desulfurization pump
6	Recycle tank

  Working principle 1. Alkaline solutions absorb H2S: Na2CO3+H2S==NaHS+NaHCO3 NaHCO3+H2S==NaHS+H2CO3   2. Hydrogen sulfide ion being oxidized into sulphur 2NaHS+O2(888)==2S+2NaOH Note: 888 is a kind of desulfurization catalyst   3. Desulfurization catalyst regenerate [888]R+O2=[888]OX+R   Our advantage 1. The equipment can run continuously in a long term for desulfurization. Using PH value to maintain the desulfurization efficiency, it has low operating costs. 2. The solution regenerates well and the sulfur does not accumulate to block tower. The regenerated sulfur particle is big, and the sulfur is easy to separate. At the same time, the desulfurization tower can be cleaned. 3. The solution is simple to mix and separate with strong chemical stability and easy to manage and operate.   Dry desulfurization  2. Dry type desulfurization   Product introduction The basic principle of dry type desulfurization is to use O2 react with H2S of the methane gas, and translate H2S into sulphur or sulphur oxides. The technological process is :Biogas→dehydration→desulfurization→ fire resistance→power generation or boiler combustion The dry type desulfurization system is suitable for the low content of hydrogen sulfide, small gas volume and high desulfurization, which best guarantees the extended lifespan of generator and the subsequent equipment.   Working principle 1. Fe2O3 · H2O + 3 H2S = Fe2S3 + 4 H2O (Desulfurization) 2. Fe2S3 + 3/2 O2 + 3 H2O = Fe2O3 · H2O + 2 H2O + 3 S(Regeneration)   Our Advantage 1. The structure is simple, and easy to use. 2. During the working process, it can be unattended with only regular material reloading, one with a preparation, and alternative operation. 3. Comparing with the wet desulfurization, it needs regular material reloading. 4. It is suitable for the treatment of gas with small volume, gas for high desulfurization rate. With the rapid detection of hydrogen sulfide test tube to determine the effect of inorganic sulfur removal, it can reach to 15ppm.   Our Services  Pre-sales services: 1.
