Product Description

Detailed Infomation:

The major contaminant in biogas is H₂S which is both poisonous and corrosive, and causes significant damage to piping, equipment and instrumentation. Biological desulfurization (BDS) is a process in which sulfur compounds (H₂S, organic sulfur) are catalyzed by microorganisms or their enzymes, and the sulfur-containing organic compounds are converted into elementary sulfur and a trace amount of SO₄^2- ions. A new type of desulfurization bacteria was used in the biological desulfurization process, and the desulfurization efficiency was higher than 99.5% (higher than the traditional desulfurization process ).

Biological desulphurization of biogas can be performed by using micro-organisms. Most of the sulphide oxidising micro-organisms belong to the family of Thiobacillus.

Management System Certification: ISO9001:2008, ISO14001:2004, OHSAS18001:2007

Principle:
Biological desulfurization process can be divided into three units: (1) scrubbing tower  (2) bio-regeneration reactor  (3) sulfur separator.

As shown in the following flowchart, the alkaline bio-washing liquid is ejected from the top of the scrubber and contacted with the sulfur compounds (mainly H₂S) gas entering from the bottom of the scrubber. During this process, the H₂S will be efficiently absorbed. Then the rich liquid containing sulfide flows into the bio-regeneration reactor from the bottom of the scrubber, and the alkaline biological detergent will be regenerated by the biological treatment of the desulfurization microorganism. The elemental sulfur will be seperated from sulfur separator in form of particle precipitation.

Chemical Reactions:
H₂S is absorbed by biological scrubbing liquid in washing tower, the main chemical reaction:
H₂S+OH^- = HS^-+H₂O; H₂S+CO₃^2- = HS^-+HCO₃^- 
Biological Regenation Reactor: 
HS^-+1/2O₂ = S+OH^-  (with catalysts of microorganisms)


Characteristics of Wet Desulfurization :
1. No need of catalyst and oxidizing agent (except air).
2. No need to deal with chemical sludge.
3. It has little biological pollution, low energy consumption, high sulfur recovery, high efficiency and no odor.

Comparison: (Dry Desulfurization,Wet Desulfurization & Biological Desulfurization)
 

Type	Initial Investment	Efficiency	Operating Cost	Management and Maintenance	Final Product	Application
Dry Desulfurization	Lower	85%-95%	Replacement cost of desulfurizer, medium	Frequent replacement of desulfurizer and potential corrosion of tower	solid waste	Fine desulphurization is suitable for small gas flow and low concentration of hydrogen sulfide.
Wet Desulfurization	Medium	99%	Consumption of drugs is high.	Automatic control, Manual labor is needed to add the drugs	effluent  sulfur	It is suitable for intake gas with large methane flow and high hydrogen sulfide concentration. Intake concentration above 20000ppm
Biological Desulfurization	Medium	99.5%	Cheapest, less than 2 cents for each biogas treatment.	Fully automated operation, simple maintenance.	effluent  sulfur	Most suitable for medium-scale biogas desulfurization (200-2000 Nm³/h, initial concentration of hydrogen sulfide in 2000 - 10000 ppm)
