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*- ions. A new type of
desulfurization bacteria was used in the biological desulfurization
process, and the desulfurization efficiency was higher than *9.5%
(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.
Working 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.
H2S is absorbed by biological scrubbing liquid in
washing tower, the main chemical reaction:
H2S+OH- = HS-+H2O;
H2S+CO3*- =
HS-+HCO-
Biological Regenation Reactor:
HS-*1/2O2 = S+OH- (with
catalysts of microorganisms)
Characteristics and
Advantages
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 of Various Desulfurization
Process
| Comparison | Wet Desulfurization | Dry Desulfurization | Biological Desulfurization |
| Construction Cost | low | low | high |
| Operating Cost | high | high | low |
| Efficiency | *9% | *5%**5% | *9.5% |
| Final Product | effluent / sulfur | solid waste | elemental sulfur |
| Secondary Pollution | positive, need to dispose effluent | positive, solid waste pollution | negative, elemental sulfur can be reused |
