Wet process+biochemical desulfurization

Wet flue gas & biochemical desulfurization technology is currently the most efficient way of desulfurization in China, improved on the basis of common wet flue gas desulfurization. It uses aqueous solution containing aerobic bacteria, phenolic substances, iron ions and alkaline substances to absorb organic and inorganic sulfur in biogas, avoiding precipitation of ferric hydroxide and large amount of precipitation of ferric sulfide usually produced by common desulphurization method. It has the advantages of strong stability in the alkaline solution, high efficiency in the desulphurization, less recycling amount of the solution, and low operation cost, reducing instability of the solution, decrease of the desulphurization efficiency, and plugging of the tower with precipitates, etc.
