Applicable scope: It's applicable to the purification and desulfurization of coal gas and town gas (desulfurization of H2S)
Characteristics: The purification degree of gas can be adjusted according to actual need and thus steady control of H2S content in gas can be realized.

1. Compared with dry desulfurization, this method needs lower running cost and avoids any increase of production costs caused by poor desulfurization performance and sulfur absorption in dry desulfurization.
2. Compared with other methods of wet desulfurization, this one is characterized by stable and sage operation with desulfurization efficiency more than 97%. The H2S content in gas can be reduced to below 50mg/Nm3.
