Since the coal gas contains a large amount of harmful gas, it cannot be directly discharged into the air, so the coal gas needs to be processed. During the processing of the coal gas, a bubbling saturator and a spray saturator are usually used. The bubbling saturator needs to be regularly filled with a large amount of acid and water, which destroys the conditions for crystallization. In addition, the crystallization stays at the bottom of the saturator for a short time, resulting in small crystalline particles that cannot meet the normal demand. The spray saturator is made of stainless steel and has a long service life. It integrates acid washing absorption, crystallization, acid removal, and evaporation. It has the advantages of small coal gas system resistance and large crystalline particles.
