Description

Technical Field

[0002] When producing synthesis gas, whether using coal, natural gas or heavy oil and residual oil as raw materials, the raw materials contain sulfides. During the production process, these sulfides will be converted into hydrogen sulfide and organic sulfur gas, which will cause catalyst poisoning, corrosion of metal pipelines and equipment, and cause great harm.

However, when the spraying liquid containing zinc oxide is sprayed with the synthesis gas through the spray pipe for desulfurization reaction, since the spraying liquid is sprayed from top to bottom and the synthesis gas is transported from bottom to top, part of the synthesis gas is not desulfurized in time and is transported into the filter cartridge by the air guide pipe, thereby reducing the purification effect.
