Abstract

The invention provides a desulfurization process of generator gas, comprising the following step: the generator gas containing sulfur is absorbed by a desulfurization solution containing a mimosa extract in a desulfurization tower; the process is characterized in that the desulfurization solution also comprises vanadium pentoxide; and the sulfur content of the generator gas is 1500-2500mg / Nm<3>. The process is suitable for a situation that the content of H2S in the gas is high. The method has high desulfurization rate and the sulfur content of the gas coming out of the tower is not more than 150mg / Nm<3>.

Description

technical field

[0001] The invention belongs to the technical field of gas purification, and in particular relates to a producer gas desulfurization process. Background technique

[0002] For coal gas desulfurization made from coal, the existing technology basically adopts wet desulfurization process. The process is basically divided into three categories: physical absorption method, chemical absorption method and oxidation regeneration method, among which the oxidation regeneration method is the most commonly used. The method is mature and reliable, among which the glue copying method, improved ADA method, ammonia liquid phase catalytic method and PDS method are the most widely used in China. Among them, the improved ADA method has the advantages of high desulfurization efficiency, fast absorption of hydrogen sulfide, mature technology, perfect process, high scale, and good technical and economic indicators; the main problem is that sulfur is easily precipitated during the...
