Abstract
The invention discloses a composite piperazine organic amine desulfurizing agent. The desulfurizing agent is prepared by uniformly mixing a main absorbent, a secondary absorbent, an auxiliary absorbent and additives, wherein the main absorbent is dihydroxyalkyl piperazine organic amine, the secondary absorbent comprises alkylol amine, aliphatic amine, alicyclic amine and aromatic amine type organic amine, the auxiliary absorbent is polyether glycol, and the additives comprise acids, water and a defoaming agent. A solidifying point of the composite amine is lower than that of single organic amine, so that system blockage caused by organic amine crystallization in a utilization process is reduced; the secondary absorbent and the main absorbent form absorption-desorption complementation; the auxiliary absorbent has a function of organic combination of a chemical absorption process and a physical absorption process to improve absorption-desorption comprehensive performances. According to different chemical components, contents and volumes of to-be-treated flue gas (tail gas), specific substances and consumption quantity of the main absorbent, the secondary absorbent and the auxiliary absorbent can be regulated to obtain favorable composite desulfurization effects.
