催化裂化烟气排放控制技术现状及面临问题的探讨
|
摘要
催化裂化装置原料油当中往往包含噻吩、硫酚、环硫醚、硫醚以及硫醇等含硫化合物,因此在进行催化裂化反应的时候,一些含硫化合物就会在焦炭以及油浆当中存在。早在再生器中这些含硫焦炭就会由于氧化反应烟气,从而被直接的排放到空中,严重的污染了人们生活的环境,因此必须要采取有效措施,对其进行有效的控制。
Catalytic cracking unit feedstock oil often contained thiophene ring,thiophenol,sulfide,sulfide and mercaptan sulfur compounds,so when the catalytic cracking reaction,some sulfur compounds would exist in the coke and oil slurry.Early in the regenerator of the sulfur coke,due to the oxidation reaction of flue gas directly discharged into the air,the living environment of people was seriously polluted,so effective measures must be taken and the effective control be carried on.
