摘　　要：某公司32万吨/年硫磺回收装置利用钠碱法脱硫技术结合液硫池脱气废气改造以及提高氢气质量等措施,使装置烟气SO2排放从均值从370mg/Nm3降至30mg/Nm3以下。达到了烟气SO2排放低于50mg/Nm3的新标准。同时,烟气排放中的非甲烷总烃及苯含量也达到排放要求。A company’s sulfur recovery unit of 320,000 tons/year utilized the modif ication of degassing exhaust gas of the sulfur tank of the SO2 solution by the sodium-alkali desulfurization technology and the improvement of hydrogen quality to reduce the emission of flue gas SO2 from an average of 370mg/Nm3 to less than 30mg/Nm3.A new emission standard of less than 50mg/Nm3 has been achieved.At the same time,the total non-methane hydrocarbon and benzene content in the flue gas emission also meet the emission requirement.
