液相共存成分对氨法脱碳吸收液解吸co2的影响研究
, PP. 477-483
Keywords: 氨法,液相共存成分,解吸,co2
Abstract:
？考察了烟气中so2、nox和co2与氨水的反应机理,研究了模拟解吸液解吸过程中主要液相共存成分,如(nh4)2so3、(nh4)2so4、nh4no3、nacl、nh4cl和(nh4)2co3对co2解吸的影响.研究表明,不同液相共存成分、质量分数、ph值、表面张力等对co2解吸产生一定影响,大部分液相共存成分的存在,会降低脱碳溶液co2的解吸量.质量分数低于10％的液相共存组分对脱碳吸收液co2解吸过程的制约作用依次为(nh4)2so3>nh4no3>(nh4)2so4>nacl>(nh4)2co3.因此,在碳捕集前应对烟气中的杂质成分进行脱除,减少其对解吸液理化特性的影响.
