利用提浓锅炉烟道气C02饱充糖浆的探讨 温亦钦潘儿罗军 冯永茂 (广西来宾永鑫糖业有限公司 来宾546100) 摘要：锅炉烟道气经过除尘和降温后，经过汽水分离器去除游离水，用压缩机升压 至0．2MPa后，再进入吸附塔。变压吸附提纯烟道气中二氧化碳。利用吸附剂在 O．2MPa*gt．附操作压力下，选择吸附烟道气中的气态水、二氧化碳等气体，最终将二 氧化碳气体纯度富集在20％左右。二氧化碳经水环式真空泵榆送至制炼，对粗糖浆 进行饱充，取代糖浆硫漂，达到降低糖浆PH值、提高糖浆纯度、降低产品含硫量的 目的。 关键词 氧化碳；变压吸附；浓缩；饱充；糖浆 Concentrationofboilerflue andinfull of gasbyC02 charge Julce Wen Er，Luo Yi-qin，PanJun，FengYong-mao XinLaiBin 546100) (Yong GuangxiSugarIndustryCo．，Ltd．Laibin，Guangxi Abstract：Aftertheboilerflue dustremovaland removaloffreewater gas cooling，after separator，the boostto thenintothe tower．PSA offlue 0．2MPa．and carbondioxide． compressor absorption purificationgas usedin selected O．2MPa of Adsorbentthe selective water operatingpressure adsorption．theadsorptionvapor flue inthe dioxideandother the ofcarbondioxideconcentration gas，carbon gases，andultimatelypurity gas carbondioxide isabout20％．Thewatervacuum to full onthethick ring transportedsmelting，the pump charge insteadof sulfur reducethePHvalueofthe of syrup drift，to increased，the syrup syrup，syruppurity purpose thesulfurcontentof reducing products． dioxide：PSA：Concentration；Full Keywords：Carbon
