TBAB和CP双添加剂水合物法分离烟气中的CO_2
An experimental study on CO_2 hydrate-based separation from flue gas with tetra-n-butyl ammonium bromide/cyclopentane solution
摘要
Abstract
Experiments for CO2 separation from flue gas（CO2/N2） are conducted with the one-stage hydrate method using TBAB（tetra-n-butyl ammonium bromide,C16H36NBr） and CP（cyclopentane,C5H10） as joint additives.The effects of TBAB and TBAB/CP on hydrate formation and separation efficiency were investigated and compared.The suitable conditions of 276.15 K and 2.0-3.3 MPa along with initial liquid gas volume ratio of 0.78 and the CP volume concentration of 0.6 % were obtained.Under such conditions,the gas uptake with TBAB/CP joint additives was 1.5-2.0 times higher than that in TBAB solution.Meanwhile,the CO2 concentration in residual gas phase could be decreased from 17% to 7%.The split fraction of 60%-70% was also higher than that of 40%-50% in pure TBAB solution.The result demonstrated that TBAB/CP system was evidently helpful for hydrate-based CO2 capture from the flue gast.关键词
