摘要: Abstract Viscosities of aqueous solutions 4 amines aimed at CO2 capture by absorption were measured in the temperature range 20–80 ° C and for whole compositions. In addition, measurements loaded up to 1 mol CO2/mole amine three systems also performed. The data were, when possible, compared literature good agreement was found. Both unloaded modeled using NRTL-DVIS correlation. model able, both cases, accurately represent experimental except 17.9 wt.% MAPA system. average deviations, calculated as AARD between predicted values, all other cases within 5–6%.
