Diethanolamine solutions viscosity

Abstract—Gas-liquid interfacial areas a and volumetric liquid-side mass-transfer coefficients kLa are experimentally determined in a high pressure trickle-bed reactor up to 3.2 MPa. Fast and slow absorption of carbon dioxide in aqueous and organic diethanolamine solutions are employed as model reactions for the evaluation of a and kLa at high pressure, and various liquid viscosities and packing characteristics. A simple model to estimate a and kLa for the low interaction regime in high pressure trickle-bed reactors is proposed. 

Viscosities of Aqueous Diethanolamine Solutions (weight % of amine)... 

As known in the industry and shown again in Figure 13, alcohol sulfates typically give the highest viscosity values when blended with a viscosity modifier such as the 1 1 cocodiethanolamide used here 1 1 refers to the mole ratio of diethanolamine to fatty acid used to prepare the alkanolamide. The Figure 13 curves end where the next addition of sodium chloride would cause the test solution to salt out. What is seen is the ability of SMEs to maintain a low viscosity...
