Surface Tensions of Carbonated 2‐Amino‐2‐methyl‐1‐propanol and Piperazine Aqueous Solutions

Abstract

Surface tensions of carbonated 2‐amino‐2‐methyl‐1‐propanol (AMP) and piperazine (PZ) aqueous solutions were measured by a surface tension meter which employs the Wilhemy plate principle. A thermodynamic model was proposed to correlate the surface tensions of both CO2‐unloaded and CO2‐loaded aqueous solutions by introducing the contribution of CO2 loading into the formulation of surface tension. Based on experiments and calculations, the effects of temperature, mass fractions of amines, and CO2 loading on surface tensions of carbonated aqueous solutions were demonstrated.

Experimental studies and artificial neural network modeling of surface tension of aqueous sodium l-prolinate solutions and piperazine blends

“…The surface tensions of aqueous solutions of SP and SP + PZ have been compared with various conventional solvents and aqueous amino acid salts for single concentration at constant temperature, as shown in Fig. 8 [2,4,18,19,38]. It is apparent from Fig.…”

“…In addition to this, surface tension of pure and aqueous solutions is crucial for the design and simulation of contacting equipment and processes such as gas absorption. This property influences the mass transfer and hydrodynamics of these systems, mainly multiphase systems, in which the interface between gas-liquid exists [2,4].…”

Application of Surface Tension Model for Prediction of Interfacial Speciation of CO2-Loaded Aqueous Solutions of Monoethanolamine

“…For instance, low surface tension solvents are desirable for packed columns while high surface tension solvents are preferred for membrane contactors in order to avoid unfavorable wetting phenomena . Surface tension measurements of CO 2 -loaded, − and -unloaded, ,,− alkanolamine solutions have been presented in the literature. Experimental data and model equations show that, despite the surface activity of most alkanoamines, their carbonated solutions present surface tension that increases with CO 2 loading. − …”
