| Summary: | Ionic Liquids (ILs) have attracted widespread attention as an alternative class of
solvent for C02 capturing from different streams. Among the ILs, ammonium based
appear as a promising class for C02 absorption due to water miscibility, water
stability, comparatively low viscosity, low density and large free volume. For design
of new acid gas removal equipments, thermophysical data is essential and before
using the ILs for C02 separation it is essential to have knowledge of solubilityof C02
in ILs. In present work the Physical properties (density, viscosity and refractive index)
of aqueous solutions of tetrabutylammonium hydroxide (TBAOH), aqueous solution
of Piperazine (PZ) and aqueous blend of TBAOH and PZ have been measured in the
temperature range of 303.15 to 333.15 K. The C02 solubility in aqueous solutions of
TBAOH, aqueous solution of PZ and aqueous blends of TBAOH and PZ was
determined by using high pressure solubility cell at temperatures (303.15, 313.15 and
333.15 K) and pressure range from 2 to 10.37 bar. From the measurements it was
found that an aqueous solution of TBAOH with higher concentration has lower
density than all other solutions. |
