Solubility of Carbon Dioxide in Aqueous Solutions of Piperazine (PZ) at Elevated Pressures

Article Preview

Abstract:

The solubility of carbon dioxide (CO₂) was measured in (0.2, 0.4, 0.6 & 1.2) molars of aqueous solutions of Piperazine (PZ) at three temperatures (30, 40 and 60) °C. The measurements were made over the pressure range of 5 to 60 bar. The results are presented as a function of pressure. It has been found that PZ gives significantly higher CO₂ loadings at higher pressures. The influence of pressure on solubility is found to be positive. However, solubility decreases with the increase of temperature and PZ concentration.
