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. © (2014) Trans Tech Publications, Switzerland. publisher: Trans Tech Publications Ltd date: 2014 type: Article type: PeerReviewed identifier: Murshid, G. and Shariff, A.M. and Keong, L.K. and Azmi Busam, M.
