Experimental determination of carbon dioxide and nitrous oxide co-solubility in liquid oxygen

Knowledge of solid solubility in condensed gases is of great practical interest, e.g. in designing the cryogenic processes involving separation of gas mixtures into their components. attention has been paid to developing and implementing an operational procedure in order to reduce the probability of accidents in low temperature industry. terest in the solubility data is closely connected to the problem of accumulation of impurities in process plant and storage tanks. Such accumulations in liquid oxygen may cause fouling and blockage in heat exchangers and pipelines and it may eventually cause serious explosions, for instance that occurred in Bintulu, Malaysia, in 1997 [J. Loss Prevent. Process Ind. 14 (2001) 167]. lity data for pure compounds in liquid solvents are available for various systems, but co-solubility data are drastically lacking. As an attempt to begin filling this gap, the CO2–N2O co-solubility has been measured in liquid oxygen at 90.44 K. For this purpose a new device named “atomiser–injector”, was designed, constructed and tested in our laboratory.
