| Résumé : |
The mixing of propane, or propane-rich liquids, with n-butane, or n-butane-rich liquids, under 1 atm. pressure in fully refrigerated vessels is widely practised in the liquefied petroleum gas (L.P.G.) industry.
A common experience during these mixing operations is that the volume of vapour generated depends on whether the propane is added to the n-butane or vice versa. In general, about twice as much vapour is generated when a propane/n-butane mixture is produced by adding propane to n-butane compared with adding n-butane to propane. This work describes: A/ A rig developed for the mixing of two boiling liquid gases at 1 Atm. B/ Some experimental mixing results carried out on a laboratory scale which demonstrate that the phenomenon is not an artefact. The results obtained showed that: 1. The vapour contains some n-butane. 2. When propane is added to n-butane, with surface and bottom delivery, the boil-off is affected by the delivery rate. 3. When adding propane to n-butane, the volume of vapour evolved is between 1.5 and 2.0 times the volume produced by adding n-butane to propane to produce the same mixture. 4. The volumes of vapour generated are larger when the pure components are mixed. C/ A path-dependent mixing model is developed which predicts the vapour volume generated within the experimental error. The model decouples the vapour generation and liquid mixing processes, and indicates how C₃/n-c₄ mixing generates much larger volumes of vapour than a n-C₄/C₃ mixing operation. |
