| 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. |
