MAXIMUM OVERPRESSURE IN GASTIGHT CONTAINERS OF THE STORAGE AND TRANSPORT OF DANGEROUS LIQUIDS

For a design of containers suitable under safety aspects for the transport and storage of dangerous liquids, the maximum overpressure to be expected is an important value. The fundamentals for the determination of the internal pressure are pointed out for the simplified model of a rigid (i.e. not elastically or plastically deforming) and gastight container. Maximum overpressure values are calculated for about one hundred liquids of practical interest. The results show a significant influence of the compression of air in the ullage space caused by liquid expansion due to temperature rise (compression effect), particularly for liquids with high boiling points. The enlargement of the container volume due to a heating of the container shell plays no significant roll for all metal containers under the assumed conditions of storage and transport. The results obtained essentially bear out the stipulations for the test pressure and the filling limits laid down in the older German regulations for the transport of dangerous liquids in rail tank wagons and road tank vehicles without pressure relief valves. For the recently fixed and internationally harmonized regulations for tank containers the considerations and the results pointed out in this, require a review.
