Investigation on performances of non-loss storage for cryogenic liquefied gas Original Research Article

In this paper, effects of liquid volume fraction, temperature and work pressure in cryogenic vessels on the pressure rise rates in cryogenic vessels are analyzed. Graphs of the relation between storage-pressure and heat flow received by the container per unit of volume for various volume fractions are proposed, and also graphs of the relation between time and pressure of non-loss storage for various volume fractions are presented. The best volume fraction is defined. Also, the graphs of the relation between environmental temperature and the performance of non-loss storage are proposed. In addition, the phenomenon of liquid-temperature layering is analyzed and methods to reduce this layering are suggested. These results have significance in the design, usage and selection of cryogenic vessels.
