LNG storage: safety analysis. Annual report for 1979
Progress is summarized on four projects in the area of LNG safety: (1) Rapid phase transformations in cryogens. An apparatus is described for experiments in which LNG will suddenly be subjected to a shock wave delivered from above. It is anticipated that cessation of boiling, followed by a very rapid delayed phase transformation, may occur. (2) Rollover phenomena. An apparatus is described for experiments which will examine the rates of heat and mass transfer across a density stabilized interface between two miscible strata. Preliminary data show that the apparatus is capable of producing data of the required accuracy. (3) Simultaneous boiling and spreading of cryogenic liquids. An apparatus is described for a study of the subject topic. Data obtained in this apparatus for the case of spreading without boiling are given and are shown to agree with available theories. (4) Modelling of LNG tank dynamics. A vessel containing saturated liquid nitrogen has been subjected to a variety of step changes in the imposed pressure in order to simulate experimentally the events which occur when an LNG tank is subjected to variations in atmospheric pressure. The results are compared with a mathematical model of tank behavior.
