Abstract

Pressure reduction in a vessel with cryogenic liquid can result in emission of admixture vapor-liquid through the drainage pipeline and to the subsequent growth of pressure in a vessel. The task of non-stationary process of liquid swelling is put and solved for the description of this fact. The analytical decision of the task for transient of pressure reduction in a vessel with a cryogenic liquid is received. It allows to define the maximum rate of pressure reduction in a vessel depending on initial pressure and level of liquid in it, and also of degree of vessel filling. Examples for cases of storage of the liquefied natural gas in vessels with volumes 6 and 25 m3 are resulted.
