Abstract

During the rapid depressurization of a liquefied gas, its superheating can lead to a boiling liquid expanding vapor explosion (BLEVE). Such an event is of enormous concern during carbon capture and storage (CCS) given the significant amounts of pressurized CO₂ involved during its transportation and storage. This article presents, for the first time, the development and validation of a rigorous split-fluid blowdown model for predicting the degree of superheating following the rapid decompression of liquefied gases or two-phase mixtures with particular reference to CO₂. The model was successfully validated through a comparison of the predicted vapor- and liquid-phase pressures and temperatures against the recorded data from a number of depressurization tests conducted for pure dense-phase CO₂ and its mixtures representing those associated with different capture technologies. The effects of changes in the pressure-relief-valve diameter and CO₂ purity on the degree of superheating and, hence, the spontaneity of undergoing a BLEVE were investigated using the model.
