Simulation of LNG rollover in storage tanks
MetadataShow full item record
LNG rollover is the sudden mixing of stratified LNG layers, which can generate significant amounts of boil-off gas. Such event is a severe safety concern; however, there are no reliable models at industrial scales available in the literature. In this research, we extend the definition of the hydrostatic stability ratio for binary mixtures to multi-component mixtures. Moreover, the fundamental issues associated with LNG rollover are reviewed, and a new model for simulating rollover is presented.

Analysis of available data from liquefied natural gas rollover incidents to determine critical stability ratiosArjomandnia, P.; Tade, Moses; Pareek, Vishnu; May, E (2013)Liquefied natural gas (LNG) rollover refers to the sudden mixing of stratified LNG layers, which can cause the generation of significant amounts of boil-off gas. Such events are a significant safety concern in LNG storage ...
