Revue de l'aptitude à l'emploi de certains isolants pour le fond des réservoirs de GNL.

A review of the suitability of certain insulations for the bottom of LNG storage tanks.

Auteurs : PASTUHOV A., HANSBERRY J. W.

Résumé

Although LNG storage tanks have a history of reliability since 1958, there have been instances of unacceptable performance from the bottom insulation of certain facilities. Computations using finite element analysis show that rigid insulation of the cellular glass type will fail, when constrained, from high thermal stresses even under steady state conditions and very likely fail before steady state, from the higher temperature gradients experienced during cool-down. The same computation analyses performed on PVC foam results in stresses, under the same conditions of restrain and temperature difference, of 0.31 megapascals which is more than 50% lower than the tensile strength of 0.69 megapascals.
