  • Method and installation for treating a storage site
    Patent number: 4604115
    Abstract: The tank (1) is purged by gaseous nitrogen resulting from the vaporization of liquid nitrogen which has undergone an indirect heat exchange (2) with the gas issuing from the tank. This enables the purged products to be recovered. Application in the deballasting of ships transporting liquified petroleum gas or natural gas.
