PROCESS AND INSTALLATION FOR EMPTYING TANKS HAVING CONTAINED THEREIN LIQUEFIED GAS ORIGINATING FROM MINERAL OIL AND/OR FROM THE CHEMICAL OR PETROCHEMICAL INDUSTRY, AND ITS APPLICATIONS

摘要

A tank contg. liquefied gas is emptied by evaporating a liquified inert gas in a heat exchanger, feeding the inert gas to the tank to displace the stored gas, passing the stored and inert gas in countercurrent through the heat exchanger, and collecting the liquified stored gas at its outlet. An installation for carrying out the process and its use for supercooling the liquefied gas are also claimed.
