FREMGANGSMAATE OG INNRETNING TIL BORTFOERING AV VED SVIKT FRA EN LAGERBEHOLDNING UTTREDENDE GASSER ELLER VAESKER SOM FORFLYKTIGER SEG VED UTTREDEN, SPESIELT TOKSISKE OG/ELLER VONDTLUKTENDE OG/ELLER AGGRESSIVE GASSER.

摘要

A method and apparatus for recovering the gases which are produced when a storage tank is operating abnormally, e.g., gases which are directly discharged through a safety valve during periods of overpressure, or else gases generated from liquids leakage outwardly therefrom, the escaping gases being cooled and liquified by heat exchange with a liquified low-boiling coolant gas, the liquified escaping gases then being passed to a collector which can have greatly reduced dimensions compared to conventional collectors.
