Determination of the resistance to cryogenic spill of insulation materials - Part 2: Vapour exposure (ISO 20088-2:2020)

This document describes a method for determining the resistance of Cryogenic Spill Protection (CSP) systems to vapour generated from a cryogenic liquid release where the liquid content is practically zero. It is applicable where CSP systems are installed on carbon steel.
The test provided in this document is not applicable to high pressure cryogenic liquid releases that can be found in refrigeration circuits and in LNG streams immediately post-liquefaction.

Bestimmung der Beständigkeit von Isoliermaterialien bei kryogenem Auslaufen - Teil 2: Dampfbelastung (ISO 20088-2:2020)

Dieses Dokument beschreibt ein Verfahren zur Bestimmung des Widerstands von CSP-Systemen (Schutz gegen kryogenen Auslauf, en: cryogenic spill protection) gegen Dampf, der aus einer Freisetzung einer kryogenen Flüssigkeit entsteht, wobei der Flüssigkeitsgehalt praktisch null ist. Es ist anwendbar, wenn CSP-Systeme auf Kohlenstoffstahl installiert sind.
Die Freisetzung von Flüssigkeitsstrahlen kann durch Freisetzung von verflüssigtem Erdgas (LNG, en: Liquified Natural Gas) aus Prozessanlagen, die unter Druck stehen, entstehen, z. B. nutzen einige Verflüssigungsprozesse einen Betriebsdruck von 40 – 60 bar. Jedoch wird in bestimmten Abständen vom Freisetzungspunkt erwartet, dass der Flüssigkeitsanteil so abnimmt, dass eine Flüssigkeitskühlung im Strom praktisch keine Auswirkung hat.
Es sollte beachtet werden, dass es bei dieser Prüfung nicht praktikabel ist, den gesamten Bereich der unter realen Anlagenbedingungen auftretenden kryogenen Prozessbedingungen abzudecken; insbesondere deckt die Prüfung keine Freisetzungen von kryogenen Hochdruckflüssigkeiten ab, die in Kühlkreisläufen und in LNG-Strömen unmittelbar nach der Verflüssigung vorzufinden sind.
Als kryogenes Medium wird flüssiger Stickstoff (LN2) genutzt, da das Material bei den in dieser Norm beschriebenen Drücken sicher gehandhabt werden kann.
ISO 20088-1 deckt die Freisetzung von kryogenen Flüssigkeiten ab, die bei durch CSP geschützten Stahlarbeiten zu einer Flüssigkeitsansammlung führen können. ISO 20088-3 deckt strahlförmige Freisetzungsbedingungen ab, unter denen im Strom Flüssigkeit vorherrschend ist.

Détermination de la résistance des matériaux d'isolation thermique suite à un refroidissement cryogénique - Partie 2: Phase vapeur (ISO 20088-2:2020)

Le présent document décrit une méthode pour déterminer la résistance de systèmes de protection contre la fuite cryogénique (CSP) à la vapeur générée par une émission de liquide cryogénique dont la teneur en liquide est quasi-nulle. Cette méthode s'applique quand des systèmes CSP sont installés sur de l'acier au carbone.
L'essai fourni dans ce document ne couvre pas les émissions de liquide cryogénique sous haute pression que l'on peut trouver dans les circuits de réfrigération et dans les courants de GNL immédiatement après la liquéfaction.
