Overview

The BS EN ISO 20088-3:2019 is a crucial standard for industries dealing with cryogenic materials. It provides a comprehensive methodology for determining the resistance of insulation materials to cryogenic spillage, specifically focusing on jet release scenarios. This standard is essential for ensuring safety and reliability in environments where cryogenic substances are handled, stored, or transported.

Importance of Cryogenic Spillage Resistance

Cryogenic materials, such as liquefied natural gas (LNG) and liquid nitrogen, are stored at extremely low temperatures. Any spillage can lead to rapid temperature changes, posing significant risks to both personnel and equipment. Insulation materials play a vital role in mitigating these risks by providing a barrier against the extreme cold. The BS EN ISO 20088-3:2019 standard helps in assessing the effectiveness of these materials in real-world scenarios, particularly in the event of a jet release.

Key Features of the Standard

• Comprehensive Testing Methodology: The standard outlines detailed procedures for testing insulation materials under cryogenic conditions, ensuring that they can withstand sudden and intense exposure to low temperatures.
• Focus on Jet Release: Unlike other types of spillage, jet release involves a high-pressure discharge of cryogenic material, which can be more challenging to contain. This standard specifically addresses this scenario, providing valuable insights into material performance.
• Safety and Compliance: Adhering to this standard helps organizations comply with safety regulations and industry best practices, reducing the risk of accidents and enhancing operational safety.

Applications

The BS EN ISO 20088-3:2019 standard is applicable across various industries, including:

• Oil and Gas: Ensuring the safe handling and storage of LNG and other cryogenic substances.
• Chemical Manufacturing: Protecting equipment and personnel in facilities that use cryogenic materials.
• Transportation: Enhancing the safety of vehicles and vessels that transport cryogenic goods.
• Research and Development: Supporting the development of new insulation materials and technologies.

Why Choose BS EN ISO 20088-3:2019?

Choosing the BS EN ISO 20088-3:2019 standard means prioritizing safety, efficiency, and innovation. By implementing the guidelines and testing methods outlined in this standard, organizations can ensure that their insulation materials are capable of withstanding the most demanding cryogenic conditions. This not only protects assets and personnel but also enhances the overall reliability and performance of operations involving cryogenic substances.

Conclusion

In an industry where safety and precision are paramount, the BS EN ISO 20088-3:2019 standard serves as an indispensable tool for assessing and improving the resistance of insulation materials to cryogenic spillage. Its focus on jet release scenarios provides a targeted approach to addressing one of the most challenging aspects of cryogenic material handling. By adhering to this standard, organizations can achieve greater safety, compliance, and operational excellence.

This document describes a method for determining the resistance of a cryogenic spill protection (CSP) system to a cryogenic jet as a result of a pressurized release which does not result in immersion conditions. It is applicable where CSP systems are installed on carbon steel and will be in contact with cryogenic fluids.

A cryogenic jet can be formed upon release from process equipment operating at pressure (e.g. some liquefaction processes utilize 40 to 60 bar operating pressure). Due to high pressure discharge, the cryogenic spillage protection can be compromised by the large momentum combined with extreme cryogenic temperature.

Although the test uses liquid nitrogen as the cryogenic liquid, the test described in this document is representative of a release of LNG, through a 20 mm orifice or less, at a release pressure of 6 barg or less, based upon simulated parameters 1 m from the release point. Confidence in this test being representative is based upon a comparison of the expected dynamic pressure of the simulated release in comparison with dynamic pressure from releases in accordance with this document.

It is not practical in this test to cover the whole range of cryogenic process conditions found in real plant conditions; in particular the test does not cover high pressure cryogenic jet releases that might be found in refrigeration circuits and in LNG streams immediately post-liquefaction.

Liquid nitrogen is used as the cryogenic medium due to the ability to safely handle the material at the pressures described in this document. The test condition is run at nominally 8 barg pressure.

ISO 20088‑1 covers cryogenic release scenarios which can lead to pooling conditions for steel work protected by cryogenic spill protection as a result of a jet release or low pressure release of LNG or liquid nitrogen. ISO 20088‑2 covers vapour phase exposure conditions as a result of a jet release or low pressure release of LNG or liquid nitrogen.
