In the highly specialized field of cryogenic gas processing, the functionality and efficiency of Air Separation Units (ASUs) are crucial. These units, tasked with the critical role of segregating atmospheric air into its elemental gases—including oxygen, nitrogen, and argon—require precise and reliable components to ensure optimal operation. Among these, the oxygen pressure control valve is integral, serving a pivotal role in maintaining the delicate balance needed for the safe and efficient management of gases at sub-zero temperatures.
Enter Air Liquide, a frontrunner in the global gases industry, renowned for its innovative approach to providing gases, technologies, and services across the industrial and health sectors. With a footprint spanning more than 75 countries, Air Liquide leverages its vast expertise to tackle environmental and energy challenges, thereby boosting performance across a wide array of applications.
Air Liquide encountered a formidable challenge in regulating the pressure of gaseous oxygen (GOX) and liquid oxygen (LOX) at the extreme temperature of -321°F across different locations. This difficulty arises because, at such low temperatures, oxygen behaves unpredictably, with slight pressure changes potentially leading to rapid phase changes or volume expansions. This complicates the task of maintaining stable and controlled conditions.
Air Liquide's operational demands were centred on achieving exact flow control and secure tight shutoff mechanisms, essential for ensuring operational safety and enhancing efficiency. These requirements are particularly crucial in the context of cryogenic gases, where precise flow management and the ability to completely halt gas movement are vital to prevent leaks and ensure safe handling of potentially combustible materials.
Additionally, noise reduction posed a significant challenge. This is due to its potential to cause disruptions in environments where maintaining a quiet atmosphere is crucial, such as in close proximity to residential areas or in laboratories where sensitive experiments are conducted.
The sensitive and specialized nature of cryogenics means the majority of off-the-shelf control valves were not fit for these dual purposes. To ensure safety and efficiency, Air Liquide approached Trimteck for a custom-engineered solution.
After a detailed consultation process, Trimteck proposed a design for a custom speciality control valve. The Cryogenic OpGL Control Valve, ranging in sizes from 1” to 6” CL300, was specifically designed to meet the rigorous demands of Air Liquide’s cryogenic applications. The valves featured:
