One of the most important aspects of cylinder and tank compression of gasses is to achieve gas stability within the container so that the composition will remain within the defined, acceptable limits for that particular gas. This stability needs to be achieved in order to ensure safe delivery of the gas during usage for a designated period of time, and also during longer periods of time such as prolonged storage. Keeping gases stable is a huge undertaking and it is a very important one as people’s lives literally could be in danger otherwise. Thanks to improvements in cylinder technology we here at US Gas can help ensure you get only the safest and most efficient cylinders for all of your gas needs.
Keeping Gases Stable
Meeting the goal of stability during storage and shipment isn’t always easy. This is because there are many factors which will impact the stability of gases within cylinders and there are many elements that must come together to achieve safe stability of the various types of gases. Some of these factors include : ensuring the gas itself doesn’t break down too quickly in the container, that outside environmental factors such as temperature does not affect the gases inside the cylinder, and that normal wear and tear and jostling of the containers during shipping and storing does not affect the gas in a negative way.
When it comes to keeping gases stable and safe there are many great improvements in cylinder technology that help ensure the short term and long-term stability and safety of gases. Short-term is easy to take care of because not much can happen in the course of a few weeks or months; it is the long-term care that is an issue at times. “The long-term stability of reactive gases can be problematic due to the concentration of the gas molecules as well as the molecules inside the cylinder. This can occur through chemical reaction, adsorption, and phase change. It’s even more challenging to prevent reactions within small-volume cylinders due to the greater ratio of internal surface area to internal volume” (CPV). These issues combined with the fact that there are more and more gasses and gas combinations being used in a range of industries today makes it even more complex of an undertaking. But this is why trusting an expert like US Gas is the best way to ensure you are getting the best service and the highest quality of cylinders made and maintained with the highest quality of materials and the newest technologies.
Aluminum Cylinders vs. Steel Cylinders
Steel is the traditional material used in gas storage cylinders and are typically the most popular choice among industry experts. However, aluminum cylinders have been gaining popularity when it comes to portable containers and cylinders since it is such a light weight material that still offers a great deal of strength and durability. It has also been noted that the gas stability among a wide variety of reactive gases is better in aluminum containers than in steel. This is good news as more industries begin to use various gases and some industries such as the medical field develops new combinations and concentrations of gases to use with patients. Aluminum containers are showing potential of being the go-to cylinders for these sorts of gas storage and usage needs because they are perfect for keeping gases stable and are a prime example of the improvements in cylinder technology has brought to us in recent years.
Enhancing Stability with Cylinder Technology
To improve specialty gas stability, US Gas uses a number of techniques that minimize active sites or reduce the frequency of catalytic surfaces in the cylinders. Some of the most common techniques used to achieve this include:
- Inspecting cylinders with a thorough visual examination to check for obvious wear and tear and damage to the cylinder and its various components.
- Vacuum checks will also need to be performed on a regular basis in order to ensure that the cylinder stays free of moisture and condensation inside the cylinder or tank.
- Washing the interior of the cylinder using a mild detergent and rising it well with de-ionized water and then drying it fully.
- Polishing the interior of the cylinder with a special mechanical or chemical process can replace washing and also helps remove the need to worry about drying the container afterwards.
- To dry the cylinder completely after cleaning it needs to be placed in a specially designed oven for eight hours at temperatures between 100°F and 150°F to bake out he moisture.
These tips and pointers can help businesses that utilize gas cylinders and tanks to be successful in achieving gas stability within your cylinders. One of the biggest concerns for businesses using gases in their daily operations is keeping gases stable and safe during usage and storage. Thanks to the many improvements in cylinder technology this can easily be achieved. To learn more, contact US Gas today and let us show you how we can take care of your gas storage and care needs!
