Chlorine cylinders are typically filled to what percentage?

Chlorine cylinders are typically filled to about 85% capacity. This percentage ensures that there is enough space in the cylinder for the chlorine gas to expand and contract as temperatures fluctuate. Filling the cylinder to this level provides a margin for pressure changes that occur with temperature variations, which is crucial for safe handling and storage. An 85% fill also accommodates the liquid chlorine's properties, allowing for proper distribution and use without the risk of excess pressure buildup within the cylinder. Understanding this standard fill level is important for the safe operation of chlorine gas in water treatment facilities.
