DN200. Full of diesel. That already amounts to approximately 15,700 liters of product inventory within the plant. While safety considerations typically focus on leaks, corrosion protection, and monitoring systems, it’s worth asking another question: How much product is actually in the system? Pigging technology can largely empty pipelines and reduce the product inventory. This means: higher product recovery fewer product losses lower release quantities during maintenance work reduced potential extent of damage In process engineering, this approach is often referred to as Hazardous Inventory Reduction: The less product there is in the system, the lower the amount that could potentially be released in the event of a malfunction. Sometimes, the safest amount of product is simply the amount that is no longer in the pipeline. How much product is stored in your longest process pipelines?
