Petroleum product pipelines are an efficient method of delivering product to distribution terminals. These pipelines are multi-purpose, in that they deliver many different products through one or two pipes. Usually fuel products are injected into the pipe sequentially, with no barrier between products.
What Happens When Transitioning?
When transitioning from one fuel to another (i.e. diesel to gasoline, high to low octane) a mixture phase is present, where two products are blended over a period of time. Terminal operators must switch between Product A, Slop, and Product B tankage precisely, otherwise product quality can suffer, and/or too much product must be re-processed. Mistakes can be costly and time consuming.
Today, NIR spectroscopy (either full spectrum DG-NIR or discrete wavelength photometers) can be used to detect both quantitative and qualitative pipeline interface transitions. This is achieved by comparing the current sample in the pipe with a library of materials in the analyser’s database. The data provides significant information about the product and classifies it as one of various grades of gasoline, diesel, fuel oil, etc. to allow automatic valve switching, so that more fuel can be used and sold, without waste.
