Have anyone stopped to think what the refinery uses to separate the product in the pipe line?............................. water, the refinery will send diesel fuel ,water , 85 octane gas ,water , 93 octane gas, water , the ethanol is added at the terminal ( our ethanol is brought in on rail cars) and the individual company's additives are also added at the time the truck is loaded
may have at one time, but now they use what they call "pigs" a mechanical seperator in the line that moves with the fuel.
they do NOT use water.
Pipeline pigs are devices that are inserted into and travel throughout the length of a pipeline driven by a product flow. They were originally developed to remove deposits which could obstruct or ****** flow through a pipeline. Today pigs are used during all phases in the life of a pipeline for many different reasons.
Although each pipeline has its own set of characteristics which affect how and why pigging is used, there are basically three reasons to pig a pipeline:
To batch or separate dissimilar products;
For displacement purposes;
For internal inspection.
