What are the main types of oil that flow through pipelines?
The main types of oil that flow through pipelines are crude oil, refined petroleum products, and natural gas liquids. Crude oil is the most common type of oil transported through pipelines, and it is typically classified into different grades based on its density and sulfur content. Refined petroleum products, such as gasoline, diesel fuel, and jet fuel, are also transported through pipelines, often in separate pipelines or batches to prevent contamination.
The type of oil transported through a pipeline depends on the pipeline’s design and purpose. Some pipelines are designed specifically for crude oil, while others are designed for refined products or natural gas liquids. The type of oil transported through a pipeline also affects the pipeline’s operating conditions, such as the pressure and temperature required to maintain flow.
What is the difference between light and heavy crude oil?
Light crude oil is a type of crude oil that is lighter in color and has a lower density than heavy crude oil. It is typically easier to refine and produces a higher yield of gasoline and other light petroleum products. Heavy crude oil, on the other hand, is thicker and more difficult to refine, producing a higher yield of heavier petroleum products such as diesel fuel and fuel oil.
The difference between light and heavy crude oil affects the way it is transported through pipelines. Light crude oil can be transported at a lower pressure and temperature than heavy crude oil, which requires more energy to pump through the pipeline.
