Abstract: The present disclosure generally relates to a system and method for the simultaneous transport of Crude Oil and Naphtha in a cross-country crude oil pipeline. The system includes the batch/zone of crude blend followed by lighter crude to clean and dissolve the asphaltene content of the crude blend. The naphtha batch/zone is sent securely in between the batch/zone of water. To carry out the cleaning of inner surface of the pipe various types of pigs have been used, the pigs have been designed to scrap the inner surface of the pipe and collect the foreign particle as well. The light crude oil is used to dissolve the asphaltene and resin components of crude blend, pigs are used to clean the surface and as well as a separating barrier in between the two layers.
