ABSTRACT:
A pipeline processing assembly for a pipeline adapted to convey a fluid from an upstream end of the pipeline to a downstream end of the pipeline. The assembly includes a pipeline pig for removing earthen matter and other debris from inside the pipeline. The pig is inserted into the pipeline at the upstream end, and has a dimension substantially equal to an inside diameter of the pipeline to form a seal between the pig and the pipeline. A vacuum source communicates with the pipeline downstream of the pig, and generates a reduced air pressure sufficient for moving the pig downstream through the pipeline. The pig gathers and moves the earthen matter and debris downstream through the pipeline and outwardly through an exit opening formed at the downstream end.
