Abstract
Systems and methods of this disclosure make use of positive pressure to evacuate pipeline product contained within an isolated section of pipeline. In embodiments, an inert fluid is injected at a first location along the isolated section at a pressure above that of a non-isolated section of pipeline The displaced pipeline product, which may be filtered, then flows out of the isolated section at second location along the isolated section and into the non-isolated section. In other embodiments, a pressure differential between the isolated and non-isolated sections is created by lowering a pressure of the non-isolated section below that of the isolated section. The pipeline product may be a liquid, a gas, or a mixture of the two. The composition of product may be monitored as it flows through the isolated section or as it exits the section. Evacuation may be slowed or stopped based upon the composition.
