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.

Abstract: An enhanced low noise relief valve renders the anodizing processing irrelevant to the low leakage nature of the valve member based on the tolerance between the tube portion of the valve member and the inlet bore of the machined housing. This is accomplished by providing an additional valve stem holder that acts as a stem holder through which at least part of the tube portion of the valve member extends, with the stem holder instead of the valve member tube being located adjacent to the bore of the machined housing. The stem holder does not need to be subject to the anodizing process, and therefore a tight tolerance between the valve member and stem holder provides adequate leakage control, and the anodizing process applied to the machined housing otherwise is separated from the location where leakage tolerance is critical.

Abstract: The invention relates to a system for controlling a flow of liquid from a first to a second reservoir (1,2). The system comprises an intermediate reservoir (4) having an inlet (5) in fluid communication with the first reservoir and an outlet (6) in fluid communication with the second reservoir. A valve (7) at the inlet moves between an open position in which liquid can flow from the first reservoir to the intermediate reservoir via the inlet and a closed position. The valve comprises a float (7a) that floats on liquid present in the intermediate reservoir and thereby controls the position of the valve dependent on the liquid level in the intermediate and second reservoirs. The closing is provided by the buoyant force of the float moving a closing surface (10) of the valve into a liquid tight engagement with the inlet thereby providing a liquid tight closure between the first and intermediate reservoirs.
