    Abstract: A coherent body (B) of wet crushed ice is pumped along a pipe (5). The crushed ice body can be used as a means of cleaning the pipe wall, as a means of driving a product liquid out of the pipe for recovery, or as a barrier for preventing mixing of two different bodies of liquid (1,2) in the pipe to either side of it. Being coherent but flowable and non-tensile, the mass of crushed ice can negotiate internal constrictions, obstructions and junctions of the pipe readily, unlike conventional solid or gelled pigs.

    Abstract: In a system for loading a liquid into a tank truck by means of a pipeline, a pig is used for pushing product through the line toward the truck. This pig is stored at the source end of the line and is caused to move through the line first toward the truck end, and then back to its storage location at the source end, all in response to the operation of a ''''pig start'''' pushbutton.

    Abstract: Carbon dioxide is injected into a surface pipeline to maintain a pressure near that required to form a two two-liquid phase hydrocarbon-carbon dioxide system. The two-liquid phase region is placed as a slug between two hydrocarbons to be transported within the pipeline. The two-liquid phase slug prevents the mixing of the hydrocarbons being pipelined. The slug material exhibits a lower viscosity than the flowing hydrocarbons so that it flows in the turbulent regime causing a cleansing action in the pipeline and also reducing the extend of its own tailing. Upon effluence from the pipeline the carbon dioxide may be vented to the atmosphere to separate it from the hydrocarbons.

    Abstract translation: 将二氧化碳注入表面管道以保持形成两个双液相烃 - 二氧化碳系统所需的压力。 双液相区被放置在两条烃之间，在管道内运输。 双液相段阻止被流动的烃的混合。 块状材料的粘度比流动的碳氢化合物低，因此它在紊流状态下流动，导致管道中的清洁作用，并且还减少了其自身拖尾的延伸。 在从管道流出时，二氧化碳可以排放到大气中以将其与烃分离。
