减压几乎是从海底天然气或气体凝液管中除去水化物堵塞唯一可选择的方法。这个方法通常应用于堵塞物的位置、大小或组成不清楚或不确切的情况下。通过减压使水化物分解成一个热和物质相互转化的过程，对于确定除去水化物堵塞的最佳方案来说，定量这种相互关系是很有必要的。本文提出了一种移动边界的数字模式来预测不同情况下水化物堵塞的分解速率。通过在一个内径为2in，长385in的管路径向相反的位置上安插16对红外线传感器和接受器，跟踪水化物堵塞物与气体界面移动，以测定水化物堵塞物的分解速率，实验证实了这个模式。
Decompression is almost the only alternative method of removing hydrate blockages from submarine gas or gas condensate tubes. This method is usually applied to the blockage of the location, size or composition is not clear or inaccurate circumstances. By decompressing the hydrate into a heat and converting the material into one another, it is necessary to quantify this correlation in order to determine the best solution to remove the clogging of the hydrate. In this paper, a numerical model of moving boundaries is proposed to predict the rate of hydrate blockage in different situations. Sixteen pairs of infrared sensors and receivers were placed on the opposite side of a pipe with an inner diameter of 2 inches and a length of 385 inches to track the movement of the hydrate blockage and the gas interface to determine the rate of decomposition of the hydrate blockage experimentally confirmed by this experiment mode.
