给气体或输气管上可能形成水合物的地段加热，使气体温度高于水合物形成的温度。该法在干线输气管上是不宜采用的，因为它会降低管道的输气能力。在矿场集气或城市配气站中，压降主要消耗在节流上，节流前后，温度下降很多，加热就成了这些地方防止水合物形成的主要方法。Heating a gas or gas pipe where a hydrate may form so that the gas temperature is higher than the temperature of hydrate formation. This method is not suitable for the main pipeline, because it will reduce the capacity of the pipeline. In gas collection or urban distribution stations, the pressure drop is mainly consumed in throttling. Before and after throttling, the temperature drops a lot, and heating becomes the only major method to prevent hydrate formation in these places.
