若可能生成水合物,需注入水合物抑制剂。如醇类,甘醇、乙二醇、甲醇等。If hydrate formation is possible, hydrate inhibitors should be injected. Such as alcohol, glycol, glycol, methanol and so on.
输气管中生成水合物的真实情况The real situation of hydrate formation in gas pipeline:()A.气体在管内高速度流动,不可能在某一点生成水合物,而往往在数十米的管段上形成水合物。The gas flows in the tube at a high speed, so it is impossible to form hydrate at a certain point.#B.形成水合物会改变压降曲线形状。Hydrate formation changes the shape of the pressure drop curve.#C.生成水合物时伴随有热效应,要放出热量。熔解水合物时,要吸收热量。水合物的熔解热为335KJ/kg,对管线温降曲线有影响。The formation of hydrate is accompanied by a thermal effect, to release heat. When you melt hydrate, you absorb heat. The melting heat of hydrate is
