A method and an ester composition used therein for inhibiting, retarding, mitigating, reducing, controlling and/or delaying formation of hydrocarbon hydrates or agglomerates of hydrates. The method may be applied to prevent or reduce or mitigate plugging of conduits, pipes, transfer lines, valves, and other places or equipment where hydrocarbon hydrate solids may form under the conditions. At least one ester compound is added into the process stream, where the compound may be mixed with another compound selected from other amino alcohols, esters, quaternary ammonium, phosphonium or sulphonium salts, betaines, amine oxides, amides, simple amine salts, and combinations thereof.
一种用于抑制、延缓、减轻、减少、控制和/或延迟碳氢化合物水合物或水合物团聚体形成的方法及其所用的酯组合物。该方法可用于防止或减少或减轻导管、管道、输送线、阀门和其他在条件下可能形成碳氢化合物水合物固体的地方或设备的堵塞。将至少一种酯类化合物加入工艺流中,该化合物可与选自其他氨基醇、酯、季铵盐、鏻盐或锍盐、甜菜碱、胺氧化物、酰胺、单胺盐及其组合的另一种化合物混合。
