天然气水合物抑制剂选用的探讨

Discussion on Selection of Natural Gas Hydrate Inhibitors

冬季,油田伴生气集输管线经常发生管线冻堵情况,加注甲醇防冻剂后能有效地防止管线冰堵的发生。甲醇作为水合物抑制剂具有很多的优点,但甲醇具有毒性且挥发性很强,随着世界各国及油田化工生产单位对环保及员工健康的关注,具有中等毒性的甲醇势必且应该被乙二醇代替。

In winter, the pipeline is often blocked by the pipeline, and the addition of methanol antifreeze can effectively prevent the occurrence of pipeline ice blocking.Methanol as a hydrate inhibitor has many advantages, but methanol is toxic and highly volatile, with the world＇ s oil and chemical production units in the oil and environmental health concerns, with moderate toxicity of methanol and should be ethylene glycol instead.
