... and the effectiveness depends upon operating conditions and inhibitor product chemistry; which is supplied by the vendor and accuracy of this data is a key. However, if these chemicals are applied within extreme conditions, such as fluctuating high temperature and pressure then the properties of the inhibitor...

... thermal insulation and/or thermodynamic hydrate inhibitors (THIs) such as mono-ethylene-glycol (MEG) or methanol (MeOH). Subsea trees, manifolds and jumpers are particularly at risk because of the more rapid cool down time upon shut-in and the difficulty to insulate them efficiently. Typical jumper...

... multiphase transport. One of the most common mitigations is impeding hydrate formation in the free water phase by injection of a Thermodynamic Hydrate Inhibitor (THI). The most used inhibitors are Methanol, Mono-Ethylene Glycol (MEG) and Di-Ethylene Glycol (DEG). Typically, Methanol is used when regeneration...

... ABSTRACT Recent research has proved that kinetic hydrate inhibitors (KHI) are not only nucleation delayers but also growth inhibitors, therefore providing predictable, long-term hydrate protection over a range of operating conditions. This challenges the traditional perception that KHIs offer...
