Hydrate inhibitor treatment can be used in a wide range of system applications including:
- Well bores during drilling
- Gas and oil transportation in subsea and onshore pipelines
- Across valves and chokes
Hydrates form when free water combines with low molecular weight hydrocarbons, namely Methane, Ethane, Propane, Butane, Pentane and Hexane. The gas composition affects the type and severity of hydrate formed (type I, II, or H). Other parameters affecting the hydrate potential include temperature, pressure and brine salinity.
Omni Industrial Solutions Low Dose Hydrate Inhibitors (LDHIs) can be categorised into two types – Kinetic Hydrate Inhibitors (KHIs) and Anti-Agglomerates (AAs). LDHIs have typical treatment rates of between 0.1 and 5.0% based on water production and are system specific. The advantages of using LDHIs over glycol/methanol include low capital expenditure, reduced supply costs, improved safety, improved environmental profile and no contamination of downstream processes.
