The inhibitor has a low toxicity and manages a high degree of subcooling, up to 20°F. The effective dosage ranges from 550 ppm to 3000 ppm, depending upon the severity of the operating condition in each field. The performance of this inhibitor, the field conditions in which it was applied, and the benefits are discussed in this paper. These field cases helped establish the application technology for proper deployment of kinetic hydrate inhibitors. The success of these programs has confirmed the viability of using kinetic inhibitors as an effective hydrate control method. This kinetic inhibition technology not only provides an attractive cost-saving alternative to thermodynamic inhibitors; it also improves the safety of operation while lowering the environmental impact.
