During the production, storage and transportation of natural gas, the formation of hydrates will lead to severe accidents. Hydrate inhibitors are needed to avoid this occurrence in devices and pipelines. In light of this, a novel economical and eco-friendly kinetic inhibitor was developed. The optimal concentration for inhibiting was 1.5% for this new inhibitor. Under specific supercooling degree, the higher the system pressure, the worse the refrain effect. Under specific pressures, the higher the supercooling degree, the worse the refrain effect. A small amount of condensate oil affected the refrain performance; methanol increased the supercooling degree significantly. The rational filling process technique could effectively control inhibitor plugging resulted from the formation of hydrates.
