Abstract
Methods and systems for managing hydrate formation in a hydrocarbon stream. The methods and systems include injecting into the hydrocarbon stream a thermodynamic hydrate inhibitor and a kinetic hydrate inhibitor. Addition of the kinetic hydrate inhibitor allows for reduction in the amount of thermodynamic hydrator inhibitor needed. The kinetic hydrate inhibitor has high temperature stability to allow for recycling and reuse.
