REGENERATION OF KINETIC HYDRATE INHIBITOR

摘要

The present invention relates to a method and system for regeneration of kinetic hydrate inhibitor when it is used without a thermodynamic inhibitor. In that the use of a distillation column or tower is not needed, the present invention enables a more compact system, which also improves the possibility for heat integration of the regeneration process leading to very low energy consumption. Additional improvements over the prior art include reduced cost of buying new chemicals, reduced environmental impact because the chemicals are not discharged with the produced water and the possibility for the use of higher concentrations of kinetic hydrate inhibitor with still reduced cost and environmental impact.
