Abstract
The invention relates to a process for treating an aqueous solution from a subterranean formation of an oil and gas operation. The aqueous solution can be removed from the subterranean formation and treated in a heated centrifugal separator. The heated centrifugal separator can separate the kinetic hydrate inhibitor from the aqueous solution, and then the aqueous solution can be reintroduced into the subterranean formation.
