SYSTEM AND METHOD FOR INHIBITING CORROSION

摘要

Methods and systems are provided for forming clathrates to reduce or prevent corrosion in hydrocarbon facilities, such as pipelines, among others. An exemplary embodiment provides a method for isolating a corrosive gas in a hydrocarbon stream. The method includes combining a host compound with a hydrocarbon stream comprising a corrosive gas to form a clathrate, wherein a pressure or the reaction, a temperature of the reaction, or both, are controlled to maximize formation of a clathrate of the corrosive gas and minimize the formation of a clathrate of a hydrocarbon in the hydrocarbon stream. The clathrate is separated from the hydrocarbon stream and melted to remove the corrosive gas.
