Abstract: The present invention is directed to the removal of mercury in a gas dehydration process using thermally table chemical additives. In the process a complexing agent is added to a recirculated glycol solvent as part of the glycol solution feed to the dehydration liquid contactor and recirculated continuously with the glycol solvent. The complexing agent selectively reacts with mercury in the wet natural gas to remove the mercury from the dry natural gas product.

Abstract: Processes for removing a sulfide or a degradation product thereof from in a gas dehydration system are disclosed along with corresponding gas dehydration systems. The processes and systems include contacting a stream comprising the sulfide or a degradation product thereof with an anionic resin to remove at least a portion of the sulfide or a degradation product thereof from the stream. The processes and systems can also be used in the removal of mercury from gas dehydration systems.
