摘要： 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.
