Abstract
A method of treating natural gas to remove contaminants is described. An input natural gas is mixed with water causing formation of COhydrates and CHhydrates. A natural gas having a reduced COconcentration, and a water-hydrate mixture comprising the COhydrates and CHhydrates, is output. The water-hydrate mixture is exposed to COgas forming a CO—CHgas mixture and a residual hydrate mixture. The CO—CHgas mixture is recycled to remove CH. The residual hydrate mixture is treated to produce HO which can be recycled for use in forming the water-hydrate mixture, and gaseous COfor use in use in stripping CHfrom the CHhydrates of the water-hydrate mixture.
