Abstract: Processes and apparatuses for recovering a high purity carbon dioxide stream. A first separation zone that may include a cryogenic fractionation column provides the high-purity CO2 stream. A vapor stream from the cryogenic fractionation column is passed to a second separation zone to separate the CO2 from the other components. The second separation zone may include a pressure swing adsorption unit or a solvent separation unit. The second separation zone provides a hydrogen enriched gas stream that may be used in a gas turbine. The second stream from the second separation zone includes carbon dioxide and, after a pressure increase in a compressor, may be recycled to the first separation zone.

Abstract: A method of pretreating a natural gas stream for a floating liquefied natural gas plant is described. A natural gas feed stream is introduced into an amine absorption unit and a temperature swing adsorption unit located on a ship. The temperature swing adsorption unit has a dehydration cycle and a CO2 removal cycle. The amount of motion of the ship, or the level of CO2 in the natural gas feed stream with reduced contaminants, or both, is monitored. If the amount of motion of the ship or the level of CO2 in the natural gas feed stream with reduced contaminants exceeds a predetermined value, temperature swing adsorption unit is switched from the dehydration cycle to the CO2 removal cycle.
