Abstract: A pressure swing adsorption process is provided to remove oxygen from a hydrogen stream through the use of a copper material in combination with layers of adsorbent to remove water, C2 and C3 hydrocarbons, as well as other impurities. The feed gas comprises more than 70 mol % hydrogen, at least 1 mol % methane and more than 10 ppmv oxygen. The purified product hydrogen stream comprises greater than 99 mol % hydrogen, with less than 1 ppmv oxygen.

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.

Abstract: Methods and apparatuses for removing impurities from a hydrocarbon stream are provided herein. In an embodiment, a method for removing impurities from a hydrocarbon stream includes providing the hydrocarbon stream that includes carbon dioxide in an amount of greater than about 50 ppm by mole. Carbon dioxide is selectively adsorbed from the hydrocarbon stream to produce a treated hydrocarbon stream that has less than or equal to 50 ppm by mole of carbon dioxide. The adsorbed carbon dioxide is desorbed to produce a raffinate stream that includes the carbon dioxide. The carbon dioxide is separated from the raffinate stream using a solvent separation technique to produce a treated raffinate stream.
