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.
