More Information
Summary: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.
