Abstract: Sour syngas treatment apparatuses and processes for treating a sour syngas stream are provided herein. In an embodiment, a process for treating a sour syngas stream that includes sulfur components and carbon dioxide includes absorbing the sulfur components and carbon dioxide from the sour syngas stream in a primary liquid/vapor phase absorption stage with a solvent to produce a liquid absorbent stream. The liquid absorbent stream includes the solvent, the sulfur components, and carbon dioxide. A portion of the sulfur components from the liquid absorbent stream is directly oxidized in the presence of a direct oxidation catalyst to produce elemental sulfur and a recycle stream. The recycle stream includes an unconverted portion of the sulfur components and carbon dioxide. The recycle stream is recycled for further absorption of the unconverted portion of the sulfur components and carbon dioxide through liquid/vapor phase absorption.

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.

Abstract: Processes of producing cresols from a phenols containing feed are described. The processes involve a combination of dealkylation and transalkylation processes. The dealkylation process converts the heavy alkylphenols in an alkylphenols stream to phenol and olefins. The olefins produced in the dealkylation process are separated out. The methylphenols, which are not converted in the dealkylation process, and phenol react in the transalkylation process to generate cresols.

Abstract: A process for the removal of sulfur compounds from a feed stream. A first separation zone removes sulfur compounds and produces a partially cleaned stream. A first adsorption zone adsorbs the remaining organic sulfur compounds on a regenerable adsorbent a produces a treated gas stream. A portion of the treated gas stream may regenerate the adsorbent in the first adsorption zone by removing organic sulfur compounds. The organic sulfur compound rich stream can be passed to a non-regenerable adsorption zone. The non-regenerable adsorption zone will separate out the organic sulfur compounds and provide a re-treated gas stream which may be recycled to a portion of the process. The non-regenerable adsorption zone may include regenerable adsorbent, but the zone is not operated to regenerate the adsorbent while it is in the non-regenerable adsorption 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.
