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 COstream. A vapor stream from the cryogenic fractionation column is passed to a second separation zone to separate the COfrom 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.

Apparatuses and processes for the recovery of carbon dioxide streams

A process of treating a natural gas stream is provided comprising sending natural gas stream through a first adsorbent bed to remove water and heavy hydrocarbons (C8+) to produce a partially treated gas stream in which the first adsorbent bed is regenerated by a temperature swing adsorption process and then sending the partially treated gas stream through a second adsorption bed to remove carbon dioxide and lighter hydrocarbons (C7&#x2212;) to produce a purified natural gas stream wherein said second adsorption bed is regenerated by a temperature pressure swing adsorption process.

Adsorption process for treating natural gas

Process for retrofitting existing processing units for natural gas fee streams. A portion of the dehydration adsorbent is removed from the vessels of the dehydration unit and is replaced with an adsorbent for heavy hydrocarbons. In operation the vessels are operated in thermal swing adsorption processes with reduced cycle times compared to the original design.

Processes for removing heavy hydrocarbons and water from a stream of natural gas

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.

Apparatuses and methods for removing impurities from a hydrocarbon stream

An exemplary embodiment can be a process for removing one or more sulfur compounds in a gas hydrocarbon stream. The process may include feeding the gas hydrocarbon stream to a prewash zone containing an alkali stream and passing the gas hydrocarbon stream from the prewash zone to an extraction zone. Usually, the gas hydrocarbon stream includes one or more sulfur compounds and the prewash zone includes a hollow fiber membrane.

Process for removing one or more sulfur compounds and an apparatus relating thereto

A system and process for the removal of carbon dioxide (CO) from a feed natural gas having variable flow rates and inlet COlevels.
