摘要： A temperature swing adsorption system includes a first adsorption bed configured to receive a feed stream and adsorb a contaminant from the feed stream to produce a product stream, a second adsorption bed configured to receive a portion of the product stream and a cooling stream to reduce a temperature of the second adsorption bed, a third adsorption bed configured to receive the heated product stream to increase a temperature of the third adsorption bed; a separation system to separate the cooled product stream into a first component stream and a second component stream, and a fourth adsorption bed configured to receive the first component stream and to enrich an adsorptive concentration of the first component stream. The enriched first component stream is directed to the second adsorption bed to provide the cooling stream.

摘要： Processes and apparatuses are provided for preparing liquified natural gas from a natural gas feed that comprises C5 to C7 hydrocarbons and C8 or greater hydrocarbons. An exemplary process includes providing for the preferential adsorption of the C8 or greater hydrocarbons from the natural gas feed over adsorption of hydrocarbons having less than 8 carbon atoms to provide a C8-depleted natural gas stream. The process continues with the preferential adsorption of the C5 to C7 hydrocarbons from the C8-depleted natural gas stream over adsorption of hydrocarbons having less than 5 carbon atoms to form a C5 to C8-depleted natural gas stream. The C5 to C7 hydrocarbons are preferentially adsorbed with higher selectivity and capacity than adsorption of the C5 to C7 hydrocarbons during preferentially adsorbing the C8 or greater hydrocarbons. The C5 to C8-depleted natural gas stream is then liquified.

摘要： 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.

摘要： 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-) to produce a purified natural gas stream wherein said second adsorption bed is regenerated by a temperature pressure swing adsorption process.

摘要： A process for reducing the size of sulfur removal units is presented. The process includes passing a regeneration gas from a regenerated contaminant adsorption unit through a fixed bed adsorber. The fixed bed adsorber adsorbs sulfur compounds above an equilibrium condition and releases adsorbed sulfur compounds below the equilibrium condition. The peak levels of sulfur in the regeneration gas are reduced and the processing of the regeneration gas reduces the size of sulfur removal units.

摘要： The invention involves a process for treating a natural gas stream comprising sending the natural gas stream first to an adsorbent unit for removal of mercury. Then the gas stream is sent to an absorbent unit containing a chemical solvent and a physical solvent for removal of carbon dioxide, hydrogen sulfide, carbonyl sulfide and organic sulfur compounds to produce a partially purified natural gas stream. This stream is dehydrated and becomes the product stream. The partially purified natural gas stream to a dehydration unit to remove water to produce a natural gas product stream. The impurities absorbed by the absorption unit are removed and a liquid stream is separated that contains the sulfur impurities. This liquid stream may be purified and stabilized before being shipped for further treatment.

摘要： Adsorption vessels and systems utilizing adsorption vessels are provided herein. In one embodiment, an adsorption vessel for receiving a fluid mixture and for separating a component from therein includes a vessel wall extending from a bottom end to a top end and defining a vessel chamber. A bottom inlet is formed in the bottom end of the adsorption vessel for introducing the fluid mixture to the vessel chamber. A filler material having a total porosity of less than about 25% and a density less than about 900 kg/m3 or an insert or both are positioned in the top void volume to increase overall performance of the adsorbent vessel.
