摘要:
In a process for ammonia production, in which an additional separation step within the ammonia loop is used, remaining ammonia in the recycle feed gas is extracted by condensation in the additional separation step and adsorbed over a swing adsorption bed placed after the separator. This way, the inlet concentration of ammonia to the converter is reduced. The swing adsorption bed can have pressure swing adsorption configuration, temperature swing adsorption configuration or purge swing adsorption configuration.

A process is disclosed for the removal of low molecular weight sulfur containing compounds from a gas feedstream, preferably a natural gas feedstream. The process provides for passing a gas feedstream comprising low molecular weight sulfur containing compounds though a regenerable adsorbent media which adsorbs low molecular weight sulfur containing compounds to provide a low molecular weight sulfur containing compounds-lean gas product and a low molecular weight sulfur containing compounds-rich adsorbent media. The regenerable adsorbent media of the present invention is a cross- linked macroporous polymeric adsorbent media.

摘要:
The present disclosure relates to processing organic compounds, such as manure or other organic waste, comprising a first containment or mixing chamber, a first anaerobic chamber, and a second anaerobic chamber. A first anaerobic chamber may receive organic compounds from a first containment or mixing chamber, and may provide a fluid stream to a second anaerobic chamber. The second anaerobic chamber may comprise a substrate, such as lava rock, with bacteria growing thereon. Further, biogas generated in one or both of the first anaerobic chamber and the second anaerobic chamber may be purified in a first stage using a water scrubber to remove a majority of the carbon dioxide and other contaminants from the biogas, and in a second stage using a pressure swing adsorption unit to reduce carbon dioxide and other contaminants to pipeline acceptable levels. Further yet, carbon dioxide and hydrogen sulfide gases generated during the biogas purification process may be injected into a water-containing chamber in the presence of bacteria and oxygen to convert the hydrogen sulfide to elemental sulfur and/or sulfate.
摘要:
Integrated processes for the conversion of hydrocarbons to C2 and C3 unsaturated hydrocarbons include combustion and cracking of hydrocarbons, dry oxidative reforming of methane, and catalytic hydrogenation of acetylene. Reactive products formed among the integrated processes may be distributed and recycled among the processes for the conversion of the hydrocarbon feedstock.
