The invention provides a process for removal of HCN and NHfrom synthesis gas, the process comprising the steps of: (a) contacting feed synthesis gas comprising HCN with a HCN hydrolysis sorbent in the presence of water, thereby obtaining synthesis gas comprising NH; (b) contacting the synthesis gas comprising NHwith an acidic cation exchange resin in the presence of water to remove NH, thereby obtaining purified synthesis gas.

Process for removal of hydrogen cyanide and ammonia from synthesis gas

The invention provides a process for removing COS and HS from a feed synthesis gas stream comprising COS and HS, the process comprising contacting the feed synthesis gas stream with solid adsorbent at a temperature in the range of from 100 to 240&#xb0; C. to remove carbonyl sulphide and hydrogen sulphide, thereby obtaining a purified synthesis gas stream, wherein the solid adsorbent comprises one or more metals or oxides of the metals or combinations thereof and the metals are selected from the group of Ag, Sn, Mo, Fe and Zn.

Process for removing carbonyl sulphide and hydrogen sulphide from a synthesis gas stream

The invention provides a process for the removal of COS and HS from a synthesis gas stream comprising COS and HS, the process having the steps of: removing HS from a feed synthesis gas stream with a first solid adsorbent to obtain a first synthesis gas stream, converting COS in the first synthesis gas stream to HS by contacting the first synthesis gas stream with a COS-hydrolysing catalyst in the presence of water in a hydrolysis zone to obtain a second synthesis gas stream depleted of COS and enriched in HS; and removing HS from the second synthesis gas stream by contacting the second synthesis gas stream with a second solid adsorbent in a HS removal zone to obtain a third synthesis gas stream depleted of HS and depleted of COS to very low levels.

A treating unit that comprises an absorber unit for contacting a regenerated solvent with a gas stream loaded with contaminants to yield a treated gas stream and a loaded solvent stream; a regenerator unit for stripping the loaded solvent stream to yield a loaded gas stream and the regenerated solvent; and a device for smoothing contaminant peak concentrations in the loaded solvent stream and for receiving the loaded solvent stream. The device comprises a first hold-up tank having a first inlet and a first outlet, a second hold-up tank having a second inlet and a second outlet, and an inlet distributor that is operatively connected to the first inlet and to the second inlet and that provides for directing flow of the loaded solvent stream to either the first hold-up tank or the second hold-up tank.

Treating unit for treating a loaded solvent stream having a time varying concentration of contaminant

A process for the reduction of carbonyl sulfide (COS) in a gas stream is described. It comprises contacting the gas stream with an iron oxide-based material. The present invention relates to the removal of COS from any type of gas stream, in particular those which include one or more of the group comprising ethane, methane, hydrogen, carbon dioxide, hydrogen cyanide, ammonia, hydrogen sulfide, and noble gases. These include natural gas, and in particular syngas. Syngas is useable in a Fischer-Tropsch process. The present invention provides a simple but effective process for the reduction of COS, especially with a material that can easily be located in existing guard beds&#x2014;avoiding any re-engineering time and costs. The iron oxide-based materials can also be useable against other impurities, providing a single bed solution.

Process for the removal of contaminants

The invention provides a process for treating a loaded solvent stream having a time-varying contaminant concentration, the process comprising the steps of: (a) providing a plurality of hold-up tanks; (b) feeding the loaded solvent stream in dependence on its contaminant concentration to one or more of the hold-up tanks and; (c) allowing lowed solvent to flow from the plurality of hold-up tanks to obtain a smoothed loaded solvent stream having a reduced time-varying contaminant concentration. The invention further provides a treating unit comprising a circuit for circulating a solvent stream, which circuit includes a device for smoothing contaminant peak concentrations, said device comprising a plurality of hold-up tanks each hold-up tank having at least one inlet and an outlet equipped with an outlet valve, the device further comprising an inlet distributor allowing the control of solvent flow to one or more of the hold-up tanks.

Process for treating a loaded solvent stream having a time-varying concentration of contaminant

The invention concerns a process for the removal of sulphur compounds from a hydrocarbon stream, especially a gaseous hydrocarbon gas stream, comprising said sulphur compounds, which process comprises contacting said gas stream with an adsorbent comprising a zeolite having a pore diameter of at least 5 &#x212b; to adsorb the sulphur compounds thereon, the adsorption process followed by a regeneration process of used, loaded adsorbent by contacting the said loaded adsorbent with a regeneration gas stream having a relative water humidity less than 100%, especially less than 80%. Suitably the regeneration is followed by a dry regeneration treatment. The invention further relates to a process for the regeneration of adsorbent comprising a zeolite having a pore diameter of at least 5 &#x212b; loaded with sulphur compounds by contacting the adsorbent with a regeneration gas stream having a relative water humidity less than 100%, especially less than 80%. Suitably the regeneration is followed by a dry regeneration treatment.
