    摘要: 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—avoiding any re-engineering time and costs. The iron oxide-based materials can also be useable against other impurities, providing a single bed solution.

    摘要: 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 loaded 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.
