    摘要: A method for recovering sulfur from a sulfur-bearing process gas stream in which a process gas stream comprising H2S and/or SO2 is contacted with a lean mixture of a lean UCSRP solution and a catalyst for promotion of a reaction between H2S and SO2 in anon-UCSRP vessel at a temperature below which H2S and SO2 react, whereby at least a portion of the H2S and/or SO2 is absorbed by the lean UCSRP solution, forming a rich mixture of a rich UCSRP solution and the catalyst. The rich mixture is introduced into a UCSRP vessel and heated to a reaction temperature greater than or equal to a melting temperature of sulfur, forming elemental sulfur and H2O.

    摘要: Adsorbent pellets coated with an outer nano-porous layer can be loaded with gas at loading pressures of 250 bar or greater, enabling a much higher loading than can be achieved at low pressures. The nano-porous layer provides nano-valves which can be sealed with an adsorbate such as ethanol or a hydrocarbon to close the nano-valves. The closed nano-valves maintain the high loading pressure inside the adsorbent pellets, and thus maintain the gas loading, during storage of the loaded nano-valved adsorbent pellets at much lower pressure. To release the gas, the nano-porous layer can be heated to a temperature sufficient to vaporize the adsorbate and open the nano-valves.

    摘要: An exemplary embodiment can be a process for sweetening natural gas to liquefied natural gas specifications. The process can include providing a membrane contactor having a lumen side and a shell side. A feed natural gas is introduced to the lumen side of the membrane contactor. An absorption solvent is introduced to the shell side of the membrane contactor. CO2 and H2S are removed with the absorption solvent from the feed natural gas resulting in a sweetened natural gas containing less than 50 ppmv CO2 and less than 4 ppmv H2S. Corresponding or associated systems for such sweetening of natural gas are also provided.
