摘要： A highly cost-efficient method and process for producing oxygen from a gaseous mixture such as air results in substantial energy savings compared to conventional methods. The gaseous mixture is fed to a membrane absorber in which oxygen from the gas is absorbed, through a first membrane by an oxygen-absorbing liquid that possesses suitable absorption and desorption properties. The resulting oxygen-rich carrier liquid is fed to a membrane desorber in which oxygen from the liquid is desorbed through a second membrane, suitably with the aid of a vacuum. The oxygen product suitably has greater than 95% purity, or greater than 99% purity.

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： A process for removing carbon dioxide from a carbon dioxide-loaded solvent uses two stages of flash apparatus. Carbon dioxide is flashed from the solvent at a higher temperature and pressure in the first stage, and a lower temperature and pressure in the second stage, and is fed to a multi-stage compression train for high pressure liquefaction. Because some of the carbon dioxide fed to the compression train is already under pressure, less energy is required to further compress the carbon dioxide to a liquid state, compared to conventional processes.

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.

摘要： A multi-stage process for recovering acid gas from natural gas having high acid gas contents utilizes two or more membrane absorption contactors arranged in series. The first membrane absorption contactor uses a physical solvent to remove a high volume of acid gas transferred across a membrane, and to reduce the acid gas content in the natural gas to a lower level that can be managed using chemical solvents. The second and, if needed, subsequent membrane absorption contactors can use a chemical solvent to remove acid gas transferred across the respective membranes and reduce the acid gas content in the natural gas to very low levels, if needed, depending on product specifications.

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.
