    • Systems and methods for separating one or more olefins are provided. In one or more embodiments, the method for separating one or more olefins can include separating at least a portion of one or more C 3 and heavier hydrocarbons from a hydrocarbon containing C 1 to C 20 hydrocarbons to provide a first mixture that can include methane, ethane, ethylene, and/or acetylene. At least a portion of the first mixture can be hydrogenated to convert at least a portion of the acetylene to ethane and ethylene. At least a portion of the methane can be separated from the hydrogenated mixture to provide a second mixture that can include ethane and ethylene. At least a portion of the ethylene can be separated from the second mixture to provide a first product that can include at least 95 mol% ethylene and a second product that can include at least 95 mol% ethane.
    • 提供了分离一种或多种烯烃的系统和方法。 在一个或多个实施方案中,分离一种或多种烯烃的方法可以包括从含有C 1至C 20烃的烃中分离出一种或多种C 3和较重烃的至少一部分,以提供可包括甲烷,乙烷,乙烯的第一混合物 ,和/或乙炔。 第一混合物的至少一部分可以被氢化以将至少一部分乙炔转化为乙烷和乙烯。 可以将甲烷的至少一部分与氢化混合物分离,以提供可包括乙烷和乙烯的第二混合物。 可以将乙烯的至少一部分与第二混合物分离以提供可包含至少95mol%乙烯的第一产物和可包括至少95mol%乙烷的第二产物。
