METHODS AND SYSTEMS FOR SEPARATING OLEFINS |
摘要 |
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 C3 and heavier hydrocarbons from a hydrocarbon containing C1 to C20 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. |

1. A method for separating one or more olefins comprising:
separating at least a portion of one or more C3 and heavier hydrocarbons from a hydrocarbon comprising C1 to C20 hydrocarbons to provide a first hydrocarbon mixture comprising methane, ethane, ethylene, and acetylene; hydrogenating at least a portion of the first hydrocarbon mixture to convert at least a portion of the acetylene to ethane and ethylene; separating at least a portion of the methane from the hydrogenated mixture to provide a second hydrocarbon mixture comprising ethane and ethylene; and separating at least a portion of the ethylene from the second hydrocarbon mixture to provide a first product comprising at least 95 mol % ethylene and a second product comprising at least 95 mol % ethane, wherein the ethylene is separated from the second hydrocarbon mixture at a pressure of about 360 kPa to about 4,000 kPa. |
