Distillation process for removal of methyl acetylene and/or propadiene from an olefin stream |
摘要 |
The present invention provides a process for removing methyl acetylene and/or propadiene from a propylene stream and/or a butylene stream by two step fractionation. Methyl acetylene and/or propadiene avoids the use of a hydrogenation reactor and makes the methyl acetylene and/or propadiene recoverable from the process.
