摘要:
The present application concerns a process for the removal of hydrocarbons from an aqueous stream, which process may include conducting a phenol-containing water stream into a separation column, separating the phenol-containing water in the column using heat to form an overhead portion and a bottoms portion, and collecting the overhead portion as well as the bottoms portion. Further, the process may include adding an eluent to an aqueous stream, thereby forming an aqueous mixture, subsequently conducting the aqueous mixture into a separation vessel, wherein it is allowed to settle into two phases, which form a hydrocarbon stream and a phenol-containing water stream, subsequently collecting the hydrocarbon stream, and conducting the phenol-containing water stream to the separation column for further separation.
