The present invention relates to a group and method for the separation of a mixture comprising two fluid phases mutually at least partially immiscible and with different specific density characterized in that it comprises a closed chamber (11) which extends between an upper outlet mouth (12a) of a fluid phase with lower specific density separated from the mixture, positioned at a first upper height, and a lower outlet mouth (12b) of a fluid phase with greater specific density separated from the mixture, positioned at a second lower height with respect to the first upper height, an inlet (15,33) for said mixture inside said closed chamber (11) also being present at a height interposed between said upper and lower heights, a first upper gross separation device (13) of said mixture and a second lower fine separation device (14,14') of said mixture, hydraulically connected to each other (13) (14), being situated in succession, inside said closed chamber (11), between said upper outlet mouth (12a) and said lower outlet mouth (12b), the first upper gross separation device (13) comprising a gravitational separation chamber and the at least second lower fine separation device (14,14') comprising at least one coalescence separator (14) and/or at least one hydrocyclone separator (14').

Abstract
The present invention relates to a group and method for the separation of a mixture comprising two fluid phases mutually at least partially immiscible and with different specific density characterized in that it comprises a closed chamber (11) which extends between an upper outlet mouth (12a) of a fluid phase with lower specific density separated from the mixture, positioned at a first upper height, and a lower outlet mouth (12b) of a fluid phase with greater specific density separated from the mixture, positioned at a second lower height with respect to the first upper height, an inlet (15,33) for said mixture inside said closed chamber (11) also being present at a height interposed between said upper and lower heights, a first upper gross separation device (13) of said mixture and a second lower fine separation device (14,14') of said mixture, hydraulically connected to each other (13) (14), being situated in succession, inside said closed chamber (11), between said upper outlet mouth (12a) and said lower outlet mouth (12b), the first upper gross separation device (13) comprising a gravitational separation chamber and the at least second lower fine separation device (14,14') comprising at least one coalescence separator (14) and/or at least one hydrocyclone separator (14').I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
