Abstract

A process for continuously mixing at least two fluid streams and splitting the stream of the mixture into at least two partial streams, comprising a) providing streams of the at least two fluids via separated conduits; b) combining the streams of the fluids and forming a homogeneous mixture; c) measuring the pressure in the conduit conveying the mixture of the fluids; d) splitting the stream of the mixture of the fluids into at least two partial streams and feeding each of the partial streams to a conduit equipped with a flow control device controlled by a controller; and e) adjusting the flow rates of the partial streams of the mixture of the fluids by feeding the pressure information measured in step c) as process variable to the controllers controlling the flow control devices, a process for feeding a mixture of at least two fluids via at least two feeding points, an apparatuses for carrying out such processes and a process for polymerizing olefins.
