Abstract: The present invention is concerned with a process for providing a homogeneous particle-containing slurry comprising the steps of: (a) providing a vessel comprising at least one impeller rotating around a vertical axis of the vessel, wherein a rotational speed n 1 of the at least one impeller is higher than n min according to equation (1), the vessel further comprising an inlet and an outlet; (b) introducing a particle-containing slurry into the vessel or introducing components forming the particle-containing slurry into the vessel; (c) rotating the at least one impeller at least around the vertical axis for homogenizing and/or maintaining a homogeneous particle distribution within the slurry; (d) withdrawing the homogeneous particle-containing slurry via the outlet; (e) reducing the rotational speed n 1 of the at least one impeller to a reduced rotational speed n red , whereas n red is lower than n 1 and higher or equal than n min according to equation (1):

Abstract: The present invention is concerned with a separator comprising a vessel, a first inlet, a second inlet, a first outlet, a second outlet, and a separation device located downstream of the first outlet, wherein the separation device comprises two outlets, whereas one outlet of the separation device is fluidly connected to the second inlet of the vessel. Furthermore, the present invention is also concerned with a process for separating hydrocarbons from a reaction solution comprising a polymer and said hydrocarbons, comprising the steps of passing the reaction solution through the first inlet into the separator according to the invention, withdrawing a first outlet stream through the first outlet, withdrawing a second outlet stream through the second outlet, separting the first outlet stream in the separation device to produce a first separated stream and a second separated stream, withdrawing the first separated stream from the separation device and passing the first separated stream through the second inlet into the vessel, and withdrawing the second separated stream from the separation device.
