Device for injecting and mixing a reactive fluid in high pressure ldpe processes

Abstract

The invention relates to a device (100) for injecting and mixing a reactive fluid in a flow of a process fluid for the preparation of polyolefins, comprising: an annular part (101) having an outer wall and an inner wall (102), wherein the annular part (101) is arranged for having a flow of the process fluid in a transport direction (F); a support structure (103) connected to the inner wall (102) of the annular part (101); an injector part (104) mounted on the support structure (103), wherein the injector part (104) is cylindrically shaped and wherein the cylindrical axis A-A′ of the injector part is parallel with a central axis of the annular part and is in the central part of the annular part (101); wherein the injector part (104) comprises a nozzle (105) for injecting the reactive fluid, disposed at a downstream side of the injector part relative to the transport direction (F); a supply channel (106) extending from the outer wall of the annular part (101) through the support structure (103) to the nozzle (105) of the injector part (104), and wherein the annular part (101), the support structure (103) and the injector part (104) are made from a single piece of metal.
