Abstract

The present invention relates to an initiator injection nozzle 1 for mixing an initiator with a process fluid. The initiator injection nozzle 1 comprises a body 10 comprising (i) a process fluid inlet port 11 to receive the process fluid and an outlet port 17, (ii) a process fluid flow passage 13 through which the process fluid traverses along a process fluid central flow axis 15 between the process fluid inlet port 11 and the outlet port 17, wherein the process fluid flow passage 13 is at least partially defined by a constricting portion 12, a throat 14, and an expanding portion 16, (iii) an initiator inlet 30 to receive the initiator and an initiator outlet 32, and (iv) an initiator fluid flow passage 34 through which the initiator traverses along an initiator central flow axis 35 between the initiator inlet 30 and the initiator outlet 32. The initiator injection nozzle 1 is characterised by a plurality of elongated vanes 20 provided within the constricting portion 12 and extending along the process fluid central flow axis 15, and in that each of the vanes 20 has a leading end 26, a trailing end 22 and a curved vane surface 21.
