1. An initiator injection nozzle for mixing an initiator with a process fluid, comprising a body comprising:
a process fluid inlet port to receive the process fluid and an outlet port;
a process fluid flow passage through which the process fluid traverses along a process fluid central flow axis between the process fluid inlet port and the outlet port, the process fluid flow passage being defined by the body and having a constricting portion, a throat and an expanding portion in that order from the process fluid inlet port to the outlet port, thus forming a Venturi-type process fluid flow passage;
an initiator inlet to receive the initiator and an initiator outlet; and
an initiator fluid flow passage through which the initiator traverses along an initiator central flow axis between the initiator inlet and the initiator outlet, the process fluid flow passage intersecting the initiator fluid flow passage at the throat;
wherein at least one elongated vane having a leading end and a trailing end is provided within the process fluid flow passage and extends along the process fluid central flow axis,
wherein the initiator outlet is disposed on a surface portion of an axial edge of the vane.
