Dilute Vapor-Vapor Mixing

Dilute Vapor-Vapor Mixing

(OP)
Vapor-vapor mixing is often taken for granted, with a flush nozzle or nozzle shroud often considered adequate for most applications.  However, I am working on a problem where a vapor stream must be fed to a reactor very well mixed.  Unfortunately, the reactants must be mixed for a minimum residence time due to side-product formation.

My reactant streams, a 1.1 barg stream with volume 13,000 cu.m/hr and a second 900 m^3/hr stream at 2.5 barg.

We were hoping to use an eductor as a mixing device, but vendors have come back saying that there is not enough flow/pressure on the motive side, though we are not looking for any pressure increase.  Any bright ideas out there?

Also, has anyone seen a quantitative measure for "degree of mixing?"  It is hard to compare the several competing technologies with no quantitative measure or calculation.
