RE: Flare: smokeless operation with blower
Aromatics generally have a very low "cracking" temperature (as a function of the energy of formation) and so they start making free carbon quite early in the flame. (olefins and acetylenes too).
Attacking these with an air assisted flare seems like a good idea but it is very difficult because the oxygen speeds up the combustion and raises the flame temperature which causes the carbon to start forming even sooner. Eventually, unless you get an extremely good mix of air and gas, and use something approaching stoichiometric air (check out the potential volumes !!), you could be on a loser.
In my view, you would be better off using a steam assisted flare because the steam cools the flame and delays the "cracking". There are a couple of good designs on the market which also have steam/air eductors built into the tip, and give you some air as well. The combination will be more effective than just air.
Let me know if you need to follow up commercial ideas.
