What methods are used to size air assist blowers for flare stacks (assuming smokeless design)?

[Bobby Strain]

One provides a duty specification to vendors of such equipment.

[KeJoSa2010]

How do you determine the required duty for smokeless design? Smokeless design depends on the Ringlemann number requirement. Some regulations require Ringelmann 1 (20% opacity) while others require Ringlemann 0 (0% opacity). Are there methods to calculate the air required to produce a particular Ringelmann number given the flare gas composition/flow rate. This isn't so straight forward because there are so many factors (i.e., tip efficiency, background lighting, light scattering, etc.).

 

This is something I am being asked to do. I can't find much in the literature and obviously vendors have proprietary methods. Are there general methods to estimate the blower duty?
