Time for condensation to take place

[tbecht]

Is there a calculation for the time it take heavier hydrocarbons (C4+) to coalesce and fall out as oil?

At best it would be a statistical average that doesn't help much with an individual situation. I've seen vapors super saturated for many minutes and miles down a pipe. I've also seen condensation prior to the dew point. Any of these numbers are useful averages for a population, and individual results may vary. If I know that a gas stream cannot stay super saturated forever, then I know that I have to deal with condensation. If I know that it can stay super saturated for a while, then I know I have to deal with condensation in the gathering system. Much more than that and you are working outside the accuracy of the calculation.

At any given point in time there will always be a C4+ condensing and one evaporating, in equilibrium

If you want to maximize the rate toward making liquids, use a coalescing filter separator. Oh, technically, the liquid is called condensate, not oil.

The same time it takes to lose their latent heat of condensation.
