I dont know any rule of thumb with regard to minimum distance of an elbow from the inlet nozzle. But it should be selected on the basis of the inlet flow characteristics.

Inlet piping including the elbows can affect the efficiency of a separator by changing the flow characteristics such as flow regime, droplet size distribution, etc. It should be calculated on case by case basis considering the flow rates, GOR, velocities, etc.

In addition to the RichS29 answer separator designer should also consider nozzle size, velocity and momentum.
