Spray Nozzle Entrainment from Packings and Grid at Deep Vacuum

The main goal of this project is to compare the amount of spray nozzle liquid re-entrainment for various low surface area packings/grids, and to help fractionation specialists choose the optimum packing type to minimize wash oil wetting loss.  FRI is collaborating with a spray nozzle manufacturer to test one of their new to market nozzles.
