Two phase flow, a potential momentum problem in distributors.

Working with Shell Schoepentoeters™, we learn how the efficiency of any equipment working with two phase distributors can be reduced by the momentum.
In any case, equipments with distributor working in two phase flow will improve its performance If we keep as long as possible the inlet line in a vertical plane.

The Huge Sloped and welded equipments case

Take care if big equipments shall be installed with slope and also shall be welded together in site (as Sulphur reactor with Waste heat boiler).
For instance, large diameters as nine feet, with a slope of one degree create a top projection in the highest equipment (and also a bottom projection in the lowest equipment) of almost one inch. If by mistake the highest equipment will be early installed, erection contractor will found an overlapping of almost two inch (usually they will claim by a foundation mistake)
