PVS (Vacuum Dehydration)
Compared to Other Technologies
Centrifuge units–
Removes free water only; has
difficulty breaking stable emulsions; larger envelope
dimensions but lower flows; higher initial and
operating costs.
Desiccant units–
Have limited water removal
capability due to absorbing material; only removes
air ingressed particles; expensive compared to the
volume of water removed.
Coalescer units–
Removes free water only; has
difficulty breaking stable emulsions; does not work
well in viscous fluids (>100 sus); much larger in size
compared to PVS.
