Vertical style gas liquid separators are used when the flow path
involves traveling vertically upwards or downwards. Our vertical
centrifugal separators will remove entrained droplets
and particles larger than 10 microns with 99% efficiency. The most
common and inexpensive vertical gas liquid separator consists of a
cylindrical pressure vessel having an inlet and outlet 180° apart
(in-line) in addition to a vent and drain port. The centrifugal baffle
assembly is always located at the inlet side of the centrifugal
As illustrated, the air, steam or gas enters the separator and flows around a
slotted baffle which induces a vortex, exerting centrifugal force on
entrained droplets and particles.
The resulting reduction in velocity and inertia causes most droplets
larger than 10 microns to impinge on the
baffle or vessel walls and due to gravity, coalesce to the low point of
the vessel for drainage.
Automatic drainage without any loss of
air, steam or gas can be accomplished with a
The liquid removal capacity for the unit
illustrated is equivalent to 10% of the
separators maximum weight-flow capacity. The removal
capacity doubles to 20% for designs having inlet and outlet nozzles
tangential to each other due to the increased complexity of the
torturous path the process gas must pass through to exit the gas liquid
Another type of vertical separator is an
, which are not pressure vessels because they are
installed at the end of a vent pipe to atmospheric pressure.
Exhaust heads reduce the opacity of the vented gas, reducing carry-out
and enabling reclamation of treated fluid.
