Separation Internals - Mist Eliminators


The professionals at Sepco Process Inc. size, select, and provide
filtration, separation, and coalescing equipment to meet our
customers needs.


Mist Eliminators: Mesh Pad

Sepco Process Mesh Pads collect and remove droplets through impingement on the
our wire mesh. Typically removing droplets of 3 microns. The
collected liquid then drains by gravity to the bottom of the
vessel.

Mesh pads: Sepco Process’ mesh pads can be made of any material
which is ductile enough to be drawn into wire. Although Sepco
Process supplies 300 stainless series mesh as a standard, many
other materials including Monel, Inconel, Alloy 20, duplex
stainless and nickel are available upon request. A Mesh pad may
be more prone to plugging than other tower internals but it
offers excellent efficiency.

Our mesh pads are fabricated to meet virtually any vessel
geometry and orientation with Sepco Process’s designers
determining the size and style of mist eliminators required to
meet or exceed our customer’s process requirements and
specifications.


Mist Eliminators: Vanes

Vanes are used for the separation of liquid from gas. These vane
type mist eliminators have lower efficiency but are less prone
to plugging than standard meshpads. Sepco Process designs and
supplies many types of vanes, including:

  • Standard Vane
  • Pocket Vanes
  • Hook Vanes

Axial Cyclones

Axial Cyclone Swirl Tubes are offered for high performance
applications. They are an excellent choice for applications
having high operating pressure and high fowling cases. The Axial
Cyclones offer performance which in many cases cannot be
achieved with a standard mesh pad or vanes.

As added benefit, Axial Cyclone Swirl Tubes can also
significantly decrease vessel diameter and maintain design
efficiency!

Multi-Cyclones

Multi-Cyclones are generally used as single stage liquid/gas
separation devices where solids or high levels of liquid are
expected. This design provides excellent performance of
entrainment separation at high gas capacities at pressures from
10 up to 200 bar.


Gas Filtration

  • Coalescer Elements & Vessels

Inlet Devices:

Sepco Process has four types of inlet devices including the Pipe-
Distributor, the Wedge-Type Diverter, the Vane-Type Diffuser,
and the Cyclone Inlet Diffuser.

Selection of the appropriate application is dependent on the
momentum of the incoming feed. Simultaneously, Sepco Process inlet
devices will smooth out the flow through process vessels and
allow only fine liquid droplets to confront the mist eliminator
element, thus providing greater process capacity and efficiency!


Seporator Internals

Sepco Process Specializes in designing and supplying coalescers
in Seporator vessels including: 2 phase (gas/liquid), 3 phase
(gas/liquid/liquid) applications. We offer numerous coalescing
and separation products including:

Coalescers: Knitted wire Coalescers, Parallel
Plate Coalescers, and Corrugated Plate Coalescers.

Foam Breakers: Often crude oil exhibits moderate
or severe foaming tendencies, which can be problematic for
separation internals installed in Production Separators, Slug
Catchers, and Free Water Knock-Out Drums. To relieve this
problem, Sepco Process Inc. supplies both traditional foam
breaking internals and state-of-the-art, next-generation Inlet
Cyclones, depending on the application. The Inlet Cyclone design
eliminates foam related problems by utilizing cyclonic action,
high G-forces, and thus, efficiently breaking down incoming foam
to liquid and gas phases.

Motion/Calming Baffles: Oil production on
floating platforms brings about unique problems. Because of
extreme wave action, separation of oil, water, and gas can be
difficult as the three phases tends to mix within the production
vessels. Sepco Process Inc.’s baffle design helps in dampening
the wave motion and to minimize the mixing of the three phases,
even in the greatest of storm conditions.
