– Liquid separators & coalescers for vertical and horizontal
quality design and engineering expertise gained over many years
involvement in the oil, petrochemical and chemical industries
provides a sound basis for selection and process design of an
extensive range of separators, mist eliminators, coalescers and
range of liquid-liquid separators & coalescers are for horizontal
or vertical vessels to increase the efficiency of separation between
two liquid phases that are unable to mix. The aim being to reduce
the loss of expensive products, increase the purity of each phase,
stop corrosion and downstream equipment and reduce pollution to
the surrounding environment.
Throughout continued cooperation with university research institutes
Costacurta is able to develop fluid-dynamic studies for the optimization
of design, sizing and performance.
- Sloped plate coalescers
are effective for the separation of droplets usually greater than
30 microns, widely used in onshore and offshore extraction and
treatment plants for natural gas and oil. These enable the use
of smaller vessels, compared to those with out any type of internals.
Also they are not very sensitive to clogging.
from several layers of special crinkled wire mesh arranged to
give a coalescent effect cellular structure. Main function is
to favour an increased in droplet size of a liquid phase dispersed
in another continuous phase that cannot be mixed with the former.
The droplets enlarged by VICO-Tex® coalescers can then easily
be separated by gravity in the settling zone downstream of the
coalescer. VICO-Tex® coalescers are effective for enlarging
droplets of a diameter of less than 30 microns.
feed inlet distributor
- Gas-Liquid vane feed inlet distributors are made
of specially shaped vanes, which are appropriately sized
to break up the vapour stream entering a vessel into a number
of partial streams. They thus enable pre-separation of the
liquid present in the gas and, above all, an even distribution
of the gas over all the vessel section. Installing a vane
feed inlet distributor normally reduces the space needed
for even distribution of the gas.
- Straightners Are made up of specially
designed parallel vanes to break up the vapour stream passing
through them into a number of partial streams. They thus
give pre-separation of the liquid present in the gas and,
above all, an even distribution fo the gas over all the
vessel section reserved for the latter. They also act on
the surface of the liquid by removing foam and breaking
waves. They are normally installed in horizontal vessels
in the presence of at least one liquid and one vapour phase.
They are positioned between the VICO - Pack sloped plate
coalescer (if present) and the droplet separator (VICO -
Vane or VICO - Spin) under the gas outlet nozzle.
most frequently used in construction of the above are stainless
steels and some special alloys such as Monel, Inconel, Incoloy,
Hastelloy and Carpenter 20 and pure Titanium.
