EESIFLO International is an original manufacturer of highest
quality static mixers for the oil and gas industry. We specialize on applications
which involve crude oil mixing for the determination of water content
in pipelines, desalting crude oil with water, diluting and mixing of additives
into liquids such as gasoline or fuel oil or simply adjusting the viscosity
of heavy fuel with gas oil. Static mixers are also important for any application
that requires mixing of two or more fluids in the same stream.

and water into a homogeneous mixture
How our static mixers do the job?
A small amount of energy is required to adequately mix oil and water in
a pipeline using conventional shear, reverse flow and collision to produce
a homogeneous mixture of water droplets and oil droplets downstream of
the mixing element with minimal net pressure drop. Static mixers have
no moving parts and are virtually maintenance free. Using the energy available
from the fluid in the pipeline and calculating the number of elements
required for mixing enables clients to achieve truly mixed liquids at
the mixer’s outlet.
Application Examples
An example of a typical application could include custody transfer mixing
.It is a well known fact for example, that static mixers are an absolute
requirement for crude oil sampling. The same applies to water cut measurements
in large pipes, irrespective of the technology involved one of the main
problems is density differences between oil and water. This problem manifests
itself in bottom water flowing at the base of the pipe. Although a inline
permittivity measuring device may measure the complete annulus of liquid
in the spool piece used, slugging, particularly at low flow rates can
cause severe separation of oil and water which cause errors in sampling
and measuring instruments since the sampling or watercut analyzing is
non representative without mixing.

The EESIMIX inline mixer are supplied in sizes 1 inch to 48 inches and
in pressure ratings from 150 ANSI to 2500 ANSI. The mixers can be fabricated
in carbon steel, stainless steel or Duplex. Each unit is factory pressure
tested and weld inspected to conform to international standards. Each
mixer is designed and manufactured to meet the task required by the application
. Mixers can be supplied with optional ports and connections , bypass
loops , grab samplers , watercut meters or specific analytical instrumentation.

More about EESIMIX static mixers
EESIMIX Static mixers are a row of carefully designed
fixed mixing elements permanently welded within a pipe . The mixers use
the full force of the process flow stream to enable mixing between two
or more fluids. EESIMIX's design of static mixer creates very little pressure
drop and the greatest amount of mixing . Our mixers are also used in blending
processes as well as crude oil mixing. Static mixers are also called "motionless
mixers" This is because the mixing is done by permanently affixed
mixing fins, obstructions, or channels mounted in pipes, designed for
promoting mixing as fluid flows through the mixer. The criteria for using
motionless mixers is to achieve homogeneity of composition in a liquid
without the need for external process mixing, which can be very costly
and often questionable. When sizing/designing a static mixer there are
two main factors to consider .The velocity at which a mixer can process
materials, also known as its flow rate, is a rated measurement based on
the volume of product the mixer can process during given period of time.
If the flow rate is known, it is possible to calculate the number of mixing
elements required to produce a homogeneous mixture. A good example is
water and oil. Water and oil do not mix readily and in a process stream
will tend to separate out. This phenomena worsens as the watercut increases.
Placing a probe in the centre of the pipe to retrieve a crude oil sample
for a sampling system or BS&W monitor will not give meaningful results
without static mixing. This has been proven time and time again over the
years both in the field and in laboratory simulations.
