Continuous On-Line
Particulate Analyzer to meet Process and Environmental demands
Aladdin is the On-Line
system, for comprehensive analysis of particulate in a process stream developed
by Ankersmid.
Designed to operate in
most hostile environments, the Aladdin is able to analyze and differentiate
between particulate in a live process stream. Oil droplets and suspended solids
in a produced water stream can be analyzed by type, size and total content. The
Aladdin Oil content analyzer is the cost-effective solution to the problem of
continuously and accurately measuring particulate concentration and size
distribution of all bodies in a stream.
There are a wide range
of process and environmental applications for the Aladdin such as
Oil/particulate monitoring of offshore produced water; Particulate monitoring in
water injection systems; oily bilgewater on ships and refinery discharge water
systems.
The measuring method
does not require regents or solvents and thus complies with current legislation
banning the use of CFCs and Ozone depleting chemicals.
Aladdins working end
has been designed for robust automated sampling at online conditions, virtually
maintenance free separation and can be housed in an Explosion Proof enclosure
certified for zone 1 hazard class area. In addition, The Aladdin can analyze
streams with high temperatures and pressures.
Operating
Principle
The Aladdin operates
on the well proven principle of Time of Transition Theory (TOT). The process
stream is passed through a measurement cell where particles are scanned by a
focused near infrared laser beam. The beam is rotated at constant speed within
the measuring area by a wedge prism. At the angular velocity of the beam is
know, the size of each individual particle can be calculated from the duration
of the signal obscuration caused by the particle.
Each particle is
examined discretely, producing a signal from the detector. The signal duration
is related to the size of the particle and the signal duration is related to the
sizes of the particle and the signal shape is related to the size of the
particle and the signal shape is related to density, shape and optical
characteristics.
The interaction
signals are transmitted to a computer in the control room where final
calculations and display of the ppm count data, size distribution and alarm
annunciation is executed.
Sophisticated pulse
analysis algorithms are employed to reject out of focus and off center
interactions and to distinguish between randomly shaped suspended solids and
spherical oil droplets.
The strength of the
Time of Transition technique is that it relates solely and directly to particle
size rather than to secondary properties. This eliminates inconsistencies due to
refractive index, viscosity variations and thermal convection.
Moreover, the Aladdin
also offers as an option, the unique perspective of visualization and shape
analysis. The shape analysis channel uses a CCD video camera microscope and
illumination is provided by a synchronized strobe.
Independent tests have
been carried out by Orkney Water Test Center- demonstrating the outstanding
performance of the product.
