Customer and Case
The Pajaritos Petrochemical plant is located in Veracruz, Mexico.
Pajaritos was owned and operated by PEMEX since 1967 until it was sold to
Mexichem in 2013.
Produces Ethylene , Vinyl Chloride and Hydrochloric Acid among other things.

Application - Customer Motivation
Hydrochloric Acid is used in as a
chemical reagent in the large-scale
production of vinyl chloride for
PVC plastic
At concentrations above 40%, the
evaporation rate is much higher
To minimize evaporation losses,
the HCL is pressurized and cooled
The subfreezing temperatures
create an ice build up issue that
can lead to failure of an in-line
meter
Reliable measurement is critical to
the daily operation of the plant, a
loss of the flow measurement will
result in a shut down of the plant

Application - Measurement Point
Measuring point is located in the Chlorinated Plant
Fluid is maintained at a temperature below -38C̊
Pipe must be fully insulated, any exposed surfaces are subject to ice build up.

Solution - Installation
A single Channel 7407 with Stainless Steel enclosure was used
Paired with FLEXIMs WaveInjector Extreme Temp Mounting Fixture, measurement
of the medium was not an issue
The patented mounting fixture thermally separates the ultrasonic transducers
from the cold pipe

Customer Benefits
Customer no longer has to worry about device failure due to ice build up
No more clogging or pressure drops
WaveInjector equipment can be insulated over and up to the sensorbox
Continuous spraying of steam to reduce ice build up will not be needed like on
the DP
Maintenance free device
The process was not stopped for the installation!
