Accurate Pulp Mill Consistency Measurement Required

The graph above displays the actual
results from lab verification samples
taken from the defiberlizer.

Problem / Issue:
Pulp Mill Consistency Measurement Requires Accurate Measurement over a Wide Range of Consistency Levels.

Overview:
The overall throughput (TPD) of the fiber line is traditionally calculated from a single consistency measurement device. This measurement must be accurate and repeatable.

TECO Solution:
C9700 Fixed Wing Consistency Sensor.

How the TECO Solution Solves The Problem...
The TECO C9700 Fixed Wing Consistency Sensor is designed to accurately measure over a wide consistency range, including low consistency swings from variations in blow tank levels. This sensor has proven consistency ranges from 1.5 % to 7.0%, over a wide range of velocity (flow) rates.

As an example, the above graph displays the results from a southern kraft pulp mill application, after the blow tank, prior to the defiberlizer.

Benefits

• Wide Consistency Range – accurate across a variety of consistency levels
• Simple / Reliable Probe Design – no moving parts or maintenance issues
• Stable Calibration and Excellent Repeatability – for complete consistency control

Who is it Important to?

• Pulp Mill Superintendent
• Bleach Plant Superintendent 
• Process Control Engineer
• Maintenance Manager
• Instrument Superintendent

TECO HK Series Microwave Consistency Transmitter Technical Review

TECO HK Series
Microwave Consistency Transmitters

The TECO HK Series microwave consistency transmitters provide a versatile, safe and easy-to-calibrate means for measuring the consistency of paper stock. The HK Series can successfully measure broke, recycle or other difficult fiber types, independent of fiber length, freeness or wood species.

Typically less than half of the cost of other microwave transmitters, the HK series microwave transmitters will measure the percentage of total solids of additives in water and percentage of moisture in wood chips with the same transmitter. Applications include measurement and control of machine, recycle & broke stock, measurement and control of % totals solids of starch additives, measurement and control of % solids (limestone, kaolin clay) in coatings.

• Low cost – typically less than half the cost of other microwave transmitters
• Easy to install
• One point calibration
• Adjustable antenna units to maximize sensitivity to process conditions
• Internally compensated for temperature
• No routine maintenance required. Install & forget!
• Current and Digital Outputs
• Contact closure
• Versatile – Same transmitter can be used in Pipes, tanks, chests, belts & chutes.

Applications:

• Paper and Board Mills:
  • Machine Stock Consistency Measurement and Control
  • Broke Consistency Measurement and Control
• Paper Mills
  • Bleaching State Feed Consistency
  • Consistency Measurement & Control in Fiber Lines with changing Wood Species
  • Production Measurment at Integrated Mills
• Mechanical Pulp Plants
  • Refiner Consistency
  • All Fiber Line Consistency Measurments and Control
• De-inking Pulp Plants
• Consistency and Control of Deinking Pulp
• Production Measurement of Deinking Pulp

TECO HK Series Microwave Consistency Transmitter Technical Review from Thompson Equipment Company

Stop Spending Money on Process Instruments Unnecessarily

Restore process instruments
to "better than new".

Millions of dollars each year are spent unnecessarily throwing away old flowmeters and process instruments. Companies aren't aware of a cost-effective alternative that doesn't impact product performance or quality. That alternative is "remanufacturing" - a process that restores process instrumentation to factory specifications and many times provide a "better than new" instrument - at a fraction of the cost of buying new.

TECO, based in New Orleans, established a strong reputation and very loyal customer base becoming the world's largest "remanufacturer" of flowmeters and many other types of process instruments.

Their business model and process is unique and elegantly simple. You send your flowmeter or instrument to TECO along with your contact information. Within 48 hours, TECO diagnoses the overall condition and outlines the problems with your device, and provides a quote for the restoration. If unrepairable, they quote a stock "remanufactured" direct replacement. If they can't restore, or provide a remanufactured unit from stock, they will competitively quote a new replacement.

Their repair / restoration process is top-notch. Experienced TECO technicians tear down the item and begin rebuilding it from the ground up. Parts are disassembled, cleaned, sandblasted, painted, and re-assembled. Electronics are repaired or replaced and then fully tested to factory specifications. The unit then goes through a NIST traceable calibration from a ISO/IEC accredited lab and all documentation is recorded and provided.
