BTG is the proud winner of this year’s ATIP Innovation Gold Prize. The award was received for the TCR-2512/2502 “Peak TOTASH In-line transmitter for measurement of total consistency and ash content”.

In pulp preparation, for the consistency range of 0.5 to 14%, current technology uses different measuring principles:

* Total consistency by optical or microwave principle: in-line measurement
* Ash content by optical (depolarized retro-diffusion) principle: on-line measurement
* Consistency by shear-force principle (rotating or blade):  in-line measurement The measurement of total consistency and ash content hence necessitates the use of several measurement probes.

BTG’s innovation TCR-2502 / TCR-2512 use one unique measurement principle to very precisely and separately evaluate:
* Total consistency in the range of 0.5 – 12%
* Filler content in the range of 1 – 70%
* Fiber consistency in the range of 0.4 – 10%.

This method is applicable in each step of the papermaking process. The technology allows financial gains of 50 up to 300 k€ per year: from the pulper to the machine chest for pulp, waste water and slurries

Some examples:
* After the pulper:  filler control through raw material selection
* Waste water treatment, deinking:  productivity optimization through filler content management
* Refining:  energy savings through precise and true calculation of the specific energy on the fiber
* Mixing chest:  precise substitution of fibers by filler. Improved use of broke through the control of filler content
* Headbox:  reduced basis weight variation
* Effluent treatment:  precise evaluation of fiber loss and slurry optimization
