CMS - Chip Monitoring System (NEW)

A NEW PRODUCTS (designed for Digester control)

Chip Management System (CMS) provides online, real‐time measurement of many important chip properties on the
chip conveyor.

CMS measures chip mass flow, moisture, volume, dry bulk density and bark content. The measurement
system was developed by Centre de Recherche Industrielle du Québec (CRIQ).

CMS (Chip Management System) comprised of:
  • CMA (Chip Moisture Analyzer)
  • CWS (Chip Weighing System)
  • CSS (3D Chip Sizing System)
  • CVM (Chip Volumetric Measurement

The patented chip measurements and APC controls have been successfully commissioned at a Canadian Kraft pulp mill.
impregnation vessel and continuous hydraulic digester level s have been stabilized, liquor to wood ratio is controlled to target and Kappa number variability has been reduced.

The measurements allow flash steam use to be optimized in the pre‐steaming operation, while reducing venting to the atmosphere, allowing displaced fresh steam to be used in the mill’s turbine. This provides an extra electricity KW to be sold on the grid. The ultimate purpose is to control the digester blow line Kappa number and achieve stability in power production.

Mature, proven, reliable, CMS provides real time data & schematics. CMS is perfectly suited for Kraft digesters with chip sizing distribution index. Batch or Continuous, Kraft digester controls benefit from accurate measurement of moisture, mass flow, volume & dry bulk density.

TEXO’s COOK‐X advanced process controls (APC) use the measurements to manage chip filling, alkali to wood charging and stabilize digester cooking conditions. COOK-X delivers real time value.
