Chemistry

Econotech provides detailed chemical characterization that enables pulp and paper mills to effectively monitor, troubleshoot and improve their process and product.

Chemical properties are foundational, so understanding key chemistries at the right time and place gives engineers better control over the performance of their operation:

  • Track long-term trends at primary control points
  • Incorporate pre/post metrics into improvement projects
  • Take a data-driven approach to resolving upset conditions
