DynAcid – Online concentration monitoring in pickling baths

Initial situation:

The targeted adjustment of the optimum concentrations of free acid fractions and metals in industrial steel pickling baths is of great importance for a consistently high product quality and plant productivity. With manual concentration monitoring, this is only possible to a limited extent because of the personnel and material expenditure. The BFI has developed online measuring technology “DynAcid®” for continuous concentration monitoring in pickling baths.

Objectives:

  • Continuous information on acid and metal salt concentration
  • Automated pickling bath control
  • Optimized pickling bath composition for a consistently high pickling result
  • Increase product quality and productivity
  • Saves time and cost-intensive chemical analysis

Solution:

  • Determination of concentration on the basis of a physico-mathematical model
  • Robust, expandable measurement solution
  • Available for HCl and H2SO4 pickling solutions and as prototype for acid mixtures HNO3 HF metals, HCl-Fe2 + -Fe3 +
  • Innovative process control of pickling lines, automated acid dosing

Our portfolio:

  • Presentation of the applicability of the measuring system in operational tests
  • Adjustment of the calibration of the characteristic field to operational conditions
  • Support during planning and realization of the installation of the measuring system
  • Continuous service of the installed measuring system – e.g. half or quarterly
