Lucie

LUCIE is an Advanced Process Control application commissioned by Lafarge, the largest producer of cement in the world, to control the cement production process at their plants.

LUCIE embodies the following practices into the Gensym G2™ knowledgebase:

  • Establishes a common operating philosophy which could be improved/edited by non-programmers
  • Mimics knowledge base of operators’ expertise 
  • Develops a generic tool easily transportable and deployed to any plant

Using the design principles above, the following process are controlled by the application:

  • Kiln (long dry, preheater, precalciner, Lepol)
  • Cooler (except planetary coolers)
  • Ball Mills
  • Vertical Mills
  • Fuel Manager

Performance Improvement through Lucie

  • Production increase by stabilizing the process
  • Decrease of specific power consumption
  • Increase of product uniformity by minimizing the quality fluctuations
  • Master complex fuel mixtures by the fuel manager
  • Relieve operators and allows time for other tasks
