Process Optimization

Optimization Goal

The goal is to develop a suitable temperature program for optimum product quality without trial and error. The results of the optimization can be achieved for:

  • A given measurement output,
  • A constant rate of output signal like RCM or RCS,
  • A given conversion, partial mass and partial area,
  • A constant conversion rate.

This feature allows for the simulation of data once the experimental data is described by model-free or model-based kinetics. The temperature profile can be calculated and optimized taking into account defined boundary conditions; e.g., constant conversion rate, constant signal rate, temperature range and range of heating rates.

The results depend on the chosen model-free or model-based method and its parameters. Careful kinetic analysis of the experimental data is required prior to calculating the optimization (see column at right).

Optimization Types

  • Conversion rate
  • Signal rate (RCM for thermogravimetry and RCS for dilatometry) 
Calculated temperature program for conversion rate of 1%/min for TGA decomposition of LaOH3.
Concentrations for RCM program of 1%/min. Maximum of concentration for intermediate product is at 10 min.
