Formulation assistance

• Replacing solvents, reagents or additives with other products of equivalent or better capabilities

• Identifying products for their specific physical properties

Process modelling

• Selection of pertinent data

• Implementation of appropriate models

• Adjusting parameters based on experimental data (laboratory, pilot plant or production unit measurements)

• Validation of the models in process conditions

• Integration/validation of the models in/with process simulators

Screening of new molecules

• Implementation of a knowledge model combining sought-after physical properties and molecular descriptors.

• Specific prediction of the desired properties.

• Selection of candidates for experimental testing.

The original approach by PROCESSIUM combines screening of databases and new molecules generation:

• Systematic search

• Optimization tools

• Knowledge build-up

• Implementation of specific knowledge models:

      - Sought-after physical properties

      - Most adapted molecular structures

      - Integration of available experimental informations
