Reactive-transport support

Connect chemical reactions with transport.

Specialist support with conceptual model development, PHREEQC and PHAST workflows, parameter testing and the interpretation of coupled reactive systems.

The decision

What changes when reactions and transport interact?

Reaction and movement need to be considered together, a model is producing unexpected behaviour, or a team needs a specialist review of its modelling approach.

What the work can include

  • Clarify the model purpose, domain and conceptual assumptions.
  • Review how chemical reactions and transport are represented.
  • Support parameter testing and diagnosis of unexpected model behaviour.
  • Interpret outputs alongside field or experimental evidence.
  • Review the treatment of dissolution, precipitation and transport in mineral-carbonation studies; process engineering is outside this scientific remit.

Potential outputs

The exact deliverables are agreed in the scope. A package can include:

  • A conceptual-model and assumptions note.
  • An agreed set of sensitivity tests or scenario comparisons.
  • Documented modelling support and interpretation.
  • A handover discussion or technical mentoring session.

Clear scope. Useful output.

A defined question, agreed deliverables and a transparent account of assumptions make the work easier to use.
