The major benefits to be had from process modeling are improved understanding of the circuit
concerned and reduced technical risk.
For conceptual circuits, the benefits include the following.
- Calculation of indicative reagent/utility/energy consumptions.
- Calculation of indicative product/residue/effluent quantities.
- Quantitative ranking of potentially applicable circuits.
- Early definition of critical assumptions and/or exposure of “fatal flaws”.
For circuits under development, the benefits include the following.
- Substantially more cost effective laboratory and pilot-scale development work.
- Much earlier detection of technically/economically flawed concepts, enabling the project concerned to be modified or rationally discarded and the resources deployed elsewhere without the waste of substantial amounts of time and money.
- Better engineering feasibility studies from better mass/energy balances.
For existing operations, the benefits include the following.
- Optimization of the circuit.
- More effective training of operating and technical staff.
- Evaluation of changes to operating parameters substantially reduces the risk of such changes being ineffective or adversely affecting the financial/environmental performance of the circuit.
- Evaluation of the effect of feed composition on the financial and environmental performance of the circuit substantially reduces the risk of processing unsuitable feed.
- Quantifying the impact of envisaged changes to the circuit on its financial/environmental performance substantially reduces the risk of ineffective or detrimental changes to the process equipment.
