Integrated modelling framework optimizes chemical process sustainability by balancing economic and environmental factors.

Why It Matters

In industrial design and engineering, achieving true sustainability requires a holistic approach that goes beyond simple compliance. This research highlights the importance of integrated tools that can quantify and compare the environmental and economic consequences of design choices throughout a process's lifecycle.

Key Finding

A structured approach using mathematical models and simulations can help designers make better decisions for chemical processes by balancing economic benefits with environmental impact.

Key Findings

• A consistent framework for decision support towards sustainable alternatives can be developed.
• Mathematical modeling and process simulation are effective tools for representing reality in process design.
• A multi-objective problem-solving strategy can identify the best compromise solution for sustainability.
• The framework is applicable across different industrial scenarios.

Research Evidence

Aim: To develop and validate a consistent framework for decision-making that supports sustainable alternatives in the design, upgrade, and operation of chemical processes, considering economic and environmental criteria.

Method: Mathematical modelling and process simulation

Procedure: A four-step procedure was developed, mirroring existing methods, and integrated with a set of mathematical modeling tools. This framework was applied to various industrial case studies to demonstrate its application in different scenarios, solving multi-objective problems using a compromise solution strategy.

Context: Chemical process design and operation

Design Principle

Integrate quantitative analysis of economic and environmental factors throughout the design and operational lifecycle of industrial processes to achieve optimal sustainability.

How to Apply

When designing or redesigning industrial processes, use simulation software and mathematical models to assess the environmental footprint (e.g., waste generation, energy consumption) and economic costs of different design options, aiming for a balance that meets sustainability targets.

Limitations

The effectiveness of the framework is dependent on the accuracy of the mathematical models and the availability of reliable data for simulation.
