The software tool to find greener solvent replacements, PARIS III.

Area of Science:

• Environmental Science
• Chemical Engineering
• Green Chemistry

Background:

• Industrial solvents pose significant environmental risks.
• Replacing hazardous solvents with safer alternatives is crucial for pollution prevention.
• Existing methods for solvent substitution can be limited in scope and efficiency.

Purpose of the Study:

• To introduce PARIS III (Program for Assisting the Replacement of Industrial Solvents III), a software tool for identifying environmentally benign solvent mixtures.
• To enable industries to find greener solvent substitutes that maintain or improve performance compared to traditional industrial solvents.
• To facilitate the selection of optimal solvent replacements based on environmental impact and performance criteria.

Main Methods:

• Utilizing a comprehensive database of solvent properties to search through millions of possible combinations.
• Implementing a systematic approach to identify solvent mixtures with comparable performance to the original solvents.
• Incorporating adjustable weighting factors for environmental impact and property matching to tailor searches to specific regional concerns and requirements.

Main Results:

• Identification of numerous solvent mixtures that can replace conventional industrial solvents.
• Demonstration of the software's capability to find substitutes with reduced environmental impact.
• Validation of the method's effectiveness in discovering greener alternatives through extensive computational searches.

Conclusions:

• PARIS III is an effective tool for pollution prevention through solvent substitution.
• The software facilitates the discovery of high-performing, environmentally conscious solvent alternatives.
• This approach supports industries in transitioning to more sustainable chemical practices.
