Program for Assisting the
Replacement of Industrial Solvents
PARIS II is a software tool that can design less hazardous solvents without
compromising solvent performance. Thanks to its advanced technology and extensive knowledge base, PARIS II makes it easy to design new solvents and identify "green" replacements for solvents currently in use - in hours rather then weeks. Since PARIS II includes chemical data and estimation methods, the user needs to know only the composition of the solvent to be replaced in order to run the program.
PARIS II identifies the composition of a replacement for MEK.
|With PARIS II you can:
- design new solvents for single chemicals or mixtures
- evaluate solvents for their impact on the air and the environment
- evaluate solvents for toxicity, health and safety effects
- match new solvents to existing chemical processes
- get a ranked list of solvent replacements quickly and easily
PARIS II is unique for its ability to design mixtures when no single compound
can meet user specifications. It brings together a set of unique algorithms
developed under the leadership of Dr. Heriberto Cabezas of the National Risk
Management Research Laboratory, USEPA, Cincinnati Ohio.
A number of important databases are included in PARIS II:
|DIPPR Database ||physical, transport and thermodynamic properties for over 1685 industrial chemicals from the American Institute of Chemical Engineers|
|UNIFAC ||programs and over 4000 parameters covering almost all chemical families. This method, developed at the Universitry of Denmark, is used for predicting solubility (activity coefficients) and the chemical properties of mixtures|
|Eight categories of environmental impact and health & safety data from the EPA and other sources ||Included are global warming, acid rain, ozone depletion, smog formation , human toxicity (via inhalation/dermal exposure and ingestion), toxicity to aquatic life and terrestrial animals
PARIS II helps to reduce the undesirable effects of chemicals on the workplace and the environment. Chemists research engineers, process engineers, materials scientists, industrial hygienists and other professionals concerned about the impact of industrial solvents will benefit from this powerful tool.
PARIS II is available from Technical Database Services(TDS). Please
