ESIG Vapour Pressure Tool
ESIG has developed a calculation tool that will help to determine whether hydrocarbon solvents are VOCs as defined by the EU Solvent Emissions Directive (or VOC Directive). This tool is meant to facilitate the often complex task of establishing vapour pressures of hydrocarbon solvents of low volatility.
The members of the Hydrocarbon Solvents Producers Association (HSPA) have adopted this tool as an industry standard to establish the VOC status of hydrocarbon solvents as outlined in the Solvent Emissions Directive (EU Directive 1999/13/EC). This Directive limits emissions of volatile organic compounds in many industries but does not specify any reference method to determine the vapour pressure of these substances.
The tool calculates the vapour pressure at 20°C and is applicable to hydrocarbon solvents with an initial boiling point above 200°C. The calculation method is based on a simple set of physico-chemical data (distillation range and aromatic content of the hydrocarbon product) and has been validated with experimental data. As well as solvent suppliers, the tool can also be utilised by solvent users such as coatings, adhesives and printing inks formulators.
