Research and Development: Physical Properties of Fluids

Physical properties of Fluids
TUV NEL has an extensive track record in the area of physical properties of fluids, ranging from fundamental research into specific fluid properties, to the provision of such data via an industry standard software package called PPDS (physical properties data service).

Traceable Database
PPDS is used to simulate and model many chemical combinations to look at suitability of materials, equipment and processes. By using the fully traceable database of 1500 chemicals, the software can input into many aspects of product design and development, and the software package can be integrated into bespoke company systems.

Theoretical and Practical
The combination of the traceable database, industry-standard calculation procedures and an expert assessment system provides quality codes for output data. This gives users a complete audit trail compared to the use of in-house or black-box software approaches. Our Density Standards facilities enable the density of liquids and gases to be measured very accurately across an extended temperature and pressure range.

Densitometers
Recent work has included the characterisation of fluids for use in the calibration of the densitometers used throughout the North Sea oil industry. We have also carried out traceable calibration of densitometers to national standards and also for research in complex fluids such as live crude oils and biofuels.
