Physical Properties of Fluids

The Physical Property Data Service (PPDS) is a software suite used extensively in the chemical production, oil & gas, pharmaceutical, fine chemical, power generation and process industries.

PPDS enables users to undertake complex calculations and simulations across a wide range of process and engineering applications. The software was designed, developed and is maintained by NEL staff.

If you are interested in taking advantage of our FREE 30-day TRIAL of PPDS, please contact us.

PPDS provides users with quality assured, peer reviewed and fully traceable data which can be used through all stages of the process lifecycle from design and operation to maintenance and decommissioning.

PPDS is a core software product which is also used as part of NEL’s physical properties of fluid consultancy package.

PPDS key applications:

Specification and sizing of equipment
Separation calculations
Heat transfer and fluid flow
Evaluation of phase envelopes
Establishment of safety critical data
Property prediction for speciality chemicals
Fluid properties calculation

PPDS includes physical properties of fluid information on more than 1,500 chemicals, constant and variable physical properties, thermodynamic model sets and flash calculations. The software and databases have been accredited to BS EN ISO 9001.

Special packages are available for petroleum fractions, aqueous solutions and refrigerants.

There are various licence types to suit user needs. If you are interested in taking advantage of our free 30-day trial of PPDS, please contact us.

PPDS has been designed with an extensive tabular and graphical display, handles a wide choice of units and can be utilised both as a stand-alone or fully networked application. Using industry standard software, users can develop their own templates. PPDS can also link to other industry standard databases, file generators and process simulators.
