Two- and three-phase fluid flow in pipelines,
heat transfer, long transmission pipelines
compressible fluids, property profiles,
pressure relief

Whenever the fluid in a pipeline...

• Is compressible (gases, vapors, liquids at high pressure, supercritical fluids)
• Is complex oil or chemical mixture
• Is a mixture of vapor-liquid or liquid-solid or vapor-liquid-solid (two- or three-phase flow)

...you need a thermophysical property package to determine physical properties of media flowing through the piping.

Whenever there is significant heat transfer between the pipe contents and the ambient (air, water, soil, seawater or any other environment), the heat transfer affects both properties of fluid along the pipe and  the pressure drop. In long transmission pipelines, properties of fluid continually change (especially for compressible fluids) and it affects pressure drop over the pipeline. Simple model assuming constant physical properties cannot be applied in such case. Piping systems also need pressure relief calculations, tanks

For all aforementioned purposes, CHEMCAD or CC-DYNAMICS (and its sub-part CC-SAFETY NET) are the answer. CHEMCAD and CC-DYNAMICS (and CC-SAFETY NET) include:

• State-of-art DIPPR databank of physical properties for over 2000 substances
• Crude oil databank with 250 crude oils
• Distillation curves to determine the properties of oil and oil products based on laboratory data
• Calculation of physical properties for mixtures, single-, two- and three-phase
• Over 40 vapor-liquid-solid methods for thermodynamics
• DECHEMA databank of Binary Interaction Parameters for non-ideal mixtures
• User added components including prediction of properties for less common substances
• Compressible and non-compressible fluids, Joule-Thompson effect
• Detailed pressure drop models for single-, two- and three-phase flow including slurry flow. Nor-Par additionally delivers to its clients a library of 5 most modern two-phase flow models. The two-phase flow models include slug flow prediction.
• Detailed heat transfer model between the pipe contents and the ambient (air, water, soil, custom) including up to 10 different insulation layers
• Segmented calculation for long transmission pipelines
• Property profiles along the pipeline
• Piping network capability
• Flaring networks
• Sizing and rating of Pressure Relief Valves and Rupture/Burst Disks according to DIERS technology
• Tanks (in CC-DYNAMICS)
• Sizing of control valves and orifices
