Problem:
What is the difference of PlantFLOW vs. PlantFLOW Plus
Solution:
From the online help:
The following table shows the differences between PlantFLOW and PlantFLOW plus
| Feature | PlantFLOW Standard | PlantFLOW PLUS |
| Liquids | Yes | Yes |
| Ideal Gas | Yes | Yes |
| Non-Ideal Gas | No | Yes |
| Heat transfer | No | Yes |
| Nist Hydrocarbon Liquid Gas Mixture | No | Yes |
| ASME Steam | No | Yes |
| Geometry point or Solver (max node limit) | 1000 | 10,000 |
Fluid Types- PlantFLOW Standard Version
| AGA-8 Gas | AGA-8 Equation of state for natural gas mixtures. It includes 20 different components. PlantFLOW standard sets the gas compressibility factor (Z) to one (Ideal Gas). |
|
Liquid |
Uses user defined temperature dependent properties in PLANTLIQ.PFL. Predefined properties include water, mercury, R-12 and ammonia. |
|
Gas |
Uses user defined gas components in PLANTGAS.PFL. Peng-Robinson equation of state is used to compute gas mixture properties. PlantFLOW standard sets the gas compressibility factor (Z) to one (Ideal Gas). |
|
Pseudo | User defined gas properties. Heat transfer not possible with this fluid type. |
| Liquid | User defined liquid properties. Heat transfer not possible with this fluid type. |
Extra Fluids Available in PlantFLOW Plus
| ASME Steam | Superheated steam based ASME steam tables, sixth edition (1997), based on IFC 1967 |
| NIST Gas | Hydrocarbon gas mixtures based on National Institute of Standards and Technology, database 4 (SUPERTRAPP) |
| NIST Liquid | Hydrocarbon liquid mixtures based on National Institute of Standards and Technology, database 4 (SUPERTRAPP) |
