Applies To Product(s): PlantFLOW Version(s): All Environment: N/A Area: Licensing Subarea: Original Author: Bentley Technical Support Group Problem: What is the difference of PlantFLOW vs. PlantFLOW Plus Answer: 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 Library Uses user defined temperature dependent properties in PLANTLIQ.PFL. Predefined properties include water, mercury, R-12 and ammonia. Gas Library 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 Gas 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) See Also Bentley AutoPIPE External Links Bentley Technical Support KnowledgeBase Bentley LEARN Server Comments or Corrections?
