gPROMS ProcessBuilder

Environment & features

ProcessBuilder supports all the "core" flowsheeting functionality familiar to users from generations of traditional flowsheeting simulators.

You construct flowsheets by dragging & dropping unit models from a model palette, connecting them via streams and specifying required values, and then perform steady-state and dynamic simulation.

The difference with ProcessBuilder is that you can also perform steady-state and dynamic optimisation, as well as many advanced applications not available via traditional simulators.

Environment

The user environment is a standard drag & drop flowsheeting environment that will be familiar to users of traditional process simulation packages:

gPROMS ProcessBuilder

However, because ProcessBuilder is built on PSE's powerful gPROMS platform, it has access to all gPROMS' advanced process modellng features too. It thus provides:

  • a graphical flowsheeting environment for process engineers
  • an advanced custom modelling environment for expert modellers creating new models or managing model libraries
  • an execution-only environment for non-modellers such as operations personnel.

Features & advantages

ProcessBuilder is a feature-rich process modelling and simulation environment:

ProcessBuilder environment

  • Drag-and-drop flowsheeting, with intelligent line routing and clearly-differentiated stream types for rapid model construction
  • Integrated steady-state and dynamic modelling and solution capabilities
  • Palette view to access libraries of models
  • Project tree environment for easy access of all elements
  • tab-based context-specific forms for entering equipment specification data
  • Powerful custom modelling capabilities for creating models specific to your processes, or capturing your IP
  • Comprehensive results visualisation: stream variables, tables, 2-D and 3-D plots …

Model libraries

  • State-of-the-art steady-state and dynamic process models for all common process equipment
  • Equipment not commonly found in process simulators: kinetic reactors (various), adsorption, membranes …
  • gPROMS Advanced Model Libraries for Fixed-bed Catalytic Reactors (AML:FBCR), Fischer-Tropsch Reactors (AML:FBCR FT), Bubble Column Reactors (AML:BCR) and Trickle Bed Reactors(AML:TBR), the world's leading reactor models
  • gPROMS Advanced Model Library for Gas-Liquid Contactors (AML:GLC) for rate-based modelling of any type of separation equipment

Physical properties

  • KBC Multiflash rigorous multi-component physical properties plus binary interaction parameters
  • DIPPR database (2000+ components)
  • State-of-the-art gSAFT advanced thermodynamics: SAFT-VR and SAFT-γ Mie (group contribution) for strongly-associating fluids
  • Other property options, depending on requirements

Optimisation

  • State-state optimisation capable of handling many decision variables simultaneously
  • State-of-the-art dynamic optimisation, for – for example – optimising batch recipes or feed or product grade change trajectories
  • Mixed-integer optimisation for discrete decisions, such as number of stages in a distillation column, or process routing decisions for flowsheet synthesis

gPROMS platform features

  • Industry-leading model validation capabilities for estimating model parameters from laboratory, pilot plant or operational data
  • Comprehensive Quality Assurance tools, including project comparison and creation of time-stamped Cases
  • Library management tools for creating model libraries and making them accessible across the organisation
  • Model export tools for exporting ProcessBuilder flowsheets to execute within other environments such as CAPE-OPEN steady-state flowsheeting simulators (e.g. Aspen Technology's Aspen Plus® and Hysys® and Invensys's PRO/II®), The MathWorks Inc.'s MATLAB® environment, Microsoft Excel or custom interfaces (e.g. Visual Basic for Applications)

Solution

  • Multiple activities using the same model: steady-state and dynamic simulation, parameter estimation, steady-state and dynamic optimisation
  • Modelling and solution power specially designed to handle the simultaneous solution of the large number of equations (often hundreds of thousands and sometimes millions) that can result from such modelling.
  • Proprietary Model Initialisation Procedures for ensuring robust solution without user-provided initial guesses, even in cases of multiple interacting recycles of mass and energy
  • Multiple supported platforms, including Linux and Microsoft Windows 64-bit versions.
