INTRODUCTION TO COCO:

• Simulation environment (COFE)
• Thermodynamic property package (TEA)
• Collection of unit operations (COUSCOUS)
• Reaction package (CORN)

TEA: THERMODYNAMICS FOR

ENGINEERING APPLICATIONS

• Pure compound data library (extendible, or use DIPPR)
• 100+ Property calculation methods (25+ different properties)
• Property derivatives
• Support of external property calculation routines and external equilibrium servers

TEA: THERMODYNAMICS FOR

ENGINEERING APPLICATIONS

VLE equilibrium calculations

• Large diversity of supported flash specifications
• Inside-out approach
• Post-checking of solution
• Back-up full Newton approach

• Using ChemSep in COFE
• Advanced flowsheeting features

WHAT IS CAPE-OPEN?

CAPE: Computer Applications in Production and Engineering (source: about.com) Computer-Aided Process Engineering (source: CO-LaN leaflet) OPEN: Freely available standard specification

WHAT IS CAPE-OPEN?

It is described in a formal documentation set covering areas such as unit operations, physical properties and numerical solvers, (…). In practice, it enables components supplied by third parties, such as niche physical property packages or unit operation models, to be used in “plug and play” mode in commercial process modelling software tools. (Note: practical implementations limited to physical property packages and unit operations)

WHAT IS CAPE-OPEN?

In reality this currently means:

• physical property package implementations
• unit operation implementations
• support for both of these in major simulation engines
• restricted to COM on Windows

GOOD REASONS FOR GOING CAPE-

OPEN:

• Wide support for process models in simulation engines
• Write your software once, run in multiple environments
• Validate your models by exchanging parts of your models with those of different vendors
