COCO - the CAPE-OPEN to CAPE-OPEN simulator

What is COCO?

COCO (CAPE-OPEN to CAPE-OPEN) is a free-of-charge CAPE-OPEN compliant steady-state simulation environment consisting of the following components:

	COFE - the CAPE-OPEN Flowsheet Environment is an intuitive graphical user interface to flow-sheeting. COFE has sequential solution algorithm using automatic tear streams. COFE displays properties of streams, deals with unit-conversion and provides plotting facilities.
	TEA - COCO's Thermodynamics for Engineering Applications, is based on the code of the thermodynamic library of ChemSep and includes a data bank of over 150 commonly used chemicals. The package exhibits more than 100 property calculation methods with their analytical or numerical derivatives.
	COUSCOUS - the CAPE-OPEN Unit-operations Simple package is shipped with COCO. It contains a splitter, a mixer, heat-exchangers, pumps and reactors amongst other unit operations. ChemSep-LITE, a limited version of ChemSep with a maximum of 10 components and 150 stages, can serve as an equilibrium distillation unit operation in COCO. A full version of the equilibrium and non-equilibrium column simulator can be obtained at http://www.chemsep.com/. ChemSep-LITE is included in the COCO installation.
	CORN - the CAPE-OPEN Reaction Numerics package that comes with COCO facilitates specifying any kind of kinetic or equilibrium reaction. Simple reactor units, like conversion reactors, CSTRs and plug flow reactors that can use the CORN package come with the COUSCOUS package.

System requirements: Windows XP or higher.

COFE is a graphical flowsheeting environment. All components (unit operations, thermodynamics and reactions) are imported from CAPE-OPEN models. Warnings and errors as well as additional information are logged to the output under each document window.

Streams in COFE: The stream dialog displays an arbitrary number of streams. Composition, temperature, pressure or phase fraction can be specified for each stream. Any input will automatically cause a flash calculation and an update of the properties. COCO also supplies unit conversion.

TEA is our CAPE-OPEN compliant thermodynamic property package. TEA is based on the thermodynamic library of ChemSep. The property data bank contains of over 150 commonly used chemicals. The package exhibits more than 100 property calculation routines with their analytical or numerical derivatives.

COUSCOUS is our CAPE-OPEN compliant set of unit operations. It includes simple basic unit operations for setting up a flowsheet, but also unit operations for testing and debugging purposes.

CORN is our CAPE-OPEN compliant reaction package; it makes it possible to specify a set of arbitrary reactions. A string parser facilitates entering expressions for reaction rates, equilibrium constants and heats of reaction.

CAPE-OPEN award 2006

COCO has been awarded the CO-LaN CAPE-OPEN award for the year 2006 for advances in CAPE-OPEN development. For a larger image of the award itself, click on the image below.
