Matlab CAPE-OPEN Unit Operation

The Matlab CAPE-OPEN Unit Operation is a unit operation implementation for which the calculations can be entered in Matlab.

To get started with the Matlab CAPE-OPEN unit operation, start your CAPE-OPEN capable simulation environment. Insert a Matlab CAPE-OPEN unit operation. Edit a unit operation. Define feed and product ports. Go back to the simulation environment and connect streams to the ports.

Now edit the unit operation again. On the Matlab tab, you can enter the Matlab calculation script. This script can obtain feed properties using the getFeedProp function. It can then do calculations, using thermo-dynamic calculations that are based on the underlying thermodynamic system of the simulation environment the unit operation is running in. It must specify all the product streams using setProduct, that takes composition and flow as well as two other properties required to specify the thermodynamic phase equilibrium.

A very simple example script would look like:

f1=getFeedProp(1,'flow')
f2=getFeedProp(2,'flow')
h1=getFeedProp(1,'enthalpy')
h2=getFeedProp(2,'enthalpy')
p1=getFeedProp(1,'pressure')
p2=getFeedProp(2,'pressure')
p=min(p1,p2)
f=f1+f2
h=(h1*f1+h2*f2)/f
totF=sum(f)
setProduct(1,totF,f/totF,'pressure',p,'enthalpy',h)

Requirements

The Matab unit operation will function in CAPE-OPEN compliant simulation environments that support version 1.1 thermodynamics. It has been tested in the COCO simulator.

Matlab version 5.3 (32-bits) or higher, or Matlab version 7.1 (64-bits) or higher must be installed and running at your system. The Matlab CAPE-OPEN unit operation has been tested with Matlab versions 5.3, 6.1, 7.7, 7.8, 7.9, 7.10, 7.11, 7.12, 7.13, 7.14, 8.0, 8.1 and 8.2.
