Is there a freeware or open source program for chemical engineers to design and simulate a Plant design?  An example of the type of software is Aspen 12.1 and ProII but I am pretty sure I can not afford these.

Hello pollution,

I personally have a program which I created (It took over 8 years to create), and I know of zero freeware/open source programs. 

Most people guard this info/data very well.

I wish you the best,

AFAIK There isen't any..

The best thing you could do would be to write one youself... Probably using Octave as a starting point...

You may wa nt to see Sim42, which was created as an Open source simulations/w. But now it is not active.

I was reading about OPENCheESE here... and I'm sorry about it's stopped.

Resuscitating the topic... 
I know about 2 opensource process simulators:

• ASCEND
• DWSim

List of free process simulators:

• ChemSep
• COCO
• EMSO

and a copy of sim42 (dead free process simulator) is available here.

- [NEW] Inside-Out Three-Phase (VLLE) Flash Algorithm
- [NEW] PC-SAFT (without association term) Property Package
- [NEW] UNIFAC Property Package with Liquid-Liquid interaction parameters
- [NEW] Liquid-Liquid Extractor operation mode for the Absorption Column
- [NEW] Three-Phase separation mode for the Vessel
- [NEW] ChemSep database automatic loading (Windows only)
- [NEW] Watch window - allows property monitoring from different objects at the same time
- [NEW] CAPE-OPEN Unit Reports window - view output from CAPE-OPEN Unit Operations (Windows only)
- [NEW] Updated flowsheet drawing theme
- [NEW] 'Send Error Info' button added to the Unhandled Exception window (Windows only)
