Re: Heterogeneous Reaction PFR Bug
Apologies for the very late response. Thanks for the answer, I've also found and fixed the faulty rate equation.

Heterogeneous Reaction PFR Bug
Hi all, I'm encountering a persistent problem in the simulation of heterogeneous reaction in PFR. The simulation file is attached. Similar to that in a previous thread , I put max(0,X("component name")) to avoid the value in question from getting below zero. Instead, the simulation gives e...

Re: Adding energy stream to customized unit (Matlab CAPE-OPE
The Matlab CAPE-OPEN Unit Operation does not currently support energy streams. Are you planning on doing this in COCO/COFE? If not, which simulator will you use? Yes, I'll be planning to do it in COCO. If it doesn't support energy stream, is it possible to express the energy consumption of the unit...

Adding energy stream to customized unit (Matlab CAPE-OPEN)
Hello, I have been tinkering an idea of adding an energy stream to the customized separator unit in the COCO-Matlab CAPE-OPEN's Water-Ethanol membrane distillation model tutorial (illustration is given in figure below. The problem is that I checked out the manual of CAPE-OPEN and it doesn't include ...

Re: Problem in simulating Heterogeneous Reactor
Re-checking your expression, it does go to zero in case X[nitric oxide] goes to zero - it is the only term in the numerator. The negative rate of nitric oxide however is within integration tolerance. Perhaps try the solution with max(0, ... ) to avoid the negative value. Thank you for the reply, Ja...

Problem in simulating Heterogeneous Reactor
Hi all, I'm currently facing a problem in simulating heterogeneous reactor with user-defined reaction kinetic expression. The reactor converts NO, CO, and H2O into NH3 and N2, hence it has two reactions (namely NTA_NH3 and NTA_N2, respectively). My intention is to parametrize the dimension and inlet...
