Hello,

 

I would like your feedback on the following:

 

Would Aspen HYSYS/ ASPEN PLUS be helpful in identifying:

 

-MISCIBILITY

-COALESCENCE

-MASS /HEAT TRANSFER

-COAGULATION

-EMULSION

-FOAMING

-PARTITIONING

-CHELATION

 

And would appreciate directing me to some examples of such simulations using Aspen or other products.

 

Thanks a lot.

 

Bal.

My 2 cents.

 

-MISCIBILITY:  Yes, if you have the model interaction parameters or if these parameters are in the library. If not, can estimate by using Unifac.

 

-MASS /HEAT TRANSFER: Limited to some models (Heat exchangers, absorbers, piping)

 

-EMULSION: No

 

-FOAMING: No

 

-PARTITIONING: Yes, if you have the model interaction parameters.

bal,

in my opinion you should define the field of application , as said by Sami some properties can be estimated (for available fluids and applicable models) with most simulators (Aspen, Chemcad, Unisim, VMG, Prode etc.) while others could require specific applications

[Bal]

Thanks SamI and Serra:)

 

It's for oil and gas.. do you have any further thoughts?

[serra]

as said it depends from specific application,
in some cases a software can help (I use mainly Prode + Excel but I presume most simulators have equivalent features),

but it depends, some cases :

for liquid-liquid miscibility etc.  you solve phase equilibria

for coalescence probably you mean simulation of a coalescer, I have created (Excel) a specific model (don't know if Aspen has buil-in model)

for chelation you can define (for example) equilibrium cosntants in reaction

for coagulation (for example in water treatment) you solve a solid precipitation (multi phase equilibria)

for emulsions, foaming etc. better to define specific models (or applications),
