the hydrate model in version 1.2c is really very accurate

[mrbabu]

can you give an estimate of possible errors when calculating hydrate formation conditions with Prode Properties including 20/30 % methanol ?
Thanks

there are a few values published by developer,

[link Point to another website Only the registered members can access]
I have verified some of these points (ask Prode for the list),
with simplified model for hydrate formation pressure you may expect an error in the range 3-15% (depending from structure and temperature),
errors in hydrate formation temperature are in the range 1-2 K

the complex model is more accurate,

when adding methanol as inhibitor erros are about the same (with the specific parameters provided for CPA PR Cubic Plus Association or other models,
however I suggest to contact Prode for more accurate figures...

can someone provide me a link for the download of those awesome shared files?
its keep redirecting me....
newbie in the forum although

[carlo.stenali]

this is the page to download Prode Properties
'http://www.prode.com/en/download.htm'
select ppp.exe and take note of password (read the page for the password)
to install follow the instructions in that page,

can you share comments about the dynamic column model available in Prode Properties Extended ?
I understand that it allows to simulate transients keeping in account liquid and vapor hold-ups in all plates (rigorous model).

[hans23]

correct*
the main difference (against steady-state model) is that it keeps in account vapor & liquid holdups*
you can solve many different problems*
I can add that solver is robust (compared to different software) and reasonably fast*
do you have specific questions ?

[mderra]

Almart*
with dynamic column in Prode* it is possible to model rigorously even **BATCH COLUMNS**

the solver is very good as reported by Hans23

[asanter]

have you tested Prode Properties hydrate models with salts ?
I am considering to install the electrolyte model and wish to receive comments.
