hydrate inhibition, glycol (MEG) and salts with Prode software
hydrate inhibition, glycol (MEG) and salts with Prode software
(OP)
we inject glycol as hydrate inhibitor in a natural gas stream which contains water + some salts (mainly Nacl), glycol dosage has been estimated averaging depression temperatures of MEG & salts (GPA), I have now Prode software, do you have expericence with CPA electrolyte or Pitzer models ? Can you recommend one for this (MEG+salts) application ?

you may find some numbers here,
"http://www.prode.com/en/hydrate.htm"
with a different method (manual) you sum up depression temperatures due to different inhibitors...

the values calculated with MEG are close to GPA report but I have not experience including salts, ok, CPA electrolyte looks more suitable than Pitzer for this application.
