Trying to make a RCM of toluene/water/methanol in Chemsep using EOS P-SRK:
windows (10) error message:

gf-cres.exe has stopped working

shows up for each curve

Next problem:

A parametric study on the pr as input and p-c1 as output crashes CoFe agin

Not any other value though, 600 works! then to 900 crash
E.

attached flowsheet crashes COFE when changing the set-point of controller TC-1 to 900 (and any other value)

plz resolve,

Thanks E.

Thanks for the fix,

I wouldn't call air at ambient conditions supercritical though; it is above the critical critcal T of -140C but well below critical p of 38 bar thus still a gas.

PR says air at amb conditions is a liquid!, SRK is ok:
.21 mol% o2
.79 N2
1 bar
20 C

Edwin

Youre supercritical!

Mirroring a mixer icon horizontally, Ctrl+M, crashes COFE.

I haven't tried all other icons or vert mirror or rotations, but the ones i tried also crashed COFE

Hi,

When calculating the temperature difference, measured by "measure units" in the inlet and outlet of a heat exchanger:

Hot (h) equals 140C, Cold (c) 40.2C and the result from the calculator, h-c is -173C!

see attached fsd

Hi, on first solve the attached flowsheet gives an error message "failed to solve gibbsreactor1" the second solve gives another message "dimensionality mismatch" and after OK'ing COFE crashes. https://drive.google.com/file/d/0ByJod0fkM7DCRlZiYnpLYXZfYmM/edit?usp=sharing the file ...
