Please, excuse me, I forgot add a file.Here the FSD with water and edc.
Exists any other method in COFE how to obtain LL equilibrium as using UNIFAC LL aktivity model?

Ok, I try it. I made the same problem again. and i start with only EDC and water in equimolar composition. I use EoS UNIFAC VLE,chemsep internal thermodynamic: liquid liquid gama K value and UNIFAC activity coeff. Then I look beter on physical properties and watch an error in phase density: Light li...

and my flowsheet

Hello, everybody, Hello Jasper :) I solve LL equilibrium in 2 liquids flash. Beetwen H2O (cca1800 kg/h) and 1,2 EDC (8100 kg/h) (equimoar composition) does it go very well. Than I try add new component chloral (cca170 kg/h). Simulation was done, but with not realistic equilibrium, chloral went in ph...

Hi, Jasper.
It works very good.
Thank you for checking.

Thank you, Mr. Harry. In proces, water is not in use. Expectional with HCl due to corosion aspect. little amount (2-5ppm water) is real amount in feed but in simulation it doesnt matter. In columns with many trays (40 and more) water is cumulated. Its normal steady state. If I simulate HCL-VCM-EDC-H...

Dear colleaguess! I try simulate quench column. Here I have problem how to set mass flow of quench stream. This stream is join into hot steam of medium. Then it goes as low temperature steam feed into column. In older version I used flow constraint, but there were mass-ballance errors in some units....

thank. good idea, Mr jasper. Its pleasure to work with you! I like this program

thank you for navigating, column is solve nice! but the real problem its then probably else yet... its problem when the column is implemented into flowsheet, because, ever when top and bottom stream go in heat exchangers beetwen C201 and HCl removal column, flowsheet doesnt converge. to be right, pr...

Please, apologize me, only fault due quick work . Here is the right fsd.
