What kind of properties package you use?

[@beenishhanif1040]

what to do if i am getting -'fatal error zero diagonal in column matrix'?

[@akshaybankar1880]

Hi i am also getting same error. unable to solve. pls reply me

[@akshaybankar1880]

5. Some of the coefficients are not specified, since some of the tabs are left blank. There are a number of ways to fix this. First the coefficients can either be looked up or experimentally determined, and then entered straight into the appropriate box. Or, HYSYS can estimate the unknown coefficients using equilibrium relationships. To do that select either “UNIFAC VLE” or “UNIFAC LLE” and then clicking on the tab “Unknowns Only”. In Liquid-Liquid Extraction processes, UNIFAC LLE is the appropriate estimation to use. Close the Binary Coefficient window, and enter the simulation environment.

what does it mean if I get the error: "zero flow calculated on stage 1_main tower"?

[@icedmocha5264]

nvm I figured it out. the problem was the fluid package used

[@collinsmordi8721]

Ok

[@easierchemistry9676]

@@collinsmordi8721 How do you change the fluid package in the extractor? I have the same issue as "iced mocha" but I do not know how to resolve it.

[@oshinugatobi8921]

How did u do it

[@HawakaMethod]

Is liq-liq extractor same as the extractive distillation?

[@tekkiminside4197]

totally different
