Need some help setting up a distillation column with steam stripping

[ygoprowonder]

Hi yall, I'm a newbie to chemical process simulation and have minimal chemical engineering experience, can you guys help me to set up a distillation column with steam stripping? I have a solution with sodium, water, and ammonia at around what should be a ph of 11. I have the temp set to around 50C, so I'm trying to get the steam to strip out the ammonia as a vapor and leave the sodium and water as a liquid, which will flow out out of the reboiler. I disabled the condenser because I want the ammonia to stay in vapor form. I put in my estimations, and I have the solution flowing into the middle stage, with the steam coming in from the bottom stage. The ammonia and steam should flow out of the top stage and the remaining water and sodium should flow out of the reboiler. I have 7 stages, which include the reboiler and condenser. Let me know if you need more info about the setup, or if you think i did something wrong or i input wrong estimations. When i try to solve it, it gives me the error "A convergence error was found while trying to solve the column. Possible reasons are: unfeasible specs, initial estimates far from solution and/or very non-ideal (wide-boiling or azeotropic) mixtures being fed to the column."

Something is wrong; surely you don't mean Sodium in water! Even in High School I saw Na react with water, H2O. So, I expect you mean NaCl or some such. And you are trying to strip ammonia out of the mixture. In most cases you don't have to do anything. Ammonia nqturally abandons Salt Water specially at temperature like 50 °C.
