I am having some difficulties in simulating a distillation column for dehydration of natural gas.  My values doesn't converge despite multiple trials. 

 

I have look through a number of resources like YouTube channels but it doesn't help much.

 

 

Additional information that for this simulation:

 

The feed enters on 4th stage.

Total stage : 10

Condenser pressure = 102kPa

Reboiler pressure = 120kPa

Reboiler temperature = 200

Full reflux with ratio of 0.01

 

Thank you

Dear Mashii,

I checked your simulation model of TEG dehydration unit.

it is required to do the following:-

- Reduce No of trays in TEG contactor to only 3 trays. 

- Reduce No of trays in Regeneration column to only one tray and the rich TEG enters it.

- Increase the TEG flow rate to 7500 gpm instead of 2005.
