Ammonia Plant Simulation

My first major job in a Ammonia Urea complex was to prepare a complete plant simulation program starting from natural gas feed to final product using Excel's Visual basic interface.

It took me 60 complete mandays of working for which I thank my BOSS Mr. Pankaj Shah who spared me totally from other day to day jobs for the preparation of this package.

In the first part it uses complete kinetic models of Primary & secondary reformer based on inlet temperature & catalyst volume & predicts outlet composition of reformed gas including heat load for primary reformer. Then comes steam generation in WHB downstream of SR. Next part includes shift reactor models with all waste heat recovery. I have skipped CO2 removal section modelling as it required absorption mass transfer etc. So it considers CO2 in the clean gas at absorber outlet. Methanator model includes only temp calculation as CO & CO2 are generally in ppm level.

Second part includes complete ammonia synthesis loop using generalized correlation of EOS and other solubility data derived from a book by Slack which is very popular in Fertilizer industry.

This package is capable of following
  1. Simulation of entire ammonia plant
  2. Can be used for predicting changes in operating parameters based on change in certain consitions e.g. Feed, Temp, Pressure etc.
  3. Can be used for Optimizing process parameters based on considered objective
  4. Can predict performance of equipments
  5. Can predict errors in measurements
  6. Can predict problem in particular equipment / process part
  7. Can be used for evaluation of modification schemes
The package is flexible in making changes in the process as it was developed in Excel. It is having 19 Excel sheets in one file with ~25 routines & takes ~2-3 Hrs
of computing.

The result of this package were matching with the evaluations of Technology Supplier Haldor Tosoe.

So if anyone requires simulation of ammonia plant I can do it.

Dear Sir,
I have to simulate Primary Reformer in Ammonia Plant (for a 1520 MTPD Topsoe plant) for my final year project. Feedstock to be NG. I searched in internet for various softwares/articles, but to no avail. I learnt about REF-SYS and Petrosim but dont have availability of such softs. I know it's really a painful job to simulate whole Ammonia plant, and i appreciate your work. Can you spare some time to give me some idea or referances how to simulate reformer. If possible kindly provide me the spreadsheet. If not then plz guide me how to start the same. With regards

Hi, i will truly appreciate it if i can get a copy of your excel file for ammonia plants simulation. i am currently working on one but it has no kinetic calculations in it, so it always end up with about a 10-15% error in my calculation. I would like a copy of yours pls.

Dear Hardik
This is not a free software & was made for Ammonia plants.

Thanks

kindly provide me the excel file for ammonia simulation, i am currently i m carrying my graduation project of ammonia plant modeling n simulation. i m in a middle of no where due to the complexity and unavailbility of the simulation data.

profmaster said...

Dear Wazien
As I mentioned earlier it is not free, its very valuable & have a cost of ~15000-20000$ right now.

So I can not share it but can help u if required.
