ABOUT CHEMICAL PROCESS SIMULATION
Chemical Process Simulation is a model-based representation of chemical, physical, biological, and other technical processes and unit operations in software. Basic prerequisites are a thorough knowledge of chemical and physical properties of pure components and mixtures, of reactions, and of mathematical models which, in combination, allow the calculation of a process in a computing device.
Process simulation software describes processes in flow diagrams where unit operations are positioned and connected by product or educt streams. The software has to solve the mass and energy balance to find a stable operating point. The goal of a process simulation is to find optimal conditions for a process.
Process simulation uses models which introduce approximations and assumptions but allow the description of a property over a wide range of temperatures and pressures which might not be covered by real data. Models also allow interpolation and extrapolation
- within certain limits
- and enable the search for conditions outside the range of known properties.

Given that this app is on a mobile platform, I find it rather impressive. I would like to see more chemical data, but love that I can manually input data for a chemical I need. This app reminds me of ChemCad and I would hope it keeps improving. Props to the developer!
Literally everything the desktop version can do, on your phone - who even does flowsheeting on a touchscreen?! Easy interchange between desktop and phone app for recalculating process changes in a meeting, on the go... Pipe segment add doesn't allow input as others have noted (Pixel 3, Android 10) only bug I've run into. Still more stable than Aspen. Be a little careful, paid phone app and desktop subscription features are not the same, get the T4 subscription if you want full access everywhere.
It seems like it'd be ideal for modelling processes I'm working with, but you can't easily add new compounds to the database. I'd expect to be able to give it a CAS ID, and have it load right up from the public database, but nope. Until I can get Levulinic Acid in this thing, it's as useful as a brick to me.
Overall an exellent tool although this should be an educational app. The features are locked unless you pay to unlock them and it is not even mentioned before you download it. If you are a student don't waste your time or your money.
I have purchased the paid android version installed on Samsung tab s 4 .. 1- There is problems in generating phase envelops for multi component hydrocarbon mixtures , 2- Also , there's problems in uploading my saves files ! When i try to upload a previous saved project , nothing appears and opens in the flow-sheet as if i have opened a blank flowsheet ! 3- there is problems in dragging different object tools to the flow-sheet Would you please fix these problems and bugs
App is very good and kudos. I belong to same Uni Dortmund ChE grad. Pipe hydraulic unit operation, we can not able to fill length and diameter as the window for edit hydraulic opens, it did not pop up keyboard automatically. Thanks and regards
done with learning. once i said cannot modify the pfd. but now it is okay, already find the way. good simulator. help me a lot.
Utterly useless. I paid to access the extra calculations I needed for my dissertationand every single calculation failed without explaining, why. Do not waste your time, or money
The references are awesome, and the chemical compound list is very complete! Thanks for helping scientists everywhere 😄
If you are a chemical engineer than this app is a must. With the rate at which this app is developing, I believe that Dwsim will become more popular than Aspen Plus.
Dwsim helps lots of students who wants to learn simulation. Thanks for that
Should we buy the package for better understanding.if so...what could be the cost details?
Very Easy to use , Very Good Simulator
Very nice 👍👍.. I not have words to express my self...👌👌👌👌👌 Many chemical engineering student not have laptop that can use this. My request to Daniel pls keep it up 🙏💯...
SUBSCRIBE "The Concept Guy" on YouTube for DWSIM tutorials. Thanks for such a great software .
Irritating app. it doesn't work at all
Report preview would be indescribably helpful.
Dear Mr. Daniel, The mobile version doesnt have the Cape Open and ChemSep options. When we get that options in the mobile version?
I have been having issues paying for the entire package. How can that be handled?
Demo should be provided for how to use ....it Now its working
Really, it's locked on this app uncool! 😠😠😠😠😠😠😡😡😡😡😡
I liked the app
Best
not able to edit hydraulic profile in pipe segment. Keypad dosent appear.. this problem not solved. I am facing another problem with sensitivity analysis tool, I was solving a problem on separator where change in inlet stream temp should change liq outlet flow.. but it dosent happen, however if I change the direct values in inlet temp then outlet liq flow changes.
It keeps telling me the peng Robinson fluid package is locked and no help in unlocking it either. Need help on this asap
Need a way to see component data base
Good app with lots of features. However it is difficult to figure out how to use it, as I couldn't find an android help/tutorial, which meant I was never able to calculate a mixture true critical point (index out of range error)
I re installed and looks like the earlier bug on compressor efficiency is fixed...i must say IT'S AN EXCELLENT APP WITH EXCELLENT GUI..KEEP IT UP GUYS..
An affordable, and truly capable, chemical process simulator. Being constantly updated and improved. Buying the full package is totally worth it.
A nice addition to the theory work and idea realisation in chemical engineering, being able to save the results as either text or pdf is invaluable as a time saver. Very useful for my university friends who need to see how a process will work with given variables such as temp and pump pressure ect. Also useful for my idle curiosity as to what effect a small change could have on a known process. One minor issue since the up date it doesn't work off line, keeps crashing and has to be force stopped
