    Estimation of kinetic parameters using Aspen plus

    Hello, I am trying to simulate the reactions of methylene urea production using Aspen plus. I have the reactions but I dont have the kinetic data like ko(pre-exponential factor) and activation energy values. Is there some way to get these parameters from Aspen plus ? Thanks in advance ...

    Sour water stripper unit

    Thank you @PaoloPemi..I will go through the paper @georgeverghese..The company doesn't have a pro-II license...It was already designed a few years back.Now I have to check its adequacy if another stream of around 15m3 is also going into this stripper unit..like changes in reboiler duty, will...

    Sour water stripper unit

    Yes @shvet I am trying to get the test run data so that I can compare and model it better. Any reading material on sour water stripper process chemistry ?? Thank You !!

    Sour water stripper unit

    Thank you for your prompt response !! The unit has already been designed and is under commissioning...I am simulating it because i need to see the change in reboiler duty, Pa duty, when another waste stream containing ammonia and h2s is also sent to this unit..if the existing unit can handle it...

    Sour water stripper unit

    Hello I am trying to simulate a 2-stage sour water unit using Aspen Hysys...I have used sour PR package...There is no access to other simulation software like protreat/promax Both the stripper columns have pumparounds..The number of trays in each column are 47...The pumparound draw is taken...

    Hello I have to calculate area req

    I will try to get it But as of now I don't have any PFD & PID with me Thank you !!

    Hello I have to calculate area req

    It is an orifice plate and has multiple holes (as i mentioned in my first post). I know the pressure that is to be maintained downstream of the orifice...I have to size the orifice and check how much is the back pressure in the nozzle and check upstream pressure required...the criteria is that...

    Hello I have to calculate area req

    Application is crude and steam are passed through a nozzle...which has an orifice at the outlet of the nozzle...downstream pressure of nozzle is fixed..

    Hello I have to calculate area req

    Thank you @shvet...yes these two combinations are enitrely different...even in my case when steam is added to the crude, some hydrocarbons vaporize...

    Hello I have to calculate area req

    Not very precise Approximate value is okay(within 10-15%)
