    Multivariable optimization

    Thanks m777182: The optimization model I am working on is deterministic (based on first principles) and not of the data mining type (which relies on actual plant data). Of course I have to make certain simplifying assumptions (temperature uniformity within a CSTR, transverse uniformity in a PFR...

    Multi Effect Evaporator

    CARF, Neat animation. What software do you use ? My own process model uses Excel. Calculations and macros are easy to program but I am not sure I can achieve the same level of sophistication in animation. Many years ago I use a 5-effect evaporator system for Ethylene Glycol/ water concentration.

    Plastic Properties

    The task you have at hand is very challenging. Density depends on the nature of the base resin and of the additives. Bulk density depends on the size and shape of the pellets. The smaller the pellets the higher the bulk density. Izod: I assume you are dealing with rubber toughened plastics. It...

    Multivariable optimization

    Thanks jmw for the tip on Taguchi. I will investigate. For MFI we use the offline method. MFI test takes only 15 min. so it is not too difficult. For Polyethylene some people have used a benchtop NMR. Bruker claimed that they can determine MFI quite accurately. Such spectrometric method work on...

    Multivariable optimization

    I want to optimize a (polymer) process consisting of say 5 isothermal reactors in series (the actual process has a recycle stream and other complications but these can be dealt separately). The process is continuous. How can I maximize the production of polymer by playing with the 5 reactor...
