    Thermodynamic estimation of phases

    So far I have found and experimented a bit with: - Coolprop - Thermo - Cantera Also found this good link: https://kyleniemeyer.github.io/computational-thermo/content/mixtures/multicomponent-phase-equilibrium.html But I am still struggling with the theory...

    Thermodynamic estimation of phases

    Hi Latexman. Thanks for the good suggestions and the calculation but I am looking for a link to a way to calculate it by "hand" (in python probably). I have become way to dependent on simulators over the years that I have completely forgotten to do it manually.. I want to rediscover the core...

    Thermodynamic estimation of phases

    Hi Everyone. I am trying to understand how to determine the phase from the following list of inputs: total mole fraction of each species (as an example: 10 mol/h NH3 + 5 mol/h Water + 4 mol/h CO2) temperature (65 degC) pressure (4 barg) By doing hand calculations or a python algorithm. My...

    Tube side design temperature

    I do not agree with my colleagues in this post. Designs with different design temperature on the shell and tube can occur. To me it sounds like you have a water tube boiler. If the tubes of the water tube boiler is connected to a steam drum with natural circulation (no pumps which can fail)...

    Piping and instrumentation diagrams (P&IDs) workflow

    Hi everyone. In our company we are debating what is best practise for creating P&IDs (combined effort of a drafter and an engineer) with the least errors in the fastest time (Basic engineering P&IDs). There seems to be two schools: School A: - Draft the diagrams roughly and assign pipe, valve...
