    Heat Exchanger Overpressurisation

    Hi, I wanted to get peoples thoughts on potential for a BLEVE like scenario on a bank of heat exchagers. For a BLEVE we assume we need a level within the 'vessel' and a form of heating most likely a pool fire. On the heat exchanger bank the most likely cause of pool fire would be through a...

    Latent Heat in HYSYS for multicomponent mixture

    Guys, firstly thank you all for your input into this thread. TO give you abit more background, I work for the client and am currectly reviewing PSV calcs which have been completed by an outside consultant, namely looking at those which have highlighted anomalies where a suggestion that a valve...

    Latent Heat in HYSYS for multicomponent mixture

    Should the latent heat value (mass heat of vap) not change as I alter the vap fraction ? Surely the latent heat value should change as the vap fract increase(temp therefore increases) heavier end start to vapourize off? Is the latent heat for the mixture or simply for the light ends? at bubble...

    Latent Heat in HYSYS for multicomponent mixture

    Hi I am trying to get a value for latent heat of a mixture. I require the latent heat to use in W=Q/L to give me a required relief rate. I have a few questions which noone can really seem to answer : 1 - If i copy my stream and set vap fract to 0.01, the mass heat of vap displayed in the...
