    Minimum N2 flow in relief header to prevent reverse flow

    I'm looking at a 24" relief header which goes to a knock out pot before entering a scrubber. The knock out pot contain a corrosive medium and we would like to prevent the acidic gases diffusing back into the relief header. At the moment I'm thinking 2 to 3 cm/s should be enough but I was...

    Online Dielectric Constant Measurement

    Thanks for this. I would never have found it just searching myself. Need to think about how it could be placed in an ATEX zone.

    Online Dielectric Constant Measurement

    Hello, We have done some work in the lab to look at how the dielectric constant changes with isomer content. Its a 2 component mixture and the temperature corrected correlation looks quite good. Now we would like to implement this on the plant but we are having difficulty finding a supplier...

    NPSHa with dissolved N2

    Thank you for your replies. Although it will mean a change to the layout we still have the option of increasing the static height to the pump so I will propose that we only account for elevation head to be on the safe side.

    NPSHa with dissolved N2

    I was hoping someone on this forum may help with a question I have. I have a condenser that runs off into a flash vessel. The vapour then goes off to a vacuum pump and the liquid to a gear pump. The flash vessel runs at 0.4bar and the vapour pressure of the solvent is 0.04bar. The question is...
