    Pressure test passed but vacuum test failed

    Sorry, I mean flexibles yes, stainless steel, 60 degree cone fittings. I'll check with my supplier, thank tou

    Pressure test passed but vacuum test failed

    It's all under ambient temperature, and you can hear the leak whistle. I should add that the vessel is weighted so it's all connected with stainless steel hoses, 60 degree cone fittings

    Pressure test passed but vacuum test failed

    Hello everyone, My company is working on a vessel that can work under pressure (around 3-5barg) and under vacuum (-0.5barg), So far the positive pressure tests were successful with no leaks or pressure drops, but during the vacuum test, the pressure rises really quickly, Is this normal? My...

    What's the best way to dissolve CO2 in water in a continuous process at low pressure?

    It is continuous, it comes from venting at a certain section of the process, I don't have confirmation of the exact flowrate, a ballpark figure might be 50-100kg/h, A quill might work, it could be an option. Can't I use a sparger in a tank as long as I have enough residence time?

    What's the best way to dissolve CO2 in water in a continuous process at low pressure?

    I've been reading a bit regarding the solubility of CO2 in brine, and it seems that it decreases as you increase the salt concentration due to the salting-out effect, So on the one hand, solubility should increase by increasing the pH, due to equilibrium, but the salting out effect cancels...

    What's the best way to dissolve CO2 in water in a continuous process at low pressure?

    It doesn't have to be plain water no, we can add a base. Maybe a stirred tank with base dosage and a bubbling mechanism at the bottom would be a good method then.

    What's the best way to dissolve CO2 in water in a continuous process at low pressure?

    Hi all, I'm trying to dissolve a reasonable amount of CO2 into water to form carbonic acid (so no gas trapped in the liquid at high pressure), I was thinking of using some sort of absorption column to have a continuous process where CO2 is dissolved into the water, but I don't know if that's...
