    Separatory Funnel rotator

    It seems I am about to change line of work and go into R&D. I cannot specify too many details, but does anybody know manufacturers of separatory funnel rotators - to mix the contents of a funnel by rotating it around its axis? Shakers are relatively common, but rotators are more elusive. My...

    Elimination of Sulfuric Acid Mist

    The mist is from battery formation lines, not sulfuric acid plant or the like. Particle size comes from the data I have been provided with. I'm a bit rusty on the mist terminology: "d50 cut" means removal of 50% of the particles?

    Humidity Issues in Wet Scrubbers

    Yes, I designed the scrubber to take the humidity into account as well.

    Elimination of Sulfuric Acid Mist

    Yes, the scrubber will use a knit mesh mist eliminator above the liquid distributor.

    Elimination of Sulfuric Acid Mist

    I am in the process of designing a wet scrubber for the removal of sulfuric acid mist from exhaust air. This mist is reported as having particle size of 5 - 6 micrometers and specific gravity slightly above 1, while the packing manufacturer has data only for 7 - 12 micron particles at that...

    pH meter problem..help me.

    I worked for a while in pHmeter calibration and standard solution production. Yes, electrodes must be kept wet - better in a KCl solution if they are KCl electrodes. If the electrode is malfuctioning, it can have a dirty membrane that needs to be cleaned. But even if treated with the best...

    Humidity Issues in Wet Scrubbers

    I am tasked with designing a scrubber for fumes from a steel pickling plant. The HCl removal part is no big deal, but I am not sure what to do about the humidity. Fumes come at 60 °C, carrying a substantial amount of water vapor. If they are contacted with water around 35 °C, this vapor will...

    Acid gas scrubber with wash solution recycle

    It is a simple mass balance. At the steady state, the flow rate of salts with the discarded wash solution must be equal to the production rate by chemical reactions. Thus, steady-state concentration is controlled by the recirculation ratio.

    Acid gas scrubber with wash solution recycle

    No, I don't have Aspen Plus; I'm doing the design without specific software. But I found a solution in the meantime.

    Acid gas scrubber with wash solution recycle

    Greetings everyone. This is my first post here, but let's go straight to business. I am starting to work for an engineering company and my first project is to design a scrubber to remove HCl and SO2 from tail gas. The customer wants to use 10% NaOH in water with recycle of the wash solution...
