    Gas recirculation system in Nutsche filteration

    The solvent is heptane & intention to run suction/ discharge side at atmospheric/0.5 bar g. with a heptane ring pump; before speaking to Nutsche vendors some operational details ?

    Gas recirculation system in Nutsche filteration

    I was trying to figure-out how the pressures (both in the filterate receiver & the Nutsche itself) are controlled during the various stages of a filteration when using a liquid-ring compressor for subj.. Anyone with experience in this operation ?

    Oxygen & hydrogen measurement inside of batch reactor

    In the controlled space, the expected concentrations for both oxygen & hydrogen are 0 - 10% with a max. of 2000mbar (abs) pressure.

    Filter on Cooling Tower Sidestream

    A side-stream self-cleaning pressure filter does a very good job; u fit it & forget it. I have used it with satisfaction.

    External-gear-pump operation.

    If in an existing installation for diesel pumping with subj. type pump the diesel is replaced with water, will there be a substantial difference in the discharge pressure ?

    Pumping hazardous liquid.

    We have a horizontal tank for storing phosphorous trichloride; a very hazardous chemical that allows for only top entry & so we use a submersible pump with mech. seal. The afore mentioned mech. seal however often fails. Are seal-less/magnetic drive submersible pumps available ? Some reputed...

    Recycling blowing agent (having solvent) from Nutsche filters.

    In blowing the filter cake in our Nutsche filter with nitrogen significant quantities of solvent (Isopropanol) are lost. Is there an established technology whereby both the gas & solvent can be recycled ?

    Calculating solvent losses in a batch vacuum distillation.

    In a batch process kettle with overhead condensors connected to single stage steam ejector for vacuum generation I would like to calculate how much xylene (the only low boiler) would be lost from the reactor at kettle vacuum of 150 mbar. & 110 deg. C. (ejector side vacuum 0 mbar). Any ideas...

    Request for help on accurate steam flow measurement.

    Presently we are using a 4" Vortex flowmeter that is generating high error which the manufacturer says is due to oversizing of meter. The flow varies between 600 to 3000 Kg/hr.. Is there a meter that can cover this range accurately ?

    Calculating power consumption from knowing suction & disch. pressures

    Is it not possible to calculate the TDH knowing both suction & disch. pressures ? Would the difference between the two not be the TDH ?

    Calculating power consumption from knowing suction & disch. pressures

    Thanks Tstead but I made a small mistake in my post. I said I knew the flow but that was wrong. Actually I would like to calculate the flow knowing the suction & discharge pressures.
