Gas recirculation system in Nutsche filteration

Gas recirculation system in Nutsche filteration

Gas recirculation system in Nutsche filteration

(OP)
         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 ?

RE: Gas recirculation system in Nutsche filteration

the supplier of the nutsche should be able to help.  we control ours by adding or venting nitrogen on the discharge side of the machine.

we are typically at a few inches of water column on the discharge side and then at a vacuum on the suction of the liquid ring pump.

what pressure you run has a lot to do with what solvents you are drying or evaporating from the nutsche.

                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 ?
