sulfuric Acid Regeneration

We are a manufacturer of LABSA. In the process we generate spent sulfuric Acid, which is around 72% to 78% active with impurities & black in colour. We want to regenerate this spent sulfuric Acid (72%-78%) to sulfuric Acid (98%). Pl let us know, if you can provide us any information for this process.

Hi Apurva,

On your particular process, I've never run into that before.

You could try to 'evaporate' the sulfuric and pass the emissions through an ordinary l2 micron blade type mist eliminator.

You'd achieve 2 things. One is the capture/knock-out of any black or whatever particles, secondly the concentration might rise.

This eliminator would have to be made from uPVC throughout which is somewhat temperature sensitive !

It is virtually totally dependent on what the impurities are.
Not many places find it cost effective to recycle.
