Question
The NaOH contained in a CaCO3 sludge is washed back with water in a counter flow extractor. want to win. Sludge containing 44.3% inert (caCO3), 33.5% NaOH and 22.2% water 1000 It is fed at a flow rate of kg/h. The upstream leaving the extractor should contain 15% NaOH and be fed. 95% of NaOH is desired to be recovered. In addition, using the following data Calculate the required amount of water (supplied) and the ideal number of stages. Assume that the concentration of the solution and the concentration of the solution carried by the sludge are the same. It is estimated that the sludge leaving the extractor carries 660 kg of water.
