Question
Membranes represent a relatively new technology for the separation of gases. One use that has attracted attention is the separation of nitrogen and oxygen from air. Figure 1 illustrates a nanoporous membrane that is made by coating a very thin layer of polymer on a porous graphite supporting layer. What is the composition of the waste stream if the waste stream amounts to 80% of the input stream? A selection containing 10% KCl, and 87% water is sod to the process shown in Figure, The rate of 18, 400 kg/hr. The compositions of the stream are following in percent. Evaporator product, P:NaCl: 16.8, Kcl: 21.6 H_2O: 61.6: Recycle R: Nacl: 18.9 and the balance water. Calculate the kilograms per hour and complete compositions of every stream.Explanation / Answer
Membranes represent a relatively new technology for the separation of gases. One use that has attracted attention is the enrichment of oxygen from air. The diagram below illustrates a nanoporous membrane that is made by coating a very thin layer of polymer on a porous graphite-supporting layer. What is the composition of the waste stream if its total flow amounts to 80% of the input? (The input and output compositions are given in mole percentages.)
answer= Waste stream contains 20 mol% O2. =
