Chemistry

1000 mol/min of a mixture of 90 mol% air and 10 mol% HCl entersan absorber column and is contacted with a stream of pure waterentering the column at the rate 300 moles/min. 90% of HCl in thefeed gas is absorbed by water. The two exit streams are gas stream(air+HCl) and liquid stream (water+HCl), respectively.
1. Draw and label a flowchart.
2. Define a basis of calculation.
3. Carry out a degree of freedom analysis and determine flowrates in mole/min and compositions in mole fractions of the exitstreams.
