Hydrogen sulfide (H2S) gas in petroleum refinery is to be removed from a 1387kg/h gas mixture consist of 16 % w.w H2S into air, using counter current absorption column.
Water is used as solvent in the absorption column. The water flow rate is 3 times the gas mixture flow rate.
The air mole percent at the top of the column is 97.5%.
The air consists of 21.9% oxygen and 78.1% nitrogen.
Calculate;
1. To H2S molar flow rate and mole fraction entered into the bottom of the column?
Note; Don’t round numbers; Minimum 4 decimals (0.0000)
Given
A) The air consists of 21.9% oxygen and 78.1% nitrogen.
B) The atomic weight of;
1. The hydrogen atom is 1
2. The Oxygen atom is 16
3. The sulfur atom is 32
4. 1The nitrogen atom is 14
