Question

Hydrogen sulfide (H2S) gas in petroleum refinery is to be removed from a 984 kg/h gas mixture consist of 25 % w.w H2S into air, using counter current absorption column.

Water is used as solvent in the absorption column. The water flow rate is 1.81 times the gas mixture flow rate.

The air mole percent at the top of the column is 96.5%.

 

The air consists of 21.9% oxygen and 78.1% nitrogen.

 

Calculate;

quantity and percent of H2S absorbed in 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
