In a contact sulphuric acid plant, the secondary converter is a tray type converter 2.3m in diameter with the catalyst arranged in three layers, each 0.45m thick. The catalyst is in the form of cylindrical pellets 9.5mm in diameter and 9.5mm long. The voidage fraction is 0.35. The gas enters the converter at 675 K and leaves at 720K. Its inlet composition is SO3 6.6% ; SO₂ 1.7% ; 02 10.0%; N2 81.7% Its exit composition is SO3 8.2% ; SO₂ 0.2% ; If the gas O2 9.3%; N2 82.3% flow rate is 0.68 kg/m²s, calculate the pressure drop through the converter.

Transcribed Image Text:In a contact sulphuric acid plant, the secondary converter is a tray type converter 2.3m in
diameter with the catalyst arranged in three layers, each 0.45m thick. The catalyst is in the
form of cylindrical pellets 9.5mm in diameter and 9.5mm long. The voidage fraction is 0.35.
The gas enters the converter at 675 K and leaves at 720K. Its inlet composition is
SO3 6.6% ;
SO₂ 1.7% ; 02 10.0%; N2 81.7%
Its exit composition is
SO3 8.2% ; SO₂ 0.2% ;
If the
gas
O2 9.3%; N2 82.3%
flow rate is 0.68 kg/m²s, calculate the pressure drop through the converter.
