A carbon steel material was selected for the
design of the scrubber wall, then from metals and
materials Table, the modulus of elasticity, E = 200.1 ×109
N/m2. But the collapsing pressure in the scrubbing
chamber is atmospheric, then Pe = 101.3× 103 N/m2.
Assuming a factor of safety of 2, Pe = 2 × (101.3 ×103) =
202.6 × 103 N/m2. The numerical coefficient, K =50 was
adopted from Garba [8]. The thickness, t has been
determined to be 0.0218m by using (2).
