The catalyst regeneration unit in an oil refinery is generating a flue gas containing air and dust particles. The flue gas flow rate is

6(m^(3))/(s)

at

200\deg C

and 1 atm . The density of flue gas is

1.2k(g)/(m^(3))

and the density of dust particles is

2000k(g)/(m^(3))

. The viscosity of flue gas is

1.8\times 10^(-5)k(g)/(m).s

. Design a settling chamber that can be used to remove

80%

of

60\mu m

particles for regulatory compliance. The recommended gas velocity passing through the effective chamber is

3(m)/(s)

. The available floor space is 2 m wide and 5 m long. ***Calculation of Re to identify type of gas flow in the chamber is required. Show your analysis and provide the following design information. (15 marks)

?

A sketch with dimensions of the effective chamber (width, length and height)

?

If you choose to insert horizontal plates in the chamber, you must identify mumber of horizontal plates and plate spacing.
