Pure water was used to remove 90% ammonia from the gas mixture in packed bed tower. The gas mixture which contain 5 mol% NH 3 enters from the bottom of the column at flow rate of 100 kmol/h. Pure water enters from the top of the column at a flow rate 1.5 times minimum pure water flow rate (1.5 Ľ min ). The column cross sectional area is 0.20 m 2. The equilibrium relationship for NH 3 and water is given by y 0.8915x. The film mass transfer coefficients are given as k' y a = 0.0739 kmol/s.m 3 and k' x a = 0.169 kmol/s.m 3. Determine the height of the packed tower using liquid film mass transfer coefficient, k' x a.

Transcribed Image Text:Pure water was used to remove 90% ammonia from the gas
mixture in packed bed tower. The gas
mixture which contain 5 mol% NH 3 enters from the bottom of the
column at flow rate of 100 kmol/h.
Pure water enters from the top of the column at a flow rate 1.5
times minimum pure water flow rate
(1.5 L min ). The column cross sectional area is 0.20 m 2. The
equilibrium relationship for NH 3 and water
is given by y =
given as k' y a = 0.0739 kmol/s.m 3 and
0.8915x. The film mass transfer coefficients are
k x a = 0.169 kmol/s.m 3 . Determine the height of the packed
tower using liquid film mass transfer
coefficient, k' x a.
