5 An air stripping tower is to be designed to lower the ethylbenzene (C,H0) concentration in a contaminated groundwater from 5 mg/L to 30 ug/L. The water flow rate is 700 m /d, the mass transfer coefficient (K, a) for ethylbenzene is 0.015 s-1, and the dimensionless Henry's constant for toluene is 0.27. Assume a stripping factor of 3 and packing factor of 40 and a pressure drop of 100 N/(m2.m). The air and water temperature are 20°C, resulting in p, = 998.2 kg/m', P= 1.204 kg/m', and = 1.002 x 10-3 N-s/m2. Determine the following: a. Theoretical air flow rate (m'/min). b. Diameter of the stripping tower (m). c. Height of the stripping tower (m). %3D %3D

A fireplace is a chamber, made of different materials usually constructed to contain the fire for various applications. A fireplace is often known as a hearth. Fireplaces can be made of bricks, steel, stone, and concrete. Fireplaces serve as room heaters…
