When molasses is fermented to produce a liquor containing ethanol, a C02-rich vapor containing a small amount of ethanol is evolved. The alcohol will be recovered by countercurrent absorption with water in a packed-bed tower. The gas will enter the tower at a rate of 180 kmol/h, at 303 K and 110 kPa. The molar composition of the gas is 98% C02 and 2% ethanol. The required recovery of the alcohol is 97%. Pure liquid water at 303 K will enter the tower at the rate of 151.5 kmol/h, which is 50% above the minimum rate required for the specified recovery (Seader and Henley, 1998). The tower will be packed with 50-mm metal Hiflow rings and will be designed for a maximum pressure drop of 300 Pa/m of packed height. 

Now, we estimate the pressure drop for operation at 70% of flooding using the Billet and Schultes (1991a) correlation. From Table 4.1, for 50-mm metal Hiflow rings ... 

Consider the absorber of Examples 3.7 and 5.2. The adsorber will be packed with 50-mm metal Hiflow rings. Estimate the dimensions of the absorber and the power required to pump the gas and the liquid through the tower. Design for a gas-phase pressure drop of 300 Pa/m of packed height. 

Consider the ethanol absorber of Example 4.4, packed with 50-mm metal Hiflow rings. Estimate the packed height required to recover 97% of the alcohol, using pure water at a rate 50% above the minimum and with a gas-pressure drop of 300 Pa/m. The system ethanol-C02-water at the given temperature and pressure obeys Henry s... 

Air at 300 K is used to dry a plastic sheet. The solvent wetting the plastic is acetone. At the end of the dryer, the air leaves containing 2.0 mol% acetone. The acetone is to be recovered by absorption with water in a packed tower. The gas composition is to be reduced to 0.05 mol% acetone. The absorption will be isothermal because of cooling coils inside the tower. For the conditions of the absorber, the equilibrium relationship is y. = 1.8 c.. The rich gas enters the tower at a rate of 0.252 kg/s, and pure water enters the top at the rate of 0.34 kg/s. The tower is packed with 25-mm metal Hiflow rings. Determine the dimensions of the tower. 

Repeat Example 6.16 for a tower packed with 50-mm metal Hiflow rings. Design for a 70% approach to flooding. 

Hiflow rings, structured Sulzer gauze packings (type BX), as well as type X sheet metal packings and Montz packings X with flow channels of a = 30° resulted in a higher flooding point constant Cfi,o. compared to Eq. (2-64), namely ...
