Problems 8 and 9 are based on the following information: It is required to dry natural gas containing 80 lbs of water per 106t3 by passing it through a bed of activated alumina gel in two adsorption towers. Data: Natural gas to be dried =1106f3/ day (24hrs) Density of the alumina gel =50lb/ft Economic adsorption factor =4% water by weight (dry basis) Critical gas velocity through the tower =35fpm Temperature of natural gas =50F Pressure =225 psia Economic adsorption factor refers to the amount of adsorbate per amount of adsorbent used. The height of the tower is a. 14.9ft c. 15.9ft b. 10.8ft d. 1.34ft
