Abstract

This paper has dealt with water vapor desorption characteristics of powder type organic sorbent in an air fluidized bed. The Powder type organic sorbent was fluidized in a rectangular vessel by a humid air flow. The desorption rate of vapor and the variation in temperature in the sorbent bed were measured under various air temperature and humidity conditions. It was found that the air pressure loss of the fluidized sorbent layer increased with in an increase in water vapor concentration. Finally Sherwood number for mass transfer was correlated by means of Reynolds number,modified Stefan number. The ratio of sorbent particle diameter to the fluidized bed height and Schmidt number.
