Drying is a process of removing water from a solid object by a moving air stream. The efficiency of a drying process is highly dependent on the entering air properties. (a) In your own words, discuss the effect of the following parameters on the drying efficiency: i. ii. Relative humidity of air Air dry bulb temperature Air wet bulb temperature iii. It is desired to dehumidify the ambient air before entering a dryer. The dehumidification process aims to remove 70% of the water content in the air. The air must reach a relative humidity of 10% before entering the dryer. If the ambient air has a dry-bulb temperature of 35.5 C and a relative humidity of 70% RH: (b) Using the psychrometric chart, determine the dry bulb temperature and absolute humidity of the air entering the dryer (dehumidified air). (c) Design a dehumidification process using a labeled flow diagram by including the following: i. Plot the dehumidification flow process on the psychrometric chart. Detail all relevant unit operations of the proposed dehumidification ii. iii. process. Discuss the purpose of the selected unit operation in your process. Show all properties of the air stream at every stage output from the unit operation detailed in part (c, ii) iv
