 Regeneration of silica gel in multi-shelf regeneratorSukhmeet Singh and Parm Pal Singh Renewable Energy, 1998, vol. 13, issue 1, 105-119 Abstract: In the present paper an investigation on the regeneration of solid desiccant (silica gel) in a modified design of dehumidifier called “Multi-shelf Dehumidifier”, has been reported. A “Packed Bed Dehumidifier” was used as control. Both the dehumidifiers were fabricated and tested simultaneously. The effect of regeneration air temperature, bed-air velocity and number of shelves on regeneration of silica gel was investigated. The range of regeneration air temperature was 42–72°C, while bed-air velocity varied from 0.175-0.55 m/s and number of shelves from 2 to 4. The regeneration time decreased with the increase in regeneration air temperature, bed-air velocity as well as number of shelves. The values of regeneration air temperature and bed-air velocity for minimum energy input were found to be 52°C and 0.175 m/s irrespective of the number of shelves. The effect of the rest period was investigated for these optimum values of regeneration air temperature and air velocity for a number of shelves varying from 2 to 4. The rest periods used were 30, 60 and 180 mins. The regeneration time reduced with increase in rest period for all the values of number of shelves, but the reduction in regeneration time was not appreciable.
