Abstract

A simulation model for energy consumption sensitivity analysis is developed for an adsorption dryer utilizing the released heat of adsorption for drying. The system is optimized with respect to the regeneration air inlet temperature, ratio of adsorbent to drying air flowrate and ratio of regeneration air to adsorbent flowrate. The exhaust streams of the process under these optimal operating conditions are analyzed for sensible and latent heat recovery potentials. Using zeolite as adsorbent, it is shown that by proper selection of the optimization variables and recovery of stream energies, the system’s energy performance for low drying temperatures is improved considerably.
