The technical and economic performance of an energy-integrated temperature swing adsorption process was analyzed. The new process allows the dryer to recover the pressure energy of the compressed air used as a purge gas, and thereby achieving economically practical energy conservation. To understand the effects of the retrofit from the conventional process to the energy-integrated process on the dryer performance, the two processes were numerically studied. The operation parameters of the energy-integrated process were determined from a provided dryer by a design procedure, of which the purpose is to ensure that the two processes have comparable regeneration effects. In conclusion, the energy-integrated process reduces by about 37.5% of electricity consumption compared with the conventional process. The economic analysis shows that the incremental investment for the retrofit from the conventional process to the energy-integrated process is effective since the payback period is less than one year.
