AbstractWith increasing nitrogen purity, PSA plants require an over-proportional air demand with the consequence that high-purity PSA systems engender a distinct interest in energy-saving measures. This paper presents process intensification strategies with the focus on a reduced energy consumption. Therefore, the influence of PSA configuration and cycle organisation on process performance was investigated. Results are presented at two product purity levels (10 ppm/1000 ppm O2) and two operating temperatures (25 °C/45 °C) in a lab-scale twin bed PSA (2 × 2 L). It is shown that dedicated strategies are available to intensify the PSA process; however, their effects are dependent on ambient conditions and product purity levels.

Drying Rates

Intermittent drying is an operation that aims to improve drying process performance with modulations of inlet air conditions such as its temperature and velocity, contrary to the conventional operation, in which air conditions are constant. This alternative operation aims to determine the best modulation pattern of air conditions to minimize energy consumption, maximize dryer performance or improve material quality. In this context, the objectives of this work are to simulate the drying process of some grains in fixed bed and assess if it is possible to enhance the dryer performance in terms of drying rates under intermittent operation in comparison with results obtained with conventional operation. Both intermittent and conventional operations were simulated with the same energy consumption related to the energy supplied by the air at the dryer entrance. Results revealed that the drying rates were higher under intermittence of inlet air temperature in comparison with results obtained under conventional operation with constant inlet air temperature. In addition, it was observed in some simulations that the amplitude and period values related to modulations can impact on drying rates.
