In addition, counter current dryer provides higher residence time for particles within the drying chamber.
Counter current spray drying was suitable in producing well defined crystalline lactose particles mainly due to the higher residence time.
The results show that a reactor temperature of 1373 1473 K and high residence time favors the production of syngas at high conversion efficiency of acid gas.
Majority of the existing direct-contact liquid desiccant dehumidification modules adopt the concept of low influx rates which ensures high residence time resulting in improved dehumidifier performance.
Furthermore the particle size distribution is important for the system design, because limestone with larger size needs significantly higher residence time in the calcination zone for full conversion.
Therefore, the spatial structure characteristic of artificial reefs seems to enhance anthropogenic litter accumulation, also leading to higher residence time and degradation potential.
A major difference in these pathways was the amount of dye that traveled close to the sleeve, i.e., a zone of higher residence time and higher UV exposure.
However, past studies have shown many concerning issues in regard to the use of batch process such as high residence time, product inconsistencies across batches, high labor cost and difficulty in industrial scale up.
At excess air of 40 60%, the bed temperature in the advanced conical FBC was substantially, by about 180 °C, higher than that in the pilot combustor, mainly, due to better fuel air mixing and higher residence time of reactants.
