R.T.D. STUDIES IN PACKED BED REACTOR APPARATUS

Axial diffusion and dispersion offluid in packed beds are important for design and operation of separationequipment and Chemicals reactors. The tracer technique, the most widely usedmethod for the study of axial dispersion.

In stimulus response experimentation,we perturb the system using pulse input of tracer and then see how the systemreacts or responds to this stimulus.

The analysis of the response givesthe desired information about the system. The setup consists of a glass columnpacked with Rasching Rings and one feed tank. Water is fed to the reactorthrough liquid distributor, fitted at the bottom of the column.

Rotameter is provided to measure theflow of water. The flow rate can be adjusted by operating the needle valveprovided on Rotameter. For understanding the R.T.D. characteristics, a specialarrangement to inject tracer into the lower end of reactor, using a syringe, isprovided. Samples can be taken periodically from the top outlet of reactor.Pressure Regulator & Pressure Gauge are fitted in the compressed air line.
