R.T.D Studies In Plug Flow Tubular Reactor Apparatus

Real reactors do not satisfy the idealized flow patterns, back mix flow or plug flow deviation from ideality can be due to channeling of fluid through the vessel, recycling of fluid within the vessel, or due to the presence of stagnant region or pockets of fluid in the vessel.


Description

Real reactors do not satisfy the idealized flow patterns, back mix flow or plug flow deviation from ideality can be due to channeling of fluid through the vessel, recycling of fluid within the vessel, or due to the presence of stagnant region or pockets of fluid in the vessel. To predict the exact behavior of a vessel as a Chemicals reactor, RTD or stimulus-response technique is used. The setup consists of one feed tank through which water is fed to the reactor. The flow rate can be adjusted by operating the needle valve and measured by Rotameter. Compressed air is used for the circulation of feed. A straight tube-type reactor is kept horizontally and inclined upward at the outlet from where samples are collected for analysis. For understanding the R.T.D. characteristics, a special arrangement to inject tracer into the lower end of the reactor, using a syringe is provided. Pressure Regulator & Pressure Gauge are fitted in the compressed airline
