A CSTR is being used to carry out a certain reaction isothermally in the liquid phase.It is observed that the conversion in the CSTR is actually higher than that which was predicted from the design equations. It is also determined that the CSTR is not very well-mixed. Could this explain the observation of high conversion? If so, explain how.

Respuesta :

Answer: Yes

Explanation:

In a stirred Tank Reactor (CSTR), deviations from perfect mixing can occur both on macro and micro scales. The macro scale deviations are engrossed by the deviation of the residence time distribution (RTD) from a well stirred residence time distribution (WS RTD). A number of models for incomplete mixing in a CSTR is used to cover the micro mixing deviations from maximum mixedness. The Rippin-Ng random mixing model and Weinstein's Consecutive Reactor model are good models for incomplete mixing in a single CSTR. From the question asked, it is obvious that the conversion in the CSTR is actually higher than that which was predicted from the design equations. There is also a possibility that the CSTR is not very well-mixed. This explains the observation of high conversion.
