RTD + Micromixing

7 important questions on RTD + Micromixing

What is the difference between micro-mixing and macro-mixing?

Understanding the distinction between these two types of mixing is essential in various applications.
  • Macro-mixing involves larger scales, focusing on homogeneity in large volumes.
  • Micro-mixing deals with small-scale mixing, ensuring uniformity at the particle level.
  • Macro-mixing might use slower processes, while micro-mixing requires faster actions.
  • Each leads to different reactions in chemical engineering and material science.

When has micromixing a bad influence on conversion?

When the reaction order n>1

What for influence has micormixing on 1st order reactions with conversion?

It has no effect on the conversion of a 1st order reaction.

What is complete segregation in a reactor?

The is no exchange between fluid elements.

What is ideal micro-mixing?

Complete inter-mixing of fluid-elements (down to molecular level).

What assumptions can you make about ideal micromixing

  1. Degree of segregation = 0
  2. RTD is insufficient if n not equal to 1 for exact calculation of the conversion
  3. Moment of mixing is important.

What assumptions can you make about Comeplete Segregation?

  1. Degree of segregation = 1
  2. RTD is sufficient for exact calculation of conversion
