The document discusses different types of reactor designs for single chemical reactions. It compares batch and plug flow reactors, mixed and plug flow reactors, and configurations of plug flow reactors in series and parallel. Plug flow reactors connected in series or parallel can achieve different conversion levels and product distributions compared to single reactors. The design should consider factors like reactor size, conversion level, and economic costs.

2. Today Design for single reactions ( Chapter 6 Levenspiel) 1- size comparison of batch and plug flow reactors 2- Mixed Vs Plug Flow Reactor 3- Plug Flow Reactors in Series and in parallel

3. Design for Single Reactions The requirements of a good design: 1- Experience 2- Engineering Judgment 3- Characteristics of different Reactor System Two main requirements in the reactor design are: 1- Reactor Size 2- Product Distribution in the reactor All the factors are judged on Economic Scale

4. 1- Batch Vs Plug Flow Reactor - Both have specific advantages and disadvantages - For a give conversion, both have same volume 2- Mixed Vs Plug Flow Reactor Consider the reaction: For Mixed flow reactor: For Plug Flow Reactor: Comparison.. Or

6. Graphical Comparison

7. Plug Flow Reactors in Series/Parallel Consider “N” plug flow reactors connected in series, then for any reactor, Or for N reactors, we may write as, Parallel Combinations: Parallel systems are adopted for constant space time through out. The feed is equally distributed in all the parallel reactors.
