5. Isothermal Reactor Design: Conversion

Why, a four-year-old child could understand this. Someone get me a four-year-old child.

—Groucho Marx

Overview. Chapters 1 and 2 discussed mole balances on reactors and the manipulation of these balances to predict batch reaction times and flow reactor sizes. Chapter 3 discussed reactions and reaction-rate laws, and Chapter 4 discussed reaction stoichiometry. In Chapters 5 and 6, we combine reactions and reactors as we bring all the material in the preceding four chapters together to arrive at a logical structure for the design of various types of reactors. By using this structure, one should be able to solve reactor engineering problems by reasoning, rather than by memorizing numerous equations together ...

I’ve been on the O’Reilly platform for more than eight years. I use a couple of learning platforms, but I'm on O'Reilly more than anybody else. When you're there, you start learning. I'm never disappointed.

Amir M.

Data Platform Tech Lead

I'm always learning. So when I got on to O'Reilly, I was like a kid in a candy store. There are playlists. There are answers. There's on-demand training. It's worth its weight in gold, in terms of what it allows me to do.
