Process systems engineering

Imagine you are playing with a set of building blocks. You have different shapes and sizes, and you can stack them on top of each other to make a tall tower. In process systems engineering, instead of building a tower, we build something called a "process."

A process is a way of making something, like making cookies or making gasoline for cars. Just like when you build a tower with your blocks, there are different parts to a process, and they all have to fit together just right.

Process systems engineering is like being really good at building with blocks. People who do process systems engineering are very good at designing and putting together all the different parts of a process, like the machines and pipes and valves. They have to think about things like how much of each ingredient to use, or how hot something needs to be.

But just like with building blocks, sometimes things don't work perfectly the first time. Maybe a block falls over, or a machine doesn't work. Process systems engineers are very good at troubleshooting - that means they can figure out what went wrong and how to fix it so that the process keeps working smoothly.

So, process systems engineering is like building with blocks, but instead of making a tower, we build processes for making things like cookies or gasoline. And process systems engineers are really good at designing and fixing all the different parts of the process.
