What do Chemical Engineers Do?

Chemical Enginers solve these kinds of problems:– How can make more gasoline?– How can we reduce pollution?– How do I design an artificial kidney?– How do make paint?– How do I make medicine?– How make plastics from corn?– How do we make ice cream?

Chemical Engineers Scale Up chemical processes

From the laboratory, to the plant

How do we make ice cream?

What do we need to make ice cream?9,200 pounds of ice cream or

1,100 gallons of ice cream

Can You Read an Engineering Drawing?

Why can’t we pump the ice cream into cartons?

Why did I become an Engineer?

Fourth grade teachers—Miss Todd – arithmetic —Mrs. Van Horn – science

Mom and Dad—“The Boy Scientist”—“Our Friend the Atom”—Chemistry set

Why did I become an Engineer?

I liked: math (calculating stuff) science (knowing why stuff works) taking things apart making things reading and writing

Mostly, I like people!

What have I done as a Chemical Engineer? Made cancer medicines Developed pollution control systems Made plastics Built chemical plants

– Cement plant – burned waste as fuel– Carbon nanotube production plant– Plastics plant

Designed a process to make plastics from corn Taught college (part time) Published over 150 papers and presentations
