Notes

· chemical engineers are comfortable with chemistry
· Sadi Carnot was the first to study the thermodynamics of combustion reactions in steam engines
· Chemical engineering grew out of mechanical engineering in the 19th century
· industrial chemicals were mainly produced through batch processing
· some chemical engineers are known as universal engineers
· known as universal engineers because their scientific and technical mastery is so broad
· chemical engineering is a process of turning raw materials or chemicals into a more useful or valuable form
· raw materials are found in nature
