Engineers in the field known as “chemical” employ economics, statistics, biology, microbiology, and biochemistry, as well as physics and chemistry, to find solutions to real-world issues. Chemical engineers are unique in that they draw on chemistry knowledge in addition to their engineering expertise. Since their knowledge of science and technology is so scientific, chemical engineers are often referred to as “universal engineers.” Chemical engineers often possess the degree in Chemical Engineering as well as Process Engineering. Engineers in the field may be recognised members of professional organisation and in possession of relevant professional credentials. Over the years, chemical engineering has maintained its position as one of the best paying branches of engineering. Chemical engineers are in high demand in a wide variety of industries, from the more classic ones like chemicals and plastics to newer ones like electronics and consumer goods to mining and metals extraction and even biomedical implants and power production. This book was created with basic introduction in chemical engineering in mind, hence it is aimed largely towards undergraduate students taking those courses. It’s designed for college grads entering the workforce and realising they need further training in unit operations and structural design.
