Fortunately this concept has also been applied to the human body. The results of such analysis have helped improve clinical care , suggested improvements in diagnostic and therapeutic devices , and led to mechanical wonders such as artificial organs . Medical doctors and chemical engineers continue to work hand in hand to help us live longer fuller lives . Today's low price, high volume, drugs owe their existence to the work of chemical engineers. Synthetic fibers also help reduce the strain on natural sources of cotton and wool , and can be tailored to specific applications.
Chemical engineers can then separate out the different components.
The purified nitrogen can be used to recover petroleum, freeze food, produce semiconductors, or prevent unwanted reactions while oxygen is used to make steel, smelt copper, weld metals together, and support the lives of patients in hospitals. Catalytic converters , reformulated gasoline , and smoke stack scrubbers all help keep the world clean. Additionally, chemical engineers help reduce the strain on natural materials through synthetic replacements , more efficient processing , and new recycling technologies. Chemical fertilizers can help provide these nutrients to crops, which in turn provide us with a bountiful and balanced diet . Advances in biotechnology also offer the potential to further increase worldwide food production.
