Some people use science to make new things. 


Chemical engineers use science to make many things. They take raw materials and change them into products. 
Some engineers focus on products. They make food, drinks, or soaps. They also make medicine to help people. Other engineers work on new technology. They might study fuel cells or tiny nanotechnology. 
History shows us many great thinkers. Johann Rudolf Glauber made ways to make acids. 
Today, this job is very important. In the US, many women study this field. In fact, 35% of chemical engineering students are women. This is more than other engineering jobs. The job helps us make strong materials for cars and planes. It also helps us make parts for medical use.
Chemical engineers are experts who use science to make things. They take raw materials and change them into useful products. 

This job involves many different steps. First, an engineer designs the machines and the plant. Next, they build the equipment used for making products. Then, they operate the plant to turn raw materials into something new. They might make medicines or things like cosmetics and cleaners. Some even work on new technologies like hydrogen power. They might also work with tiny nanotechnology. 
History shows us how this field began. People debate who was the very first chemical engineer. Some suggest Johann Rudolf Glauber from the 1600s. 
There are many interesting facts about this career. In the United States, the median salary was about $127,000 in 2015. By 2017, the median salary was $124,000. In the United Kingdom, the median salary was about £57,000 in 2016. Many women study this field in the United States. About 35% of chemical engineering students are women. This is a higher percentage than in other engineering areas. The job is expected to grow by 3% through 2034.
You can see chemical engineering in your daily life. It is used to make medical implants and prosthetics. Engineers also work on biological projects like mapping the human genome. They study biopolymers, which are natural substances like proteins. Even the fuel in a car might involve their work. They help create the films used in electronic devices. 
A chemical engineer is a professional who uses chemistry and other sciences to solve problems. They specialize in converting basic raw materials into a wide variety of useful products. This work involves the design, construction, and operation of large industrial facilities called plants. 
The work of a chemical engineer follows a specific sequence of technical tasks. First, they engage in design, where they plan the machinery and the layout of a plant. Next, they focus on the manufacture and construction of that equipment. Once the plant is built, they move into the operation phase. In this stage, they manage the actual processes that turn raw ingredients into finished goods. 
There are several distinct types of engineers within this field. Chemical process engineers focus on the design and operation of plants and machinery. They often specialize in two complementary areas: chemical reaction engineering and separation processes. Chemical product engineers take a different approach. They focus on developing new or adapted substances for specific items. These products can range from foods and beverages to cosmetics, cleaners, and pharmaceutical ingredients.
Modern chemical engineering has expanded into many advanced scientific disciplines. Many engineers now work in materials science or polymer engineering. Others contribute to biomedical engineering, where they work on biological projects. This might include studying biopolymers, such as proteins, or mapping the human genome. They also develop new technologies like fuel cells, hydrogen power, and nanotechnology. 
The history of this profession is a subject of some debate. Some historians suggest Johann Rudolf Glauber was an early pioneer. 
Professional organizations have helped the field grow over the last century. The American Institute of Chemical Engineers (AIChE) was established in 1908. In the United Kingdom, the Institution of Chemical Engineers has a long history of defining the profession. By 1924, the UK institution defined the role as managing works where matter undergoes changes in state and composition. These organizations provide structure for a field that continues to evolve with new technologies.
Chemical engineering has a significant impact on the global economy and workforce. In the United States, the median annual salary was approximately $127,000 in 2015. By 2017, this median salary was recorded at $124,000. In the United Kingdom, the 2016 median salary was about £57,000. Salaries can vary greatly based on experience. For example, those with fewer than three years of experience earned around $70,450 in the US. Meanwhile, those with over 40 years of experience earned about $156,000.
The field also shows interesting trends in diversity and growth. In the United States, chemical engineering has a high participation of women. As of 2024, women make up 35% of students in this discipline. This is higher than the 20% seen in other engineering fields. The profession is also expected to see steady growth. The U.S. Bureau of Labor Statistics predicts a 3% growth in the occupation between 2024 and 2034. From creating ultra-strong fibers for vehicles to developing medical implants, chemical engineers remain essential to modern life.
