化学工程师运用化学原理来解决涉及化学品和其他产品生产或使用的问题。他们设计用于大型化学制造的设备和过程，计划和测试制造产品和处理副产品的方法，并监督生产。化学工程师还从事化学制造以外的各种制造行业的工作，例如生产能源，电子，食品，服装和造纸的那些。此外，他们还从事医疗保健，生物技术和商业服务。化学工程师应用物理，数学，机械和电气工程以及化学原理。有些可能专门研究特定的化学过程，例如氧化或聚合。其他人则专门研究特定领域，例如纳米材料或特定产品的开发。他们必须了解化学制造的各个方面，以及制造过程如何影响环境以
Chemical engineers apply the principles of chemistry to solve problems involving the production or use of chemicals and other products. They design equipment and processes for large-scale chemical manufacturing, plan and test methods of manufacturing products and treating byproducts, and supervise production. Chemical engineers also work in a variety of manufacturing industries other than chemical manufacturing, such as those producing energy, electronics, food, clothing, and paper. In addition, they work in healthcare, biotechnology, and business services. Chemical engineers apply principles of physics, mathematics, and mechanical and electrical engineering, as well as chemistry. Some may specialize in a particular chemical process, such as oxidation or polymerization. Others specialize in a particular field, such as nanomaterials, or in the development of specific products. They must be aware of all aspects of chemical manufacturing and how the manufacturing process affects the environment and the safety of workers and consumers.
