化学工程（ChE）涉及涉及材料的化学和/或物理变化的过程的开发，应用和操作。化学工程师的工作是分析，开发，设计，控制，构造和/或监督研究，开发，中试规模操作和工业生产中的化学过程。重点放在将计算机分析应用于上述领域中遇到的问题上。化学工程师受雇于制造无机化学品（例如酸，碱，颜料和肥料），有机化学品（例如石化，聚合物，燃料，推进剂，药品和特种化学品），生物产品（例如酶，疫苗，生物化学制品，生物燃料等），食品，半导体和纸张。具有研究生学位的研究生化学工程师在各种需要其技术技能的组织中工作。这些组织可能包括：地
Chemical engineering (ChE) encompasses the development, application, and operation of the processes in which chemical and/or physical changes of material are involved. The work of a chemical engineer is to analyze, develop, design, control, construct, and/or supervise chemical processes in research and development, pilot-scale operations, and industrial production. Emphasis is placed on the application of computer analysis to problems encountered in the above areas. Chemical engineers are employed in the manufacture of inorganic chemicals (i.e., acids, alkalis, pigments, and fertilizers), organic chemicals (i.e., petrochemicals, polymers, fuels, propellants, pharmaceuticals, and specialty chemicals), biological products (i.e., enzymes, vaccines, biochemicals, biofuels, etc.), foods, semiconductors, and paper.<br><br>Graduate-level chemical engineers with graduate degrees work in a wide range of organizations for which their technical skills are needed. These organizations may include: local, state, and federal governments, private and public corporations, and education. Chemical engineers are involved in process and plant operation, technical services groups, research and development laboratories, plant design groups, occupational and safety programs, technical sales, technical training, and technical management. Graduate education can lead to careers in the medical sciences, chemical engineering, and other engineering and scientific disciplines as well as business and law.
