化学工程利用化学，数学，生物学和物理学来提供一种综合的方法，以理解从分子到全局规模的过程中发生的变化，并创建可以改变化学或物理组成，能量含量，结构或物理的方法状态，即行动中的数学和科学。该主题还涉及将知识应用于处理化学及相关产品的工厂的设计，开发和运营。它与机械，电气和土木工程，化学，材料科学和生物学等领域接壤和重叠。
Chemical Engineering is concerned with the design and operation of processes which convert materials and energy into the higher value products we use every day. It understands the processes which occur at the small scale and relates these to the larger scale production of, for example: pharmaceuticals, food stuffs, energy, polymers, lubricants, fuels, semiconductors, batteries, paints and coatings. The main tools of the Chemical Engineer are the applied sciences, engineering, technology, finance and management in that as a Chemical Engineer you become proficient in not only identifying how to convert materials into functional products but also in how to construct, operate and manage facilities so that they are economical, ethical and sustainable. It borders and overlaps with other engineering disciplines including mechanical, electrical and civil engineering as well as business studies and entrepreneurship.<br>Four-year MEng and five-year MEng (with a Year in Industry) degrees are available for high-calibre students with the ability and aspiration to study Chemical Engineering at the highest levels. BEng students with excellent performance may transfer to the MEng up to the end of Stage 3.
