Chemical engineers design, construct and operate process plants (fractionating columns pictured)Chemical engineering is a branch of engineering that uses principles of chemistry, physics, mathematics, biology, and economics to efficiently use, produce, transform, and transport chemicals, materials, and energy. A chemical engineer designs large-scale processes that convert chemicals, raw materials, living cells, microorganisms, and energy into useful forms and products.Chemical engineers are involved in many aspects of plant design and operation, including safety and hazard assessments, process design and analysis, control engineering, chemical reaction engineering, biological engineering, construction specification, and operating instructions. Chemical engineering degree is directly linked with all the majors of various engineering disciplines.

化學(xué)工程師設(shè)計(jì)、建造和操作工藝裝置（如圖所示的分餾塔）化學(xué)工程是工程學(xué)的一個(gè)分支，它利用化學(xué)、物理、數(shù)學(xué)、生物學(xué)和經(jīng)濟(jì)學(xué)的原理來(lái)有效地使用、生產(chǎn)、轉(zhuǎn)化和運(yùn)輸化學(xué)品、材料和能源。一位化學(xué)工程師設(shè)計(jì)了將化學(xué)物質(zhì)、原材料、活細(xì)胞、微生物和能量轉(zhuǎn)化為有用形式和產(chǎn)品的大規(guī)模工藝。化學(xué)工程師參與了工廠設(shè)計(jì)和運(yùn)行的許多方面，包括安全和危害評(píng)估、工藝設(shè)計(jì)和分析、控制工程、化學(xué)反應(yīng)工程、生物工程、施工規(guī)范和操作說(shuō)明。化學(xué)工程學(xué)位與各工程專業(yè)各專業(yè)直接掛鉤。
