毕业于利哈伊（Lehigh）的化学工程师在化学过程工业中继续发挥重要作用，例如研究，开发，设计，工厂建设，工厂运营和管理，企业计划，技术销售和市场分析。他们将原材料转换为多种产品，并在石油和石化，橡胶和聚合物，金属，工业和精细化工以及工业气体等行业中工作。他们承担化学家的小规模工作，并将其应用于大规模过程和产品。此外，化学工程师是生物工程和生物技术许多令人兴奋的领域的推动力，包括制药和生物制药研发，细胞生物工程，诊断，药物输送以及从香水到蜡笔再到牙膏的食品和消费品的大规模加工。
Chemical engineers who graduate from Lehigh go on to play important roles in the chemical process industry in areas such as research, development, design, plant construction, plant operation and management, corporate planning, technical sales and market analysis. They convert raw materials into a variety of products and work in industries that specialize in petroleum and petrochemicals, rubbers and polymers, metals, industrial and fine chemicals and industrial gases. They take the small-scale work of the chemist and apply it to large-scale processes and products. Additionally, chemical engineers are the driving force in many exciting areas of bioengineering and biotechnology, including pharmaceutical and biopharmaceutical R&D, cellular bioengineering, diagnostics, drug delivery and the large-scale processing of food and consumer products from perfume to crayons to toothpaste.
