Definition von chemical engineering im Englisch Englisch wörterbuch
The branch of engineering that deals with the design, construction and operation of industrial process plants, and the physical, chemical and biological processes to create substances or energy in a useful and economic form
the activity of applying chemistry to the solution of practical problems the branch of engineering that is concerned with the design and construction and operation of the plants and machinery used in industrial chemical processes
Chemical engineering is the designing and constructing of machines that are needed for industrial chemical processes. The branch of engineering that deals with the technology of large-scale chemical production and the manufacture of products through chemical processes.chemical engineer n. the study of machines used in industrial chemical processes engineer. Academic discipline and industrial activity concerned with developing processes and designing and operating plants to change materials' physical or chemical states. With roots in the inorganic and coal-based chemical industries of western Europe and the oil-refining industry in North America, it was spurred by the need to supply chemicals and products during the two World Wars. The field includes research, design, construction, operation, sales, and management activities. Chemical engineers must master chemistry (including the nature of chemical reactions, the effects of temperature and pressure on equilibrium, and the effects of catalysts on reaction rates), physics, and mathematics. The engineering aspect, involving fluid flow (see deformation and flow) and heat and mass transfer, is broken down into "unit operations," including vaporization, distillation, absorption, filtration, extraction, crystallization, agitation and mixing, drying, and size reduction; each is described mathematically, and its principles apply to any material. Chemical engineers work not only in the chemical and oil industries but also in such processing industries as foods, paper, textiles, plastics, nuclear, and biotechnology
