what is chemical engineering

She has a B.A. The…, Roberto Crispulo Goizueta, Cuban-born American businessman who served as chairman and CEO of the Coca-Cola Company. By the 1970s, legislation and monitoring agencies were instituted in various countries, such as France, Germany, and the United States. The term chemical engineer was in general use by about 1900. Chemical engineering sits at the nexus between science and technology. Before a chemical engineer brings these materials to full scale production, there is plenty of experimentation in the laboratory. Chemical engineering is also one of the oldest and core fields of engineering thats has brought new inventions and ease for mankind. her specialty when contributing to wiseGEEK. Premium Membership is now 50% off! In the same way that a complex plant can be divided into basic unit operations, so chemical reactions involved in the process industries can be classified into certain groups, or unit processes (e.g., polymerizations, esterifications, and nitrations), having common characteristics. The work of chemical engineers can range from the utilization of nanotechnology and nanomaterials in the laboratory to large-scale industrial processes that convert chemicals, raw materials, living cells, microorganisms, and energy into useful forms and products. Just a few examples include clothing (fabric and dyes), paint, paper, plastics, soaps, cosmetics, food products, medications, and semiconductors. It is the branch of engineering concerned with the design, construction, and operation of machines and plants that perform chemical reactions to solve practical problems or make useful products. Chemical engineering is as old as the process industries. Chemical engineering is useful in the development of products, such as metals, detergents, plastics, and pharmaceuticals, from chemicals. Chemical engineers continue to invent and optimize methods for cleaner and more efficient energy usage. Chemical engineers are involved in many aspects of plant design and operation, including safety and hazard assessments, process design and analysis, modeling, control engineering, chemical reaction engineering, nuclear engineering, biological engineering, construction specification, and operating instructions. New compounds may be discovered by chemists; however, without a chemical engineer engaging her skills to quantify, test, and produce it, the new compound may never become a final product. You may know that elements make up the air we breathe and the water we drink, but do you know more about them? Notify me of follow-up comments by email. [25] In response, the IChemE required safety to be part of every degree course that it accredited after 1982. [35], Chemical engineers may be involved in industry or university research where they are tasked with designing and performing experiments to create better and safer methods for production, pollution control, and resource conservation. After plant construction, chemical engineering project managers may be involved in equipment upgrades, process changes, troubleshooting, and daily operations in either full-time or consulting roles. These constraints dictate a plant's choice of process, materials, and equipment. Chemical engineering fields. Learn more about Chemical Engineering is concerned with the design, construction and operation of processes that convert raw materials into products with a higher economic value. Take a look at what exactly chemical engineering is, what chemical engineers do, and how to become a chemical engineer. They devise ways to make products from raw materials and ways to convert one material into another useful form. Find out the answers in this quiz. Editor of. [12] By the early 1920s, unit operations became an important aspect of chemical engineering at MIT and other US universities, as well as at Imperial College London. [citation needed] These incidents, along with other incidents, affected the reputation of the trade as industrial safety and environmental protection were given more focus. Black Friday Sale! In the second half of the 20th century, considerable numbers of chemical engineers have been involved in space exploration, from the design of fuel cells to the manufacture of propellants. It starts in the lab, much like science, yet progresses through the design and implementation of a full-scale process, its maintenance, and methods of testing and improving it. Throughout its development as an independent discipline, chemical engineering has been directed toward solving problems of designing and operating large plants for continuous production. The pharmaceuticals industry presents chemical engineering problems, the solutions of which have been essential to the availability of modern drugs. In modifying the product or process, they want to ensure that it is better than before, without posing safety issues, creating undue waste, or spending too much money or time. What Skills Does a Chemical Engineer Need? [17] Along with other novel concepts, such as process systems engineering (PSE), a "second paradigm" was defined. Mathematics is a basic tool in optimization and modeling. Chemical engineers are encouraged to obtain a license, but it is not always required (as it is for many other engineering professions). Chemical engineers use chemistry, math, physics, and sometimes biology to improve the quality of life by inventing, optimizing, and economizing new technologies and products.Chemical engineering is the analysis or design of chemical processes to effectively convert materials into … Armstrong's course failed simply because its graduates were not especially attractive to employers. Variations due to different parameters, such as energy source used, plant layout, and environmental factors, can be predicted accurately and quickly so that the best combination can be chosen. Chemical engineering is the analysis or design of chemical processes to effectively convert materials into more useful materials or into energy.
