UCD students brew coffee to learn basics of chemical engineering – Students begin their lab studies by dismantling a coffeemaker to figure out how it works, then experiment with different techniques in roasting and brewing, measuring the chemical and physical changes involved. The course will end with a tasting competition: the object being to make the best-tasting cup of coffee from the same basic ingredients while using the least energy.

Chemical engineers apply the principles of chemistry to solve design and supervise facilities for the production and use of chemicals and biochemicals. They must be aware of all aspects of chemicals manufacturing and how the manufacturing process affects the environment and the safety of the workers and consumers. Examples include desalinization plants and semiconductor processing equipment. Examples of new human-related challenges are in designing and building equipment for large-scale production of artificial skin and bacteria-created antibiotics. They typically work for organizations such as Dow, DuPont, Motorola, and Monsanto.

Chemical engineering – applied chemistry. 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 engineers have helped develop atomic science, polymers, paper, dyes, drugs, plastics, fertilizers, foods, petrochemicals…

• Chemical engineers use chemistry, physics, and math along with engineering tools to solve problems relating to the production and use of chemicals. This includes things like refining gasoline and other fuels from petroleum, purifying of drinking water, treating waste, recovering raw materials, and producing and processing food. They can work in chemical manufacturing, electronics, pollution control, even medicine and food processing.
• Chemical engineering – applies the physical sciences (e.g., chemistry and physics) and/or life sciences (e.g., biology, microbiology and biochemistry) together with mathematics and economics to processes that convert raw materials or chemicals into more useful or valuable forms. In addition, modern chemical engineers are also concerned with pioneering valuable materials and related techniques – which are often essential to related fields such as nanotechnology, fuel cells and biomedical engineering.
• Chemical engineers apply the principles of chemistry, biology, and physics to solve problems. These problems involve the production or use of chemicals, fuel, drugs, food, and many other products. They design processes and equipment for large-scale safe and sustainable manufacturing, plan and test methods of manufacturing products and treating byproducts, and supervise production.

Chemistry through History

• Matches – John Walker invented a way to make fire more portable. During experiments, Walker (a chemist) inadvertently created a paste that would burst into flames when scratched against a rough surface. He started selling matches made from cardboard sticks in 1824. Walker never patented his breakthrough product, and Sir Isaac Holden (who took over the work that Walker left unfinished) eventually gained fame for the invention.

Examples of Chemical Reactions in Everyday Life – the process, where chemical substances react with each other, which leads to their conversion into other different forms. The initial substances used the reaction are reactants. The final substances formed after the reaction are known a products. In general, the chemical properties of the reactants and products are different from each other. Spontaneous reaction occurs on its own. Non-spontaneous reaction requires energy for activation.

• photosynthesis
• rusting and burning

Meet some Chemical Engineers

• Shauntel designs household products we use every day
• Thomas – Core technology leader for food mixing applications with in a group of Chemical Engineers that work with common chemical engineering unit operations – liquid mixing, heat transfer, heat exchanges.
• Chemical Engineering – pharmaceutical companies such as Novartis and Pfizer need chemical engineers to create new medicines. Food manufacturers like General Mills rely on chemical engineers to come up with new food products and packaging. Chemical engineers also work at chemical companies like DuPont, and Dow Chemical Co.; at energy firms such as Chevron and ConocoPhillips; and at all sorts of manufacturing companies like 3M and Procter & Gamble.

That’s engineering
