What is Chemical Engineering? Topics Covered: 1. What is mean by Engineering? 2. Introduction to Chemical Engineering 3. Chemical Engineering in day to day life 4. Sub-branches of chemical engineering.
What is mean by Engineering? The term engineering is derived from two Latin words ingenium and ingeniare. Ingenium means talent or cleverness and ingeniare means to design or devise.(Devise means to invent by careful thought). If we combine the meaning of these two words, we can say that engineering means, to create something by using relevant skills to fulfill a particular need of society. In technical terms, Engineering is the use of scientific principles to design and build machines, structures, and other items, including bridges, tunnels, roads, vehicles, buildings etc. E.g. Chemical engineering, mechanical engineering, etc. Main branches of engineering: 1. Chemical Engineering 2. Civil Engineering 3. Computer Engineering 4. Mechanical Engineering 5. Electrical Engineering 6. Interdisciplinary Engineering (e.g. Software engineering, Agricultural Engineering etc.) (Here relevant concepts of two or more main engineering branches are combinedly used)
Introduction to Chemical Engineering Definition: Chemical engineering is a branch of engineering that uses principles of chemistry, physics, mathematics, biology, and economics to efficiently use, produce, design, transport and transform energy and materials. A chemical engineer is persons who produces necessary chemicals, materials and other products in large scale. The main difference between chemist and chemical engineer is that, chemist mostly works on laboratory scale and chemical engineer works on industrial scale. e.g. production of 150 tonnes of nitric acid per day. Duties of chemical engineer: 1. Chemical Engineers design chemical plant equipment and devise processes for manufacturing chemicals and products, such as gasoline, synthetic rubber, plastics, detergents, cement, paper, and pulp etc. 2. Develop processes to separate components of liquids or gases or generate electrical currents, using controlled chemical processes. 3. Troubleshoot problems with chemical manufacturing processes. 4. Evaluate chemical equipment and processes to identify ways to optimize performance or to ensure compliance with safety and environmental regulations. 5. Conduct research to develop new and improved chemical manufacturing processes. 6. Perform laboratory studies of steps in manufacture of new products and test proposed processes in small-scale operation, such as a pilot plant. 7. Develop safety procedures to be employed by workers operating equipment or working in close proximity to ongoing chemical reactions.
Chemical Engineering in Day to Day life 1. We use fermentation on daily basis for production of curd as well as we use heating as food preservation techniques. 2. We use mechanical operations like agitation for producing butter and butter-milk 3. We use concepts of heat transfer and thermodynamics in the devices like pressure cooker, refrigerators, heaters , etc. 4. We use concepts like capillary action and evaporative cooling in earthen pot. Movement of water from inner surface area of pot to the outer surface area of pot is done by capillary action. This water evaporates and for that energy of water present inside the pot is used. Hence water inside the pot is cool. It is called as evaporative cooling. 5. We use process know as leaching for making of tea.
Sub-branches of Chemical Engineering Biochemical Engineering/ Bioprocess Engineering It mainly deals with the design, construction, and advancement of unit processes that involve biological organisms or organic molecules and has various applications in areas of interest such as biofuels, food, pharmaceuticals, biotechnology, and water treatment processes Food Engineering: Food engineering is a multidisciplinary field which combines microbiology, applied physical sciences, chemistry and engineering for food and related industries. Polymer Engineering: Polymer engineering is generally an engineering field that designs, analyses, and modifies polymer materials. Pulp and Paper industry: The pulp and paper industry comprises companies that use wood as raw material and produce pulp, paper, paperboard and other cellulose-based products. Dyestuff Technology: Dyestuff and Intermediate. Technology is a combination of chemical engineering and organic chemistry. Petrochemical Engineering: Petrochemical engineering is a branch of Chemical Engineering which deals with operations involved in refining petroleum or crude oil by the use of advanced technology.
