Certain chemical process yield important basic materials for society, e.g., (cement, steel, aluminum, and fertilizer).However, these chemical reactions contribute to climate change by emitting carbon dioxide, a greenhouse gas, through chemical reactions, as well as through the combustion of fossil fuels to generate the high temperatures needed to reach the activation energies of the chemical ...
In an "engineering" sense, a chemical process is a method intended to be used in manufacturing or on an industrial scale (see Industrial process) to change the composition of chemical(s) or material(s), usually using technology similar or related to that used in chemical plants or the chemical industry.
Chemical engineers design, construct, and operate process plants, such as these fractionating columns. Chemical engineering is an engineering field which deals with the study of the operation and design of chemical plants as well as methods of improving production. Chemical engineers develop economical commercial processes to convert raw ...
Industrial separation processes are technical procedures which are used in industry to separate a product from impurities or other products. The original mixture may either be a natural resource (like ore , oil or sugar cane) or the product of a chemical reaction (like a drug or an organic solvent ).
The roots of the industrial engineering profession date back to the Industrial Revolution.The technologies that helped mechanize traditional manual operations in the textile industry including the Flying shuttle, the Spinning jenny, and perhaps most importantly the Steam engine generated Economies of scale that made Mass production in centralized locations attractive for the first time.
In 2012 the data from the European Chemical Industry Council shows that five European countries account for 71% of the EU's chemicals sales. These are Germany, France, the United Kingdom, Italy and the Netherlands. [22] The chemical industry has seen growth in China, India, Korea, the Middle East, South East Asia, Nigeria and Brazil.
A "pure" unit operation is a physical transport process, while a mixed chemical/physical process requires modeling both the physical transport, such as diffusion, and the chemical reaction. This is usually necessary for designing catalytic reactions , and is considered a separate discipline, termed chemical reaction engineering .
