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.
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 general the classification of chemical industry products by the Kline matrix is related to the chemicals' worldwide production (measured for example in tons/year) and to their value added. [6] Following this classification, the chemical industry products are divided into four categories: true commodity: high production and high value added

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 ).
Note: The 'topics' are a selection of related articles provided by Wiley Online Library. The number (#) indicates that, for example, 15 articles relate to the main branch of agrochemicals . The numbers do not exactly sum up to the total number of articles (1,050), but its sole purpose is for organizing and categorizing the large number of ...
Process analytical chemistry (PAC) is the application of analytical chemistry with specialized techniques, algorithms, and sampling equipment for solving problems related to chemical processes. It is a specialized form of analytical chemistry used for process manufacturing similar to process analytical technology (PAT) used in the ...
An industrial process alters materials or substances. Some processes make the production of a rare material vastly cheaper, thus changing it into a commodity ; i.e. the process makes it economically feasible for society to use the material on a large scale.
