However, in the "process (engineering)" sense, the term "chemical process" is used extensively. The rest of the article will cover the engineering type of chemical processes. Although this type of chemical process may sometimes involve only one step, often multiple steps, referred to as unit operations, are involved.

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 ...
Chemical synthesis (chemical combination) is the artificial execution of chemical reactions to obtain one or several products. [1] This occurs by physical and chemical manipulations usually involving one or more reactions. In modern laboratory uses, the process is reproducible and reliable.
A chemical reaction is a process that leads to the chemical transformation of one set of chemical substances to another. [1] When chemical reactions occur, the atoms are rearranged and the reaction is accompanied by an energy change as new products are generated.
Chemical kinetics – study of rates of chemical processes. Chemical physics – investigates physicochemical phenomena using techniques from atomic and molecular physics and condensed matter physics; it is the branch of physics that studies chemical processes.
A chemical plant is an industrial process plant that manufactures (or otherwise processes) chemicals, usually on a large scale. [1] The general objective of a chemical plant is to create new material wealth via the chemical or biological transformation and or separation of materials. [2]
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.
