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.
In 2012, the chemical sector accounted for 12% of the EU manufacturing industry's added value. Europe remains the world's biggest chemical trading region with 43% of the world's exports and 37% of the world's imports, although the latest data shows that Asia is catching up with 34% of the exports and 37% of imports.

As the main energy-consuming and greenhouse-gas–emitting stage of cement manufacture, improvement of kiln efficiency has been the central concern of cement manufacturing technology. Emissions from cement kilns are a major source of greenhouse gas emissions , accounting for around 2.5% of non-natural carbon emissions worldwide.
This is not always true for reversible reactions. For most chemical reactions of industrial interest, it is impossible for the reaction to proceed to 100% completion. The rate of reaction decreases as the reactants are consumed until the point where the system reaches dynamic equilibrium (no net reaction, or change in chemical species occurs).
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]
In the chemical industry and industrial research, catalysis play an important role. Different catalysts are in constant development to fulfil economic, political and environmental demands. [3] When using a catalyst, it is possible to replace a polluting chemical reaction with a more environmentally friendly alternative.
The Solvay Process as an example of a cyclic process in chemical industry (green = reactants, black = intermediates, red = products) The Solvay process results in soda ash (predominantly sodium carbonate (Na 2 CO 3 )) from brine (as a source of sodium chloride (NaCl)) and from limestone (as a source of calcium carbonate (CaCO 3 )).
