Chemical processes


It is known as process yet cycle formed by stages that happen and cause a certain change of state. The processes involve the passage of time or, sometimes, a symbolic advance.

Chemical , on the other hand, is something linked to the chemistry . This notion (chemistry) refers to a science dedicated to the analysis of the composition, characteristics and modifications of the matter .

The chemical processes are operations that derive in the modification of a substance , either from a change of state , of composition or other conditions. These processes involve the development of chemical reactions .

A chemical process can also lead physical reactions . If the initial matter is compared with the result at the end of the process, various types of changes will be noticed. Chemical processes can develop naturally or from manipulation of the man .

It is possible to find chemical processes in all areas. Scientists even argue that the crush it is nothing more than a chemical process caused by endorphins as the phenylethylamine , the dopamine and the norepinephrine . The biological action of this class of hormones is due to the need to establish links that result in reproduction and, therefore, in the subsistence of species .

The production of came It also develops from chemical processes. The action of yeasts on the wort drives the fermentation of sugars: glucose is transformed into alcohol and carbon dioxide. Then other reactions, such as sulphite, occur until the wine is obtained with the properties that reach the tables.

There is a close relationship between chemical processes and the industry ; in fact, they are considered part of the so-called industrial processes, which consist of a series of physical and chemical transformations that are carried out in order to produce a final product, different from the initial one. Throughout this process, several stages are carried out, and it can be found in many areas, with very different objectives, such as the following:

* metal purification;
* scientific investigation;
* plastics manufacturing;
* food processing;
* cleaning of waters ;
* drug manufacturing;
* development of construction materials.

Although the first image that usually comes to mind when we think of chemistry is a test tube, many of the chemical processes are carried out in reactors, vessels or equipment in which they are carried out chemical reactions in a controlled manner , taking into account factors such as pressure, temperature and the number of reactants, among many others.

Sometimes the reactors are biological, that is, living beings that are involved in chemical processes to perform different tasks. This can be seen, for example, in copper leaching and water cleaning contamination .

Types of chemical processes

* Metallurgical process

Metallurgy is the technology and science used to separate metals from their ores (a type of mineral). The metallurgical process groups together certain chemical processes, such as electrochemical reduction, which serves to achieve the purity of a metal from the reduction of its components.

* Pyrometallurgy

This series of chemical processes is based on the use of high temperatures for the modification of the mineral and its reduction to free metal.

* Electrometallurgy

A group of processes to reduce metal ores or refine metals, based on electrolysis (the use of current electrical to decompose a substance in solution).

* Food manufacturing

In this case, many chemical processes with substances such as dyes, preservatives and flavorings are used to obtain various objectives, ranging from preservation to flavor enhancement.
