What relates to the chemical-technological factors, ensuring the fulfillment of the scientific organization of the modern chemical industry products?

1. With a view to accelerating the process of any chemical production requires maximizing the surface of the reactants. Therefore process usually begins with a special pre-treatment of raw materials: mechanical comminution (crushing), enrichment and purification. Examples of typical grinding devices used in everyday life, are coffee grinder, blender or meat grinder. Selecting the best available technology (BAT), which is the most technically advanced methods of preparation of raw materials and its pre-treatment, refer to the common organization of the scientific basis of modern chemical industries.

2. Many chemical reactions are exothermic, that is, proceed with the heat. On the other hand, to initiate many reactions require heating to certain temperatures. For this purpose, in the production of various heat exchangers are used, which allow to recycle heat of chemical reactions. The role of the coolant water is often performs. An example of the use of heat transfer is a samovar in which the combustion heat is used to heat vody.Ispolzovanie heat of chemical reactions in the technological cycle is called the heat exchange and relates to the technological principles of the organization of chemical production.

3. In order to achieve the most intimate contact of the reactants in the chemical industry, in addition to the grinding of these materials are also required movement in relation to each other. For this purpose, the mass transfer principle and its variants - countercurrent flow of reactants in one direction and mixing, thus achieving maximum uniformity and completeness of the process of use of the reactants. Agitation is a common example of mass transfer, accelerating the process of natural diffusion.

4. Most of the chemical production processes - reversible. In order to accelerate the chemical reaction and increase the yield, production conditions are selected in the optimum concentration of reactants, temperatures and pressures (for the gaseous substances). Very often, to change the direction of the reaction using catalysts (recall that the use of a catalyst has no effect on the shift of chemical equilibrium, as it increases the rate of both the forward and reverse processes). 5. An important technological factor is the continuity of the chemical processes of the production process, ensuring higher productivity. Therefore, the use of manual operations, for which you want to stop the process, is undesirable. In order to ensure continuity of the process using automatic control system (AMS) and the mechanization of the process.
