Technical Chemistry methods and more
The Chemical Engineering is concerned generally with production processes and methods for producing a wide range of products. The methods are always areas for economic and environmental considerations designed and optimized it.
Here, the procedures in terms of the energy and mass quantities of balance sheet and crystallized appropriate steps that improve the balance sheets. It is, different from the pure chemistry, the processes and reactions rather on the larger scale of industrial. Core disciplines of technical chemistry, the chemical reaction engineering, thermodynamics and process customers. The Technical chemistry is therefore in close association with the process technology
The best known method is the synthesis of ammonia by Haber and Bosch. Using this so-called Haber-Bosch process ammonia can be produced in large quantities from the basic elements nitrogen and hydrogen.
It is named after their discoverers, Fritz Haber and Carl Bosch. It is still one of the most important process, since ammonia is used in large quantities for the production of fertilizer and nitric acid. The compound is also happy to do as a refrigerant or flue gas cleaning in use.
Basic operations and task of the technical chemistry
Besides the chemical reaction itself, for the process flow observed a few basic operations. These basic operations are the necessary physical processes during the process and act as the elementary steps of driving a process.First is to address the basic mechanical operations. This generally includes processes for material crushing, Stoffföderung or separation.
An example of the previous Währe chipping a reactant to increase the reaction surface and hence to accelerate the reaction. In the sediment, which mainly refers to its use in wastewater treatment plants, substances are separated according to their density differences. The solids largely separated water can then be further transported to the next step.
Using thermal unit operations such as rectification, absorption and adsorption can also combine or separate materials. In an absorption scrubber sulfur is absorbed from the exhaust gas and thus removed the flue gas. Rektifikationskollonen work like a normal distillation system only in several successive steps.
The chemical engineering is found in numerous products simply return to our daily life. Plastics, pesticides, dyes, or medical products are all derived from the industrial chemistry. Here, the engineers have to model is always the object, the method according to the highest economic and environmental requirements.
