4 Importance of Chemistry for Engineers and Its Application in Industries

Chemistry is a branch of science that deals with the properties and physical and chemical characteristics of matter or matter and its interaction with energy. There are many differences that can be seen when comparing basic chemistry and modern chemistry. Basic chemistry comes from ancient times, namely in the days of scientists named alchemists.

Importance of Chemistry for Engineers and Its Application in Industries

The basic chemistry explains all the fundamentals of the subject that concludes after the series of experiments. While modern chemistry that dominated in the 17th century laid the systematic steps in gaining knowledge. (Read Development of Atomic Theory)

Then what are the importances of chemistry for engineers and its applications? Here they are :

  1. Chemistry for Mechanical Engineer

Mechanical Engineering is an engineering / engineering branch that studies its energy and energy sources and applications from the principles of physics to the analysis, design, manufacture and maintenance of a mechanical system.

Mechanical Engineering is one field of engineering science that can provide great opportunities to realize the machine industry in terms of maintenance and repair, design / design, manufacture / production and environmental systems in the future. This profession is highly supported by high intellectual, creative and innovative power.

What’s Learned in Mechanical Engineering?

Students of Mechanical Engineering besides must be able to master the basic of the exact science (mathematics, physics, chemistry), they also have to understand various concepts including mechanics, kinematics, thermodynamics and energy.

The field of study in Mechanical Engineering deals a lot with early movers, such as steam turbines, combustion engines, machine tools, pumps and compressors, cooling and heating, and certain chemical appliances. In addition, in Mechanical Engineering also studied the physical properties and phenomena that occur in a material. This includes the properties of the material in support of tension, pressure, or twist. (Read Applications of Chemistry in Daily Life)

All engineering science requires basic science knowledge including including chemistry to solve engineering problems. Chemistry is the study of “matter” along with its properties, structure, and characteristics.

For example in chemistry lessons we learn about aluminium matter and its properties, structure, and characteristics.
in aerodynamics engineering (majors of aircraft manufacture) aluminum is the material for the manufacture of airframe. Of course knowledge about aluminum is in need.

  1. Chemistry for Chemical Engineer

Here’s the importance of Chemistry for engineers and its application in industries. Chemical Engineering is a branch of Engineering that applies natural science (Chemistry and Physics) and life sciences (Biology, Microbiology and Biochemistry) together with Mathematics and Economics to produce, transform, and use chemicals, materials , and energy to become products with higher economic value.

Chemical engineering is a branch of engineering or engineering that studies the processing of raw materials into more useful items, either in the form of finished goods or semi-finished goods. Chemical engineering is applied primarily in the design and maintenance of chemical processes, both on a small scale and on a large scale such as a factory. 

Chemical engineering engineers whose work is responsible for the design and maintenance of chemical processes at the plant scale are known as “process engineers”. In addition, modern chemical engineering engineers also conduct research aimed at discovering new materials and techniques, which are sometimes also associated with other disciplines, such as nanotechnology, fuel cells, and biomedical engineering.

In chemical engineering, there are 2 large subgroups that include:

1.) Design, build, and operate the plant / plant and the chemical processes in it.
2.) Develop a new substance or development of an earlier substance on products ranging from food and beverages to cosmetics, cleansers, and medicines.

  1. Chemistry for Biotechnology Engineer

At this time, biotechnology is growing very rapidly, especially in developed countries. This progress is characterized by the discovery of various technologies such as genetic engineering, tissue culture, recombinant DNA, stem cell proliferation, cloning, and others. This technology enables us to get the healing of chronic and genetic diseases that can not be cured, such as cancer or AIDS.

Research in stem cell development also allows stroke patients or other diseases that result in loss or damage to body tissues can heal as before. In the field of food, using genetic engineering technology, tissue culture and recombinant DNA, can produce plants with superior properties and products because they contain more nutrients than ordinary plants, and also more resistant to pests and environmental pressures. Application of biotechnology at this time can also be found in the environmental conservation of the pollen.

For example, on the decomposition of petroleum spilled into the sea by bacteria, and the decomposition of toxic substances (toxins) in rivers or seas using new types of bacteria. In order to deal with those substances a biotechnology engineer must master chemistry.

  1. Chemistry for Industrial Engineer

There are many importance of Chemistry for engineers and its application in industries. Chemistry is often referred to as central science because in any discipline it is always related to chemistry. An expert who performs experiments on chemistry is said to be a scientist, where the scientist is doing research on material changes and the changes that accompany it.

Chemistry is basic for industrial engineering. An example of the implementation of chemistry by the Industry is the use of fertilizers in the field of agriculture both chemical fertilizers and non-chemical fertilizers, although different both types of fertilizers are using the concept of chemistry. The use of fertilizer is really a tremendous breakthrough because it can increase crop yields, protect crops from pests and diseases and improve the quality of the harvest. In case of making fertilizer in large amount for industrial interest, an industrial engineer must master chemistry first.

Another example of the application of chemistry in industry is The role of chemistry plays a role in the process of crystallization of sugar from sugar cane, for example the regulation of crystallization kinetics for crystal size setting, helps bleaching process of sugar (bleaching). Included in this case chemistry also plays a role for the application of liquid waste processing from the processing of sugar, for processing alcohol from the resulting drip result, and so forth.

In the other hand, the machines in the industry require a good metal with certain properties that match the conditions and materials used. Such as cement, wood, paint, concrete, etc. produced through research based on chemistry. The synthetic fabric you use is also the result of the application of Chemistry.

Various product materials produced from petrochemical products today are widely found. Petrochemicals are materials or products produced from oil and gas. These petrochemical materials can be classified into plastics, synthetic fibers, synthetic rubbers, pesticides, detergents, solvents, fertilizers, various drugs or vitamins.

Example on petrochemical industry:

Petrochemical Basic Materials

There are three basic materials used in the petrochemical industry, namely olefins, aromatics, and synthesis gas (syn-gas). To obtain petrochemical products carried out with three stages, namely:

  1. Converting oil and gas into petrochemical base materials.
  2. Turning the basic ingredients into intermediate products.
  3. Turning the intermediate product into an end product.

That’s all the importance of chemistry to engineers and its application. Hope this article is useful. Thanks.
