Polymer Products
Polymers are among some of the most useful and valuable products of the chemical industry. In general, polymer products are classified as plastics and resin products or as rubber products. A plastic material is defined as a solid, high-molecular-weight, polymerized organic substance and typically involves liquid-phase manufacturing or processing of the material [2]. Plastic and resin…

Fertilizer Products
Fertilizer industries are vital components of a nation’s economy; however, the significance of fertilizer products cannot be measured merely by the economic value they add. The sustainability of food production is critically dependent on the availability of fertilizers. In that sense, fertilizer production is the most important endeavor of the chemical industry. Fertilizer products utilize the…

Basic Organic Chemicals and Petrochemicals
Almost all of the organic chemicals produced by the chemical industry are obtained from seven basic chemicals: methane, ethylene, propylene, butadiene, benzene, toluene, and xylene. Methane is the primary constituent of natural gas. Although some minor sources are available for the rest of the basic organic chemicals, they are invariably derived from petroleum, and chemicals…

Industrial Gases
Except for chlorine, which is considered a basic inorganic chemical, other industrially significant gases have their own distinct category. The most important of industrial gases are oxygen, nitrogen, hydrogen, and carbon dioxide. Oxygen and nitrogen are obtained from air primarily through cryogenic liquefaction and distillation. The use of nitrogen (and of hydrogen) is dominated by ammonia…

Basic Inorganic Chemicals
Chemicals produced in bulk quantities and used primarily in subsequent industrial processes are termed as basic chemicals. Basic inorganic chemicals are, as the name indicates, non-carbon-based compounds, though carbon dioxide and inorganic carbonates are included under this category. Nearly 40% of the top 50 chemicals are basic inorganic chemicals [1]. Typically, seven of the top 10…

The Chemical Industry
The chemical industry manufactures a vast number of chemicals to serve the needs of the society. Chemicals sharing common characteristics are grouped together and classified under the same NAICS codes for analyzing their economic impact. The chemical products are broadly classified into seven categories: Basic Inorganic Chemicals, Industrial Gases, Basic Organic Chemicals and Petrochemicals, Fertilizer…

Classification of Industries
Before venturing into the nature of chemical and allied industries and understanding its role, it is instructive to look at the classification system used by governments to analyze and track the various sectors of the nation’s economy. The U.S. government developed a standardized system in the 1930s called the Standard Industrial Classification (SIC) system for classifying…
