The plants and processes in chemical process industries possess the following major characteristics: • Large production capacity: The average production capacities of plants engaged in the manufacture of bulk chemicals such as sulfuric acid, ammonia, and ethylene can easily reach into thousands of tons per day (tpd). The largest sulfuric acid plant in the United States has…

The United States occupies the top position among chemical manufacturers, accounting for nearly one-fifth of the chemicals produced worldwide [5]. The total value of the chemical goods produced in the United States in 2010 was $701 billion, and the chemical manufacturing sector contributed the largest fraction to the U.S. exports. Table 2.4 shows the 2010 production volumes…

Chemical engineers perform critical roles in many other industries, including those listed in Table 2.1. These industries and their products are described in the following subsections. 2.3.1 Paper Products Industries classified under NAICS code 322 are involved in the manufacture of paper products. These industries include pulp mills that convert wood and biomass to pulp and paper…

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…

The Chemical Industry: Chemical engineers have traditionally found employment in the chemical and allied industries, and these industries continue to be the major employers of chemical engineers. The chemical and allied industries comprise one of the most important manufacturing sectors of a nation’s economy. However, despite their significance, these industries are not well understood by…
