Acetyl Chemicals from Coal Gasification

Eastman Chemical Company | Kingsport, Tennessee

Prompted by the oil embargoes of the 1970s, Eastman Chemical Company opened the first U.S. plant to make acetyl chemicals—important building blocks in the production of a wide range of consumer products such as plastics, textile fibers and photographic film—from coal, a secure, domestic resource, rather than foreign petroleum. By substituting locally available, high-sulfur coal, Eastman’s plant conserved petroleum previously required for the production of these high-volume chemicals. Learn more.

Charles Herty and the Savannah Pulp and Paper Laboratory

Herty Advanced Materials Development Center | Savannah, Georgia

When Georgia chemist Charles Holmes Herty found a way to make quality paper from pine trees in 1932, he also founded an industry that brought much-needed jobs to the depression-crippled south. Herty wrote a new chapter in the ancient craft inspired by insects who built paper nests while dinosaurs still roamed the earth. At its root, however, the papermaking process remained the same: the bonding of cellulose, a polymer whose long chains support plant cell walls. Learn more.

Development of the Pennsylvania Oil Industry

Drake Well Museum | Titusville, Pennsylvania
U.S. Steel Tower | Pittsburgh, Pennsylvania

In Pittsburgh in the 1850s Samuel Kier, who originally marketed petroleum as a medicine, built the first still to refine oil into kerosene to burn in lamps. But the usefulness of using petroleum to light homes and businesses was limited by the difficulty of getting it out of the ground. That changed on August 27, 1859, when Colonel Edwin Drake’s struck oil at his newly drilled well in Titusville, Pennsylvania. Within three years Pennsylvania was producing three million barrels of oil a year. Learn more.

Electrolytic Production of Bromine

The Dow Chemical Company | Midland, Michigan

In the late 1800s, Herbert Dow was one of many would-be entrepreneurs striving to transform America's vast, untapped natural resources into commercial products that could compete with those of Europe's chemical manufacturers. Dow dreamed of finding an efficient way to make chemical products from the plentiful deposits of brine just beneath the surface of his native Midwest. In the years that followed, the commercial success of these endeavors helped to promote the growth of the American chemical industry. Learn more.

Fluid Bed Reactor

ExxonMobil Corporation | Baton Rouge, Louisiana

The first commercial circulating fluid bed reactor, PCLA #1 (Powdered Catalyst Louisiana), went on stream on May 25, 1942, in the Baton Rouge Refinery of the Standard Oil Company of New Jersey (now ExxonMobil Corporation). This first use of powdered catalysts in continuous operation allowed the efficient cracking of heavy gas oils to meet the growing demand for high-octane fuels. Today, fluid bed reactors are in use worldwide for the manufacture of fuels, chemical intermediates, and plastics. Learn more.

High Performance Carbon Fibers

Dillard University | New Orleans, Louisiana

Norbert Rillieux (1806-1894) revolutionized sugar processing with the invention of the Multiple Effect Evaporator under Vacuum. Rillieux’s great scientific achievement was his recognition that at reduced pressure the repeated use of latent heat would result in the production of better quality sugar at lower cost. Rillieux’s invention is widely recognized as the best method for lowering the temperature of all industrial evaporation and for saving large quantities of fuel. Learn more.

Penicillin Production through Deep-tank Fermentation

Pfizer, Inc. | New York City, New York

In the early 20th century, Pfizer developed innovative fermentation technology, first applying it to the mass production of citric acid. In subsequent years, Pfizer perfected deep-tank fermentation, an aseptic process for growing large quantities of microorganisms which require oxygen for survival. When scientists in England were unable to produce penicillin on a large scale during World War II, Pfizer attempted manufacturing using this process. In a major feat of chemical engineering, the company rebuilt an old ice plant, which had the refrigeration machinery required for submerged fermentation, and opened the world’s first large-scale penicillin facility on March 1, 1944.
