The Haber process for the [[Ammonia production|production of ammonia]] by combining hydrogen and [[nitrogen]] was first patented by a chemist, [[Fritz Haber]], in 1908.

It was first used on an industrial scale by the Germans during World War I.

Chemical engineering is one of the broadest fields of engineering. This stems from the fact that the discipline of chemical engineering is founded on mathematics and incorporates all of the basic sciences such as chemistry, physics and biology.

The disciplinary definition would be that chemical engineering is the profession in which knowledge of mathematics, physics, chemistry and biology, gained by study, experience and practice, is applied with judgement to develop economic and safe ways of converting raw materials or chemicals into more useful products to benefit mankind.[1][2]

The occupational definition would be that chemical engineering is a field that deals with industrial and natural processes that involve the chemical, physical or biological transformation of matter or energy into forms useful for mankind, economically and safely without compromising the environment.[2]

Perhaps, the simplest definition is that chemical engineering is the design, development and management of a wide and varied spectrum of industrial and other endeavors.[3]

History

The industrial revolution of the early 1800's gave birth to many large-scale chemical plants including the Lead-Chamber method for producing sulfuric acid. The raw materials included a nitrate which, in the final stage of the process, was lost to the atmosphere as nitric oxide gas and had to be replaced by costly fresh nitrate imported from Chile. In 1827, the French chemist Joseph-Louis Gay-Lussac developed a tower that recovered most of the nitrogen oxide gases formed and reduced the consumption of nitrate. The first Gay-Lussac tower was installed at a plant in France in 1837. However, its use was not widespread until a British chemist, John Glover, invented an improved version of the tower, patented in England in 1859. By the 1870s, the Glover–Gay-Lussac system was used throughout Britain and Europe. Because Glover's tower was essentially a mass transfer tower, he is often considered to be the first chemical engineer.[4]

In 1791, a French physician, Nicholas Le Blanc, patented a method of producing sodium carbonate from sea salt.[5] By 1810, it was in widespread use. However, it produced the hazardous byproducts hydrochloric acid, nitrogen oxides, sulphur and chlorine gas. In 1811, Augustine Jean Fresnel, a French physicist, discovered a cleaner process for producing sodium carbonate by bubbling carbon dioxide through an ammonia-containing brine. Attempts to build large-scale plants using Fresnel's process were unsuccessful. In 1863, some fifty years later, a Belgian chemist, Ernest Solvay, successfully applied Fresnel's process using a tall gas absorption tower in which carbon dioxide bubbled up through a descending flow of brine, together with efficient recovery and recycling of the ammonia. Use of the Solvay process soon became widespread and it is still used today. Ernest Solvay's work is sometimes thought of as one of the first accomplishments of chemical engineering.[6]

The Haber process for the production of ammonia by combining hydrogen and nitrogen was first patented by a chemist, Fritz Haber, in 1908. In 1910, an engineer, Carl Bosch, while working for the German chemical company BASF, successfully commercialized the process and secured further patents. It was first used on an industrial scale by the Germans during World War I. Haber and Bosch were later awarded Nobel prizes, in 1918 and 1931 respectively, for their work in overcoming the chemical and engineering problems posed by the use of large-scale high-pressure technology. Their process is often referred to as the Haber-Bosch process and is considered to be one of the major chemical engineering achievements because it made possible the large-scale production of ammonia-based fertilizers that transformed the world's food production.[7][8]

Under the British Alkali Act of 1863, an Alkali Inspector and four subinspectors were appointed to curb the discharge into the air of hydrochloric gas from the Le Blanc sodium carbonate plants.

In 1888, the first chemical engineering curriculum, designed by Lewis Norton, began at the Massachusetts Institute of Technology (MIT). In 1892 and 1894, respectively, the University of Pennsylvania and Tulane University in Louisiana also began chemical engineering programs.[10]

In 1908, the American Institute of Chemical Engineers (AIChE) was formed and, in 1922, the Institution of Chemical Engineers (IChemE) was founded in England.

In 1923, Professor E.C. Williams established the first chemical engineering program in England at the University College London (UCL).[12]

Chemical engineering applications

The process design, operation and management of large-scale industrial facilities such as:

Designing processes and facilities for:

Environmental engineering tasks such as the design of air pollution and water pollution control and mitigation facilities, performing environmental impact studies and air pollution dispersion modeling studies, and selection or design of facilities to comply with governmental environmental protection regulations.

Safety engineering work such as performing hazardous operation studies (Hazops), risk analyses, and establishing and implementing safe operating procedures for industrial facilities.

Research and development in the fields of fuel cells, nanotechnology down to the cellular level, computer chips, and other leading edge technologies.

In all of the above fields of endeavor, chemical engineers may also function as consultants, lawyers reviewing new technology patents, sales engineers, instrumentation and control engineers, and equipment manufacturers.

Chemical and Biomolecular Engineering

In recent years, chemical engineering has become more and more involved in biomolecular engineering. At a 1992 meeting of the National Institutes of Health (NIH), they defined the term, "Biomolecular Engineering," as Research and development at the interface of chemical engineering and biology with an emphasis at the molecular level.[14]

Many universities now offer degree programs in Chemical and Biomolecular Engineering.[14][15][16][17] In the future, chemical engineering will not only encompass design work at large scales (e.g., petroleum refineries and petrochemical plants) but will also encompass work at very small scales down to the cellular level.[18]
