Supercritical water oxidation (SCWO) is a process that occurs in water at temperatures and pressures above a mixture's thermodynamic critical point. Under these conditions water becomes a fluid with unique properties that can be used to advantage in the destruction of recalcitrant and hazardous wastes such as polychlorinated biphenyls (PCB) or per- and polyfluoroalkyl substances (PFAS). Supercritical water has a density between that of water vapor and liquid at standard conditions, and exhibits high gas-like diffusion rates along with high liquid-like collision rates. In addition, the behavior of water as a solvent is altered - it behaves much less like a polar solvent. As a result, the solubility behavior is "reversed" so that oxygen, and organics such as chlorinated hydrocarbons become soluble in the water, allowing single-phase reaction of aqueous waste with a dissolved oxidizer. The reversed solubility also causes salts to precipitate out of solution, meaning they can be treated using conventional methods for solid-waste residuals. Efficient oxidation reactions occur at low temperature with reduced NOx production.
The Fischer–Tropsch process (FT) is a collection of chemical reactions that converts a mixture of carbon monoxide and hydrogen, known as syngas, into liquid hydrocarbons. These reactions occur in the presence of metal catalysts, typically at temperatures of 150–300 °C (302–572 °F) and pressures of one to several tens of atmospheres. The Fischer–Tropsch process is an important reaction in both coal liquefaction and gas to liquids technology for producing liquid hydrocarbons.

Food engineering is a scientific, academic, and professional field that interprets and applies principles of engineering, science, and mathematics to food manufacturing and operations, including the processing, production, handling, storage, conservation, control, packaging and distribution of food products. Given its reliance on food science and broader engineering disciplines such as electrical, mechanical, civil, chemical, industrial and agricultural engineering, food engineering is considered a multidisciplinary and narrow field.
Indira Gandhi Centre for Atomic Research (IGCAR) is one of India's premier nuclear research centres. It is the second largest establishment of the Department of Atomic Energy (DAE), next to Bhabha Atomic Research Centre (BARC), located at Kalpakkam, 80 km south of Chennai, India. It was established in 1971 as an exclusive centre dedicated to the pursuit of fast reactor science and technology, due to the vision of Vikram Sarabhai. Originally, it was called Reactor Research Centre (RRC). It was renamed to Indira Gandhi Centre for Atomic Research (IGCAR) by the then Prime Minister of India Rajiv Gandhi in December 1985. The centre is engaged in broad-based multidisciplinary programme of scientific research and advanced engineering directed towards the development of fast breeder reactor technology in India.
The California Fuel Cell Partnership (CaFCP) is a public-private partnership to promote hydrogen vehicles (including cars and buses) in California. It is notable as one of the first initiatives for that purpose undertaken in the United States. The challenge is which come first, hydrogen cars or filling stations.
The National Historic Chemical Landmarks program was launched by the American Chemical Society in 1992 to recognize significant achievements in the history of chemistry and related professions. The program celebrates the centrality of chemistry. The designation of such generative achievements in the history of chemistry demonstrates how chemists have benefited society by fulfilling the ACS vision: Improving people's lives through the transforming power of chemistry. The program occasionally designates International Historic Chemical Landmarks to commemorate "chemists and chemistry from around the world that have had a major impact in the United States".
Dynamotive Energy Systems Corporation is a Canadian based Renewable Energy Company which specializes in fast pyrolysis, a process which creates a product named bio-oil. Its only other residue is char.
Refined coal is the product of the coal-upgrading technology that removes moisture and certain pollutants from lower-rank coals such as sub-bituminous and lignite (brown) coals, raising their calorific values. Coal refining or upgrading technologies are typically pre-combustion treatments and processes that alter the characteristics of coal before it is burned. Pre-combustion coal-upgrading technologies aim to increase efficiency and reduce emissions when coal is burned. Depending on the situation, pre-combustion technology can be used in place of or as a supplement to post-combustion technologies to control emissions from coal-fueled boilers.
Nitrogen generators and stations are stationary or mobile air-to-nitrogen production complexes.
Government Engineering College, Kozhikode (GECK), is a public engineering institute established by the Department of Technical Education under the Government of Kerala in India. It was one of the five public engineering institutes sanctioned in 1999 by the Government of Kerala. It is one of the 138 institutes affiliated to the APJ Abdul Kalam Technological University since 2015.
Electrochemical engineering is the branch of chemical engineering dealing with the technological applications of electrochemical phenomena, such as electrosynthesis of chemicals, electrowinning and refining of metals, flow batteries and fuel cells, surface modification by electrodeposition, electrochemical separations and corrosion.
Food physical chemistry is considered to be a branch of Food chemistry concerned with the study of both physical and chemical interactions in foods in terms of physical and chemical principles applied to food systems, as well as the applications of physical/chemical techniques and instrumentation for the study of foods. This field encompasses the "physiochemical principles of the reactions and conversions that occur during the manufacture, handling, and storage of foods."
A separation process is a method that converts a mixture or a solution of chemical substances into two or more distinct product mixtures, a scientific process of separating two or more substances in order to obtain purity. At least one product mixture from the separation is enriched in one or more of the source mixture's constituents. In some cases, a separation may fully divide the mixture into pure constituents. Separations exploit differences in chemical properties or physical properties between the constituents of a mixture.
Ralph Landau was an American chemical engineer and entrepreneur active in the chemical and petrochemical industries. He is considered one of the top fifty foundational chemical engineers of the first half of the 20th century, and one of the 75 most distinguished contributors to chemical enterprise. He has published extensively on chemical engineering and holds a significant number of patents.
E-diesel is a synthetic diesel fuel for use in automobiles. Currently, e-diesel is created at two sites: by an Audi research facility Germany in partnership with a company named Sunfire, and in Texas. The fuel is created from carbon dioxide, water, and electricity with a process powered by renewable energy sources to create a liquid energy carrier called blue crude which is then refined to generate e-diesel. E-diesel is considered to be a carbon-neutral fuel as it does not extract new carbon and the energy sources to drive the process are from carbon-neutral sources.
Carbon Engineering Ltd. is a Canadian-based clean energy company focusing on the commercialization of direct air capture (DAC) technology that captures carbon dioxide directly from the atmosphere.
Exxon donor solvent process (EDS) is a coal liquefaction process developed by Exxon Research and Engineering Company, starting in 1966. The process converts solid coal directly to liquid synthetic fuels which could be used as a substitute for petroleum products. The process does not involve an intermediate step of coal gasification. Exxon operated a pilot plant in Texas from 1980 until 1982.
