Pascalization, bridgmanization, high pressure processing (HPP) [1] or high hydrostatic pressure (HHP) processing [2] is a method of preserving and sterilizing food, in which a product is processed under very high pressure, leading to the inactivation of certain microorganisms and enzymes in the food.

Urea plant using ammonium carbamate briquettes, Fixed Nitrogen Research Laboratory, ca. 1930 Carl Bosch, 1927. The Bosch–Meiser process is an industrial process, which was patented in 1922 [1] and named after its discoverers, the German chemists Carl Bosch and Wilhelm Meiser [2] for the large-scale manufacturing of urea, a valuable nitrogenous chemical.
High-pressure chemistry is concerned with those chemical processes that are carried out under high pressure – pressures in the thousands of bars (100 kPa) or higher.High-pressure processes are generally faster and have a higher conversion efficiency than processes at ambient pressure.
Carl Bosch (German pronunciation: [kaʁl ˈbɔʃ] ⓘ; 27 August 1874 – 26 April 1940) was a German chemist and engineer and Nobel Laureate in Chemistry. [2] He was a pioneer in the field of high-pressure industrial chemistry and founder of IG Farben, at one point the world's largest chemical company.
inject the N 2 and H 2 that did not react into the chemical reactor again; recycle the heat produced. To overcome the problems associated with high pressure, Haber called upon the talents of Robert Le Rossignol, who designed the equipment necessary for the success of the process. [50] Early in 1909, Haber discovered that osmium could serve as a ...
Linde Gas supplies industrial gases, medical gases, specialty gases, refrigerants and other chemicals. Depending on the gas and the quantity required, these may be supplied in portable high-pressure gas cylinders, in liquefied form by road tanker, from on-site gas generators or in gaseous form via pipeline to large customers.
According to the NOVA classification system, ultra-processed foods are industrial formulations made entirely or mostly from substances extracted from foods (oils, fats, sugar, starch, and proteins ...
The Leuna works (German: Leunawerke) in Leuna, Saxony-Anhalt, is one of the biggest chemical industrial complexes in Germany. [1] [2] The site, now owned jointly by companies such as TotalEnergies, BASF, Linde plc, and DOMO Group, covers 13 km 2 and produces a very wide range of chemicals and plastics.
