pressure process
21pressure feed — noun mechanical system of lubricating internal combustion engines in which a pump forces oil into the engine bearings • Syn: ↑lubricating system, ↑force feed lubricating system, ↑force feed, ↑pressure feed lubricating system • Hypernyms:… …
22pressure stage — noun : the stage in the process of expansion and of energy transformation in which steam after expanding through a predetermined pressure range in a steam turbine gives up its acquired kinetic energy to the moving blades without further drop in… …
23Catalyst for pressure swing adsorption — Pressure Swing Adsorption (PSA) processes rely on the fact that under pressure gases tend to be attracted to solid surfaces, or adsorbed. The higher the pressure, the more gas is adsorbed; when the pressure is reduced, the gas is released, or… …
24Adiabatic process — This article covers adiabatic processes in thermodynamics. For adiabatic processes in quantum mechanics, see adiabatic process (quantum mechanics). For atmospheric adiabatic processes, see lapse rate. In thermodynamics, an adiabatic process or an …
25Isochoric process — An isochoric process, also called a constant volume process, an isovolumetric process, or an isometric process, is a thermodynamic process during which the volume of the closed system undergoing such a process remains constant. An isochoric… …
26Thermodynamic process — A thermodynamic process may be defined as the energetic evolution of a thermodynamic system proceeding from an initial state to a final state. Paths through the space of thermodynamic variables are often specified by holding certain thermodynamic …
27Bergius process — The Bergius Process is a method of production of liquid hydrocarbons for use as synthetic fuel by hydrogenation of high volatile bituminous coal at high temperature and pressure. It was first developed by Friedrich Bergius in 1913, in 1931… …
28Haber process — The Haber process, also called the Haber–Bosch process, is the nitrogen fixation reaction of nitrogen and hydrogen, over an iron substrate, to produce ammonia. Enriching the Earth: Fritz Haber, Carl Bosch, and the Transformation of World Food… …
29Isobaric process — An isobaric process is a thermodynamic process in which the pressure stays constant: Delta p = 0 The term derives from the Greek isos, equal, and barus, heavy. The heat transferred to the system does work but also changes the internal energy of… …
30Dry sterilisation process — The term dry sterilisation process, DSP, denotes a dry aseptic sterilisation process. It is used for instance in the beverage industry during cold aseptic filling of beverages (juices, waters, UHT milk, etc.) into plastic bottles made from PET or …
