Adipic acid dihydrazide (ADH) is a chemical used for cross-linking water-based emulsions. It can also be used as a hardener for certain epoxy resins. [2] ADH is a symmetrical molecule with a C4 backbone, and the reactive group is C=ONHNH 2. Dihydrazides are made by the reaction of an organic acid with hydrazine. Other dihydrazides with ...
A schematic of a direct solar dryer. Direct solar dryers expose the substance to be dehydrated to direct sunlight.Historically, food and clothing was dried in the sun by using lines, or laying the items on rocks or on top of tents. [2]
Schematic diagram of a cryogen-free, or dry, dilution refrigerator precooled by a two-stage pulse tube refrigerator, indicated by the dotted rectangle. A 3 He/ 4 He dilution refrigerator is a cryogenic device that provides continuous cooling to temperatures as low as 2 mK , with no moving parts in the low-temperature region.
An example process flow diagram for this system. Lean, water-free glycol (purity >99%) is fed to the top of an absorber (also known as a "glycol contactor") where it is contacted with the wet natural gas stream. The glycol removes water from the natural gas by physical absorption and is carried out the bottom of the column.
As shown on the right, the trays most commonly have slits to provide more surface area between the food and the air. A dehydrator's heating element, fans and vents simultaneously work to direct hot air over the food, accelerate surface evaporation, and warm the food to also release moisture from its interior. This process continues until the ...

[1]Founded in 1991 by President Peter Vinci, an electro-mechanical engineer, the company operates through a traditional three-step distribution process and serves the automotive, fleet, industrial, and agricultural industries.
Environmental technology (envirotech) is the use of engineering and technological approaches to understand and address issues that affect the environment with the aim of fostering environmental improvement. It involves the application of science and technology in the process of addressing environmental challenges through environmental ...
Schematic diagram of a typical rotating biological contactor (RBC). The treated effluent clarifier/settler is not included in the diagram. A rotating biological contactor or RBC is a biological fixed-film treatment process used in the secondary treatment of wastewater following primary treatment.
