Fluidized bed reactor - Wikipedia

Fluidized bed reactors are a relatively new tool in the chemical engineering field. The first fluidized bed gas generator was developed by Fritz Winkler in Germany in the 1920s. One of the first United States fluidized bed reactors used in the petroleum industry was the alytic Cracking Unit, created in Baton Rouge, LA in 1942 by the Standard

Evaporative Vs. Cooling Crystallization Systems | Thermal Kinetics

Crystallization is a process by which a liquid transitions to the solid phase. The molecules of the liquid, when subjected to appropriate physical conditions (temperature, pressure, residence time, agitation, etc.), arrange themselves in highly organized, tightly bonded structures. These are called crystals, and the pattern of arrangement, or the crystal lattice, depends on the …
