The sublimation that occurs at the solid-gas boundary (critical sublimation point) (corresponding to boiling in vaporization) may be called rapid sublimation, and the substance sublimes rapidly. The words "gradual" and "rapid" have acquired special meanings in this context and no longer describe the rate of sublimation. [citation needed]
In thermodynamics, the enthalpy of sublimation, or heat of sublimation, is the heat required to sublimate (change from solid to gas) one mole of a substance at a given combination of temperature and pressure, usually standard temperature and pressure (STP). It is equal to the cohesive energy of the solid.
Sublimation or sublimate may refer to: Sublimation, by Canvas Solaris, 2004; Sublimation (phase transition), directly from the solid to the gas phase; Sublimation (psychology), a mature type of defense mechanism; Sublimate of mercury, or Mercury(II) chloride; Volcanic sublimate, a product of deposition from vapors around volcanic vents
Membrane separation processes operate without heating and therefore use less energy than conventional thermal separation processes such as distillation, sublimation or crystallization. The separation process is purely physical and both fractions (permeate and retentate) can be obtained as useful products.
