Classification of processes and apparatus

Classification of the basic processes and apparatus Classification of processes according to the method of propulsion forces: - mass transfer - hydromechanical - mechanical – heat transfer - chemical
1) Mass transfer is the transition of a substance from one phase to another is carried out due to diffusion. Depending on the transition from phase to phase the process is called: TV → W (melting) g → W (condensation, absorption) W → TV (crystallization) TV → g (sublimation) W → f (extraction) g → TV (adsorption) W → g (evaporation, desorption) W ↔ p (rectification) The driving force in mass transfer processes is the concentration difference of the speed of the process is determined by laws of mass transfer.
