Aim of the event:
For design and production of industrial goods pure substances and mixtures of specific compositions are required. Usually such substances are component materials and occur in nature only as arbitrary mixtures. Thus, processes must be employed first to separate the constituents from each other or to remove undesired components. The separation methods developed in the area of Thermal Process Engineering are based on the gradients of field quantities such as chemical potential and temperature. The kinetics of the processes depend on the conditions of heat and mass transfer and on the displacement of the system from equilibrium.
The purpose of the lectures is to impart the basic knowledge of elementary thermal processes and phase equilibria of multicomponent fluid systems. The analytical relationships are deduced from the thermodynamics of mixtures and graphical methods are adopted for rough estimations of process parameters.
