Mathematical Model of Membrane Distillation
Hvožďa, Jiří ; Komínek, Jan (oponent) ; Kůdelová, Tereza (vedoucí práce)
The master's thesis deals with membrane distillation, particularly from the mathematical point of view. Membrane distillation is a thermally driven separation process using a porous membrane to set liquid and gas phases apart. The liquid evaporates and its vapour crosses the membrane's pores. In this process both heat and mass transfers occur. They are governed by a system of partial differential equations. Another model is built based on the analogy to electrical circuits, the first law of thermodynamics, the mass balance, and empiric relations. It is verified with experimentally measured data from a new alternative distillation unit, in which polymeric hollow fibers are used for both membrane module and condenser. The performance and efficiency of the system are evaluated, and further improvements are proposed.
