In this paper, the absorbent carryover effect in a designed counter-flow enthalpy exchanger is investigated. In a built prototype of the liquid desiccant dehumidifier, air and the absorbent solution are in contact and flow through a packed multi-channel polymer tower in a counter-flow pattern. To avoid the absorbent carryover, the tower is equipped with an eliminator. Experimental measurements ...
Packed towers are widely used for distillation processes due to their higher separation efficiency and capacity in comparison to tray towers. The separation efficiency of the tower strongly depends on the liquid flow behaviour inside the packing, which becomes more complex with the appearance of a second liquid phase. Such flow behaviour can be observed in the three-phase distillation process i...
This paper presents a mixed-integer nonlinear programming (MINLP) model for the optimal design of mechanical counter-flow cooling towers, subjected to standard design constraints. The objective function consists of the minimization of the total annual cost, which includes the capital cost of the cooling tower (that depends on the filling material and the air flowrate) and the operating cost (th...
