Steady State Model

Heat and mass transfer analysis between a desiccant-air contact system in a packed tower has been studied in application to air dehumidification employing liquid desiccant, namely calcium chloride. Ceramic 2 in. Raschig rings are used as the packing material. To predict the tower performance, a steady-state model which considers the heat and mass transfer resistances of the gas phase and the mass transfer resistance of the liquid phase is developed. The governing equations are solved on a digital computer to simulate the performance of the tower. The various parameters such as the effect of liquid concentration and temperature, air temperature and humidity and the rates of flow of air and liquid affecting the tower performance have been discussed.

Methane Elimination

The objective behind this study is to select a suitable inorganic packing material for methane biofiltration. Three packing materials are to be compared: two rock materials (average particles' sizes: 2 and 5 mm) and one porous clay particles (average particle size of 7 mm). The main parameter used to assess the efficiency of the packing material is the methane elimination capacity. The study reveals that the rock material having an average particle size around 2 mm is to be preferred. This result is probably due to its high specific surface area and to its good surface properties as compared to the other 2 tested porous materials. The influence of the nonirrigation with the nutrient solution of the biofilter is also investigated. It has been found that nonirrigation of biofilter causes the biofilter performance to decrease significantly (e.g., 45% decrease in 1 week) even with the humidification of the gas phase prior to its introduction into the biofilter.

Packing Column

A new approach to the mathematical modeling of packed absorption columns operating in the emulsification mode, which makes it possible to estimate the actual surface of the contact phase of the mass transfer products is presented. Equations for calculating the average diameter of the gas phase bubbles, the thickness of the liquid film between the bubbles in the packed absorption mass-exchange column operating in the emulsification mode are derived on the basis of the equality of the formation energy of the phase interface and the base of their overcoming the hydraulic resistance. A comparison of technological and geometric parameters of a typical packed absorption column with Raschig rings and a column with S-Aisi316Tiε-0.82 packing material based on the metalworked wastes.
