Simulation of adsorption processes in gas cleanup filters

New emerging technologies developed for efficient, clean, coal processing require research into the phenomena used in these processes. In this paper we will deal with the problem of cleaning gas obtained by means of coal gasification. Realisation of this process takes the form of filters with various properties. The efficiency of the gas cleaning process can be influenced by several factors. One class of factors is the physical properties of the granules used in the filter. These properties influence the way the granules move in the filter bed. Another class of problems concerns the adsorption properties of the granules. The quality of adsorption influences the efficiency of a filter and thus the costs of the gas cleaning process. The optimal combination of adsorption and physical properties of granules leads to the optimal exploitation of the filter, both from the point of view of costs and the degree of gas cleaning. While the physical properties of granules have been investigated, the adsorption properties still remain an unknown factor (or at least a factor with an unknown impact on the filter efficiency) from the point of view of filter design and exploitation. The main goal of our research was to investigate and simulate the adsorption capability of granules. The expected result was the determination of optimal counterplay between physical and adsorption processes. A simulation model with visualisation module has been developed and inxplemented.
