Visualization and Analysis of Adsorption Kinetics by Using Image Processing Algorithm

Abstract

This paper provides an analysis of the adsorption kinetics by using image processing algorithm. Rapid adsorption kinetics is increasingly important because it offers a good mass transfer hence improves the efficiency of the sorption system. For adsorption kinetics, it is required to determine the first stage of the measurement precisely. Therefore, selecting the proper method becomes essential. Simple experimental setup was developed for evaluating adsorption equilibrium and adsorption kinetics of Silica gel/water pair. The test apparatus comprises of adsorption cell, evaporator/condenser, piping line, and measurement devices for temperature and pressure. Silica gel types A was employed in the present study as the adsorbent material. A new method is proposed to calculate the adsorption kinetics by using the digital image analyzing. Algorithm for image analysis could semantically segment the adsorption process by creating images which represented the dataset for water level changes inside the evaporator.
