THE CALCULATION OF THE COEFFICIENTS OF THE LANGMUIR EQUATION FOR THE FORMATION OF A DATA BANK ON THE ISOTHERMS OF ADSORPTION

Abstract

Problems of design of the adsorptive installations with adsorbers of periodic action with a stationary layer of adsorbent are considered. The method of calculation of coefficients of isotherms of adsorption of Lengmyur by minimization of not knittings of skilled and settlement data on condition of uncertainty of borders of area of optimization is stated. A basis of calculation is set of a method of the smallest squares and a method of scanning of a fragment of area of a research of a two-parametrical task with consecutive search of about extreme area and its research with the decreasing steps. The calculated coefficients of the equation of Lengmyur as the databank element on isotherms of adsorption which is a fragment of the computer-aided engineering system of the adsorptive installations are provided. On examples good convergence of results of calculations of isotherms of adsorption with experimental data is shown. The block scheme of the computer-aided engineering system of adsorbers with a stationary layer of adsorbent allowing to carry out calculation of the device for various characteristic areas of isotherms of adsorption, and also to fill up a databank with information on new systems an adsorbate adsorbent is provided. The algorithm for calculating coefficients of the equation of Langmuir adsorption isotherms in uncertainty optimization allows to develop a computer-aided design of adsorption units. Shows the block diagram of the systems of the automated designing adsorbers periodic action with a stationary layer of adsorbent.
