PROKOPOVÁ, Z.

Abstract

The main aim of the presented paper is to develop a mathematical model design methodology for a special tanning facility – paddle tumbler. The mentioned equipment can be described as a type of rotary reactor. A mathematical analysis and simulation calculations of the plant brings optimization of reaction time and cost saving. The non-isothermal and non-adiabatic rotary reactor – paddle tumbler for an enzymatic hydrolysis of chromium tannery wastes is considered. The assumption has two basic reasons. Firstly, the paddle tumblers are usually used directly in the tannery wastes point of origin. Secondly, it needs only small investment to plant changes for its available utilization. Both reasons support economical aspects of the desired process. The developed mathematical model enables to set up different changes of various parameters without any complex industrial experiments. A deep analysis and comparisons of experimental and simulation (computed) data were performed for verification of models. Some parameters and constants of mathematical relations had to be derived previously from measured industrial variables. The paper brings the conditions, methodology and restrictions for the reaction temperature. All computations were performed in the MATLAB+SIMULINK environment.
