HEAT AND MASS TRANSFER AND KINETIC PROCESSES MODELING IN A METHANE STEAM CONVERSION FACILITY

This paper deals with one of the most interesting methods of lowering heat losses: thermochemical recuperation (TCR) of waste heat present in high-temperature flue gases via methane steam reforming. An earlier proposed process flow diagram for TCR in a glass production facility was revised and a mathematical model was developed to predict the heat and mass transfer phenomena that take place in the catalytic chemical reactor included in that process. Comparison of data obtained by the new proposed model and published data confirmed the feasibility of using it in the investigation and synthesis of TCR processes. Obtained results also permit to find optimal temperature profile in order to increase the hydrogen rate formation.
