MATHEMATICAL SIMULATION OF THE PROCESS OF NICKEL OXIDE RECOVERY IN A TUBE-TYPE ROTARY KILN

摘要

Solid-phase reduction of nickel oxide is an important process stage in nickel production. The mathematical model of the steady-state operation of the apparatus is an important component, which allows determining the optimal operating mode of the rotary tube furnace (TRK). The automated software application ReactOp is capable of generating a mathematical model of the reactor on the basis of hydrodynamic and thermal models supplemented by the mechanism of chemical transformations, kinetic parameters, thermal and physical properties, and heat transfer parameters. The software complex is equipped with a user-friendly interface, which allows to interactively generate a runtime program based on the mathematical model.
