CONTROL OF PROPANE PYROLYSIS PROCESS IN NONSTATIONARY CONDITIONS

Calculation of propane pyrolysis proceeding in nonstationary conditions caused by coke deposition on the walls of the coil and leading to decrease of propylene productivity of the process has been given. For maintaining the productivity at a constant level the control function that takes into account the dependence of the propylene yield on time, reactor loading and pressure drop along the reactor due to coke formation has been proposed. Entering it into the mathematical model of the stationary process will allow stabilizing the process at any time during the operation of the furnace
